Mauritius Rainy Season: Summer Rain, Weather & What to Expect

You have booked, or nearly booked, and the forecast is showing a rain icon on every single day. This guide explains what that actually means. It covers when the wetter months fall, which parts of the island get meaningfully less rain than others, what a tropical shower is really like, and how to plan a summer trip without either pretending rain does not happen or cancelling over a weather app. All climate figures come from the Mauritius Meteorological Services.

Mauritius rainy season: quick answer

Mauritius has a warm, humid summer from November to April, when most of the year's rain falls. February and March are historically the wettest months and October the driest. The Meteorological Services is explicit that there is no sharply marked rainy season. Rain is usually showery rather than continuous, and one coast can be wet while another stays dry.

When is the rainy season in Mauritius?

Travellers call it the rainy season. Officially it is the summer.

●       The Mauritius Meteorological Services defines two seasons: a warm humid summer from November to April and a relatively cool dry winter from June to September

●       May and October are transition months, belonging fully to neither

●       Roughly two-thirds of the island's rain falls in summer — mean summer rainfall of 1,344 mm against a long-term annual total of 2,010 mm island-wide

●       Mean winter rainfall is 666 mm, so winter is drier but not dry

●       February and March are the wettest months; October is the driest

●       The seasonal temperature gap is small: mean summer 24.7°C against mean winter 20.4°C, a difference of 4.3°C

"Rainy season" is useful shorthand for November to April. It is not a description of daily conditions.

Figures are Mauritius Meteorological Services long-term means for the 1971–2000 reference period. They describe the normal shape of a year, not a forecast for any specific trip.

Does Mauritius really have a rainy season?

Not in the way the phrase suggests. The Mauritius Meteorological Services states plainly that although there is no marked rainy season, most of the rainfall occurs in the summer months. There is no monsoon, no defined onset and no fixed end — just a warmer half of the year that carries about two-thirds of the annual rainfall.

A monsoon climate has a switch: rain arrives on roughly the same date and dominates the day. Mauritius does not work like that. You get a seasonal tilt in probability — more showers, more humidity, more convective activity in summer — laid over an island small enough that conditions differ sharply from one coast to another on the same afternoon.

It explains why two travellers return from the same February week with opposite reports. One stayed west and swam every day; the other was east, or up on the plateau, and saw cloud. Both are describing Mauritius accurately.

Does it rain every day in Mauritius during summer?

No — but there are more days with some rain than in winter, and the count varies sharply by region.

Using Mauritius Meteorological Services long-term means, at the northern reference station of Pamplemousses:

●       January: rain on about 16 days of the month

●       February: about 16 days

●       March: about 15 days

●       April: about 15 days

●       December: about 10 days

●       November: about 8 days

Two things follow. Even in the wettest months, roughly half the days record no measurable rain. And a "rain day" counts anything over 1 mm — including a ten-minute shower at four o'clock on an otherwise bright day.

The same months look different elsewhere. In November the western station at Medine records rain on about 3 days; the eastern station at Fuel records about 10. That is not a rounding difference, and it is the most useful fact here for anyone choosing where to stay.

Does it rain all day?

Usually not, but sometimes yes. Most summer rain in Mauritius is showery — convective, localised and often brief, with bright spells between. But some weather systems do produce prolonged rainfall lasting many hours or more than a day, particularly when a tropical disturbance or an active weather system is nearby. Both patterns are normal parts of a Mauritian summer.

●       Most of it is convective. Heat and humidity build through the morning, cloud develops, showers break out in the afternoon. They can be heavy while they last

●       It is frequently localised. A downpour over the plateau while the west coast stays sunny is completely ordinary

●       Conditions change quickly. Bright morning, heavy hour, clear by evening is a common summer day

●       But prolonged rain does happen when a tropical disturbance or active trough sits near the island

●       Torrential rain episodes are a different category with their own official warning, covered below

We will not tell you showers only last twenty minutes. Some do; some last much longer. What the climatology supports is that summer rain here is concentrated rather than constant, and that whole washout days are the exception.

Why does my Mauritius forecast show rain every day?

Because a forecast icon is answering a different question from the one you are asking.

●       A rain symbol usually signals the possibility of showers somewhere in the forecast area, not a prediction of all-day rain. In a convective tropical summer, that possibility exists most days

●       Tropical convection is local. A model can be confident showers will develop without knowing whether yours is the bay that gets one

●       The forecast area is larger than your holiday. Rainfall varies enormously across a small island; an icon flattens all of it

●       Elevation is invisible in an icon. The plateau is consistently wetter and cloudier than the coast

●       A percentage is not a duration. A 60% chance of rain does not mean 60% of the day will be wet

Read the detailed official forecast instead. The Mauritius Meteorological Services publishes a written bulletin describing expected conditions by region, which tells you far more than a row of symbols.

What are the wettest months in Mauritius?

February and March are historically the wettest months in Mauritius, and October is the driest, according to Mauritius Meteorological Services long-term climatology. January is also wet. Rainfall then declines through April into the transition month of May. But monthly totals say nothing about how many holiday hours you will lose, because a high total can arrive in a few intense episodes.

The figures below use the northern reference station of Pamplemousses, so the year stays internally consistent. Treat them as the shape of the season, not the number for every beach — the same months are drier in the west and wetter in the east.

November rain

●       Rainfall: about 49.5 mm across roughly 8 days with measurable rain — one of the driest months of the year

●       Temperature: average day maximum around 30.0°C, night minimum around 19.1°C

●       Humidity: about 78%, among the lowest readings of the year

●       Sunshine: about 8.7 hours daily, the highest monthly figure at this station

●       Relative wetness: low — the start of summer, before rainfall builds

●       Cyclone season: the official season opens 15 November

●       Beaches: among the most reliable months of the year

●       Best for: summer warmth with minimal rain, at better value than December

●       Main consideration: November varies year to year and is not guaranteed dry

See our Mauritius in November guide for the full month.

December rain

●       Rainfall: about 127.5 mm across roughly 10 days — more than double November

●       Temperature: average day maximum around 30.7°C, night minimum around 20.9°C

●       Humidity: about 80% and rising

●       Sunshine: about 8.0 hours daily

●       Relative wetness: moderate — a clear step up from November, well below February

●       Cyclone season: within the official season

●       Beaches: good, with the warmest sea yet and the longest days of the year

●       Best for: festive travellers, families on school holidays, warm-water swimmers

●       Main consideration: peak demand and pricing, which limits how much flexibility you can buy

See our Mauritius in December guide.

January rain

●       Rainfall: about 206.2 mm across roughly 16 days

●       Temperature: average day maximum around 31.1°C, the hottest of the year, with nights around 22.1°C

●       Humidity: about 82%

●       Sunshine: about 8.1 hours daily — notably, still high despite the rainfall

●       Relative wetness: high, part of the wettest stretch of the year

●       Cyclone season: within the season and the historically most active January-to-March window

●       Beaches: the sea is at its warmest, and the sunshine figure shows days are far from washed out

●       Best for: warm-water swimmers, divers, and anyone happy to plan around afternoon showers

●       Main consideration: heat and humidity together make midday exertion harder than the temperature suggests

February rain

●       Rainfall: about 239.9 mm across roughly 16 days — the wettest month at this station

●       Temperature: average day maximum around 30.8°C, night minimum around 22.2°C

●       Humidity: about 84%, the highest of the year

●       Sunshine: about 7.7 hours daily

●       Relative wetness: the highest of the year, alongside March island-wide

●       Cyclone season: within the season and the most active historical window

●       Beaches: still usable on many days, but this is the most weather-dependent month

●       Best for: travellers prioritising warm sea and low visitor numbers over dry weather

●       Main consideration: the month to build genuine flexibility into the itinerary

Be clear about February: it is the wettest month, and that is a real consideration rather than a myth to argue away. But 240 mm does not fall evenly across the month. A large share can arrive in a handful of intense episodes, leaving many days bright. February is also among the quietest months for visitor numbers.

March rain

●       Rainfall: about 158.9 mm across roughly 15 days

●       Temperature: average day maximum around 30.6°C, night minimum around 21.7°C

●       Humidity: about 83%

●       Sunshine: about 7.6 hours daily

●       Relative wetness: high — island-wide, March ranks alongside February as wettest

●       Cyclone season: within the season and the tail of the most active window

●       Beaches: warm sea and good conditions between showers

●       Best for: late-summer warmth with far fewer crowds than the festive period

●       Main consideration: still humid and still well inside cyclone season

Our cyclone season guide explains what that actually means in practice.

April rain

●       Rainfall: about 157.6 mm across roughly 15 days

●       Temperature: average day maximum around 29.8°C, night minimum around 20.8°C

●       Humidity: about 84%

●       Sunshine: about 7.4 hours daily

●       Relative wetness: moderate to high, declining from the February-March peak

●       Cyclone season: within the season, which runs to 15 May for Mauritius

●       Beaches: good — sea still warm, conditions beginning to settle

●       Best for: shoulder-season travellers and honeymooners wanting warmth without festive pricing

●       Main consideration: neither reliably wet nor reliably dry. A genuine transition, and it varies

Which part of Mauritius gets the least rain?

The west coast is generally the driest part of Mauritius, and the central plateau is the wettest. The difference is driven by the south-easterly trade winds, which push moist air up against the island's mountains. The eastern and south-eastern slopes take the resulting rainfall, while the west sits in the rain shadow.

The mechanism explains almost every regional weather difference on the island.

●       Prevailing south-easterly trade winds blow across Mauritius for much of the year

●       They carry moist air forced upward by the island's mountains and central plateau

●       Rising air cools, condenses and drops its rain on the windward east and south-east, and over the high ground

●       The air descends on the leeward side, warming and drying — a rain shadow over the west

●       Elevation compounds it: the plateau is higher, cooler, cloudier and much wetter than any coast

The contrast in official long-term means, western station (Medine) against eastern (Fuel):

●       November: about 25.7 mm across 3 days in the west, against about 82.0 mm across 10 days in the east — more than three times the rain, on more than three times as many days

●       December: about 115.6 mm across 7 days in the west, against about 201.8 mm across 13 days in the east

Those are the same months on the same island, roughly forty-five minutes apart by car.

West coast — Flic en Flac, Tamarin, Black River, Le Morne

●       Generally the driest coastal region, sitting in the island's rain shadow

●       Sheltered from the trade winds, which also means calmer lagoons

●       The island's best sunsets, since you face the open horizon

●       Home to most dolphin, dive and catamaran operators, so weather-dependent excursions are close

●       Le Morne is drier than the east but windier than Flic en Flac, which is why kitesurfers gather there

●       It still rains. Drier is a climatological average, not a guarantee

More on Flic en Flac and Le Morne.

North coast — Grand Baie, Pereybère, Mont Choisy, Trou aux Biches, Cap Malheureux

●       Drier than the east and the plateau, though generally not as dry as the west

●       Sheltered lagoons, facing away from the prevailing south-easterlies

●       Among the highest sunshine figures on the island — about 8.7 hours daily in November, 8.1 in January

●       The widest choice of restaurants, bars and excursions if a wet afternoon means you want somewhere to go

●       A practical summer choice: dry-ish weather plus plenty to do when a shower passes

More on Grand Baie.

East coast — Belle Mare, Trou d'Eau Douce, Poste Lafayette, Palmar

●       The windward coast, taking the trade winds directly, and consistently wetter than the west

●       Also the windiest coast for much of the year, which affects lagoon conditions as much as rainfall

●       None of which makes it a poor choice: the east has the finest white sand in Mauritius, the largest resorts, wide shallow lagoons and access to Île aux Cerfs

●       It suits travellers whose plan is a full-service resort rather than daily excursions — if you are not leaving the property often, rainfall matters less than sand

More on Belle Mare.

South and south-east — Blue Bay, Pointe d'Esny, Mahébourg, La Cambuse

●       Exposed to the same trade-wind flow as the east, and wetter than the west

●       Local variation is pronounced: Blue Bay's sheltered marine park can be calm and clear while the coast toward Gris Gris is cliff and surf

●       The quietest and most local part of the island, with Mahébourg's working waterfront and Monday market

●       Good for road trips and Creole village life rather than guaranteed beach weather

Central plateau — Curepipe, Vacoas and the high ground

●       The wettest and cloudiest part of Mauritius by a wide margin, and several degrees cooler than any coast

●       Summer sunshine averages around 6.0 hours a day here, against 7.5 to over 8.0 on the coast

●       Cloud can sit on the plateau all morning while the coast is clear

●       This is why an inland excursion can feel like a different country from your hotel — if Chamarel looks grey on the forecast, your beach may still be fine

●       Plan plateau trips for the morning and keep them flexible

Is the west coast better during rainy season?

Climatologically, yes — the west is the driest coastal region of Mauritius, and in some months it records less than half the rainfall of the east. But drier on average is not the same as sunny, and rainfall should not be the only factor in choosing where to stay.

●       Rainfall and shelter favour the west, especially on a short, weather-dependent trip

●       Beaches: the east has finer sand — a real trade-off against rainfall if beach quality leads

●       Wind: the west is calmer, the east breezier, though summer trades ease and narrow the gap

●       Dining: the north has the widest choice, which matters on a wet evening

●       Activities: dolphin trips, diving and west-coast catamarans are all west; Île aux Cerfs is east

●       Hotel style: the largest full-service resorts cluster east; the west has more mid-market and boutique

●       Short trip: go west. Resort-centred trip: go anywhere

Mauritius rainy season vs cyclone season

They overlap heavily. They are not the same thing.

●       The rainy season is a climate pattern — when most of the year's rain normally falls, the November-to-April summer

●       Cyclone season is an official watch period, running 15 November to 30 April, extended to 15 May for Mauritius and the Seychelles

●       Ordinary summer rain has nothing to do with cyclones. A heavy February afternoon is tropical convection doing what it does

●       Tropical disturbances can produce prolonged heavy rainfall even with no cyclone warning in force, and even at some distance

●       A cyclone warning is a completely different signal from a shower forecast. Mauritius uses four classes, all built around expected gusts of 120 km/h

●       Being in cyclone season does not mean a cyclone will affect your trip. Most visits during the season see no warning at all

Our Mauritius cyclone season guide covers the warning classes and what to do if one is issued.

What is a torrential rain warning?

This is the official term, and it has a precise threshold.

●       Who issues it: the Mauritius Meteorological Services

●       The criterion: a torrential rain warning is issued following observations that accumulated rainfall has reached 100 millimetres in a given region, or is likely to reach 100 mm in a given region in the ensuing hour, and the rain is expected to continue

●       There is also a heavy rain warning, issued as far as practicable not less than 30 minutes and not more than 6 hours before heavy rain occurs, and a heavy rain watch ahead of that

●       How it reaches you: warnings are issued at regular intervals and broadcast on MBC and private radio stations, and published on the MMS website

●       What MMS warns about: flash floods and urban floods, water accumulation in flood-prone areas, overflow of rivulets, streams and rivers, and landslides on hill and mountain slopes

One detail that is easy to miss: MMS states that it provides flood warnings of a general nature, without being site-specific or quantifying water levels in rivers. A warning tells you a region is at risk, not whether a particular road or river crossing is passable. That judgement falls to you, and the safe answer is always to stay out of moving water.

If a warning is issued during your stay, follow official instructions and your accommodation's guidance. Never drive through a flooded road, however shallow it looks.

Can heavy rain cause flooding?

Yes. Intense tropical rainfall can produce localised flooding in Mauritius, and this is a genuine risk rather than a theoretical one.

●       Flash floods and urban floods can occur in any locality during a torrential rain episode

●       Rivers and streams can overflow, and MMS notes this often happens downstream, where it may not be raining heavily at all

●       Landslides can occur on hill and mountain slopes, treated as high-risk areas

●       Low-lying roads are the most commonly affected infrastructure

●       Risk depends on terrain, drainage and the specific event rather than being uniform across the island

This does not mean Mauritius floods every summer, or that the whole island is affected when it does. These are localised events tied to specific episodes. Take official warnings seriously when they come, and do not worry about them when they have not.

Are beaches still good during rainy season?

Yes, on most summer days. The sea is at its warmest between roughly December and March, days are long, and showers are typically localised and intermittent rather than continuous. But conditions vary by coast and by day, and thunderstorms, heavy rain, strong wind or marine warnings can make beach time unsuitable.

●       Many summer days contain genuinely good beach periods, often in the morning before convection builds

●       The sea is warm enough that a shower while you are already swimming is more comedy than problem

●       Sheltered west and north lagoons stay usable more often than the exposed east and south

●       Shade matters more on a showery day — the filao-backed beaches of the north give you somewhere to sit it out

●       Official marine and weather warnings always override general advice

Can you swim during rainy season?

Usually yes. Normal rain by itself does not make the lagoon unsafe, and Mauritius's reef creates sheltered, shallow water at most beaches. What does matter is thunderstorms, marine warnings, heavy swell, strong wind and cyclone conditions — those are different hazards from rain, and they take priority over any general guidance.

●       Rain alone: generally not a swimming hazard in a sheltered lagoon. You are already wet

●       Thunderstorms: get out. Lightning is the risk, not the rain

●       Heavy swell: MMS issues a warning when swell waves of 4.0 metres or above are expected, typically around 12 hours ahead

●       Marine and cyclone warnings: stay out of the water and follow official instructions

●       After heavy rain: runoff can reduce clarity near river mouths and stream outlets

If in doubt, ask at your hotel — coastal properties track conditions daily and will tell you straight.

Do catamaran and boat trips run when it rains?

Often yes. Rain is rarely the deciding factor on its own.

●       Light rain does not automatically cancel an excursion. Operators run in showers regularly

●       Cancellations are driven by wind, swell, sea state, visibility, thunderstorms and marine warnings — conditions on the water, not moisture in the air

●       Sea conditions deteriorate before land conditions do, which is why a trip can be cancelled on a day that looks fine from your balcony

●       The decision belongs to the operator. If they cancel, that is a safety judgement, not something to negotiate

●       Affected trips include catamaran cruises to Île aux Cerfs and Île aux Bénitiers, northern island excursions, speedboat charters and dolphin trips off Tamarin

●       Build flexibility in. Book weather-dependent excursions early in your stay, not on your final day

We cannot tell you any operator's refund or rescheduling policy — that varies by company and should be confirmed when you book.

What about snorkelling and diving?

Rain is one factor among several, and usually not the most important.

●       Runoff after heavy rainfall can reduce visibility near river mouths and stream outlets; offshore and reef sites are often less affected

●       Wind and sea state matter more than rain for whether a boat goes out at all

●       Sheltered sites hold up better — Blue Bay Marine Park, a shallow protected lagoon, is more resilient than exposed sites

●       The sea is warm in summer, a genuine argument for diving in the wetter months

●       Safety decisions belong to qualified operators. If a dive centre calls a site off, take the call

What to do in Mauritius when it rains

A wet afternoon is not a lost day on an island this compact. Most of these work in showers; a few need checking in heavy rain.

●       Port Louis Central Market — the best indoor hour in the country, genuinely interesting rather than a fallback

●       Blue Penny Museum and the Port Louis waterfront, plus Aapravasi Ghat, the UNESCO site telling the indentured-labour story that shaped modern Mauritius

●       Rum distillery tours and tea estate visits on the plateau, where cloud arguably suits the setting

●       L'Aventure du Sucre, the sugar museum at Beau Plan — large, indoors and better than it sounds

●       A long Creole lunch. Rain is the best possible excuse for a three-hour table

●       Spa treatments — demand spikes on wet afternoons, so book early in the day

●       Shopping at Bagatelle, Cascavelle or the Grand Baie strip

●       Scenic driving where safe — the Plaine Champagne road repays cloud, though not a torrential rain warning

●       Pamplemousses Botanical Garden in light showers, when the giant water lilies are at their best and the crowds have gone

Avoid during heavy rainfall: hiking in Black River Gorges, river and waterfall swimming, canyoning, and exposed coastal walking.

For dry-weather options, see our best things to do in Mauritius guide.

Waterfalls and rivers after heavy rain

This deserves its own warning, because it is where visitors most often misjudge conditions.

●       Heavy rain increases river flow quickly, and the increase can arrive well after the rain has stopped where you are standing

●       Flash flooding can occur in gorges, river beds and narrow valleys

●       Clarity and current change fast. A pool that was calm and clear yesterday can be brown and moving today

●       Photographs are not conditions. The image that made you want to visit Tamarind Falls, Eau Bleue or Cascade Mamzelle was taken on a specific day

●       Go with a licensed operator for canyoning and river activities, and accept their judgement if they call it off

●       MMS flood warnings are general, not site-specific. Nobody will tell you about your particular pool

Rain, humidity and mosquitoes

Warm, wet conditions do increase mosquito activity, and summer is the season when it matters most.

●       Humidity runs high through the wetter months — around 82% in January, 84% in February and April

●       Standing water after rain creates breeding sites, so activity rises in the weeks following wet spells

●       Activity is higher inland, in vegetated areas and near standing water; lower on open, breezy coastal frontage

●       The mosquitoes that matter here bite in daylight, peaking early morning and late afternoon — so repellent belongs in your day bag, not just on the dinner table

●       Use repellent with DEET, picaridin or IR3535

●       Air conditioning, intact window screens and maintained resort grounds all reduce exposure

●       There is no malaria in Mauritius and no antimalarial tablets are required

Our mosquitoes in Mauritius guide covers this properly.

What high humidity actually feels like

The temperature figures understate summer in Mauritius, because humidity does the heavy lifting.

●       Summer humidity runs roughly 78% to 84% at coastal stations, peaking in February

●       At 31°C and 82% humidity, sweat evaporates slowly — you feel hotter than the thermometer reads and tire faster

●       Wear light, loose, quick-drying natural fabrics. Linen and cotton beat synthetics comfortably

●       Drink more water than feels necessary

●       Plan strenuous activity for early morning — hikes, Le Morne, Black River Gorges, all before nine

●       Use air conditioning for recovery. An hour indoors mid-afternoon resets the day

●       Reapply sunscreen more often. Sweat and swimming shorten its life, and cloud does not block UV at 20° south

What to pack for Mauritius summer rain

You do not need serious wet-weather gear. You need things that dry.

●       Lightweight, quick-drying clothing — the single most useful category

●       A compact packable rain jacket rather than a heavy waterproof

●       A small umbrella for town and market visits, less useful on windy coasts

●       A waterproof phone pouch and a dry bag for boat trips and river activity

●       Footwear that dries, plus reef shoes for the lagoons

●       High-factor sunscreen and a hat — UV stays high through cloud

●       Insect repellent with DEET, picaridin or IR3535

●       A spare set of clothes in the car for day trips — excessive until the first afternoon it is not

●       One long-sleeved layer for air-conditioned restaurants and the cooler plateau

Is rainy season cheaper?

Partly, and not in the way most people assume. Mauritian pricing tracks source-market holidays far more closely than it tracks rainfall.

●       December and early January are the most expensive weeks of the year, despite falling in the wetter half. Christmas and New Year demand from European, South African and regional markets drives that, not the weather

●       July and August are also peak, tracking European summer holidays — and those are dry-season months

●       Late January through March is typically the quietest stretch, and where genuine value sits. It is also the wettest part of the year, which is precisely why demand falls

●       Easter creates a spike whose dates move each year

●       Hotel strategy varies by property — large resorts, boutiques and guesthouses do not price alike

So the wettest months are often cheaper, but because of when school holidays fall rather than any rule about rain. We do not publish percentage figures, because rates vary too widely by property, room category and channel to state responsibly.

Is Mauritius worth visiting during rainy season?

Yes, for most travellers, provided you choose your coast with some care and keep the itinerary flexible. Summer brings the warmest sea of the year, the longest days and a green, active landscape, at the cost of higher humidity, more rainfall and overlap with cyclone season. February and March carry the highest rainfall and the lowest visitor numbers simultaneously.

What summer genuinely offers:

●       The warmest sea of the year, roughly 27–28°C, and the longest daylight hours

●       A lush green interior and waterfalls at their most active

●       Christmas and New Year, which Mauritius does distinctively as a summer beach holiday

●       Quieter resorts and better availability from late January through March

●       High sunshine hours despite the rain — about 8.1 hours daily in January

What to weigh against it:

●       Humidity of 80% or more, which affects comfort more than the temperature does

●       Higher rainfall, concentrated in February and March, and overlap with cyclone season

●       Weather-dependent activities, especially boat trips, need flexible scheduling

●       Heavy-rain episodes can disrupt plans, and plateau excursions are more likely to be cloudy

Choose summer if you are a warm-water swimmer or diver, a family tied to school holidays, a honeymooner wanting long evenings and warm sea, or comfortable rearranging a day around the weather.

Consider winter instead if you are highly sensitive to humidity, planning a trip built around hiking, or someone for whom dry weather is genuinely the deciding factor. June to September is cooler, much drier and outside the cyclone season, at the cost of cooler water and stronger trade winds.

Frequently asked questions

When is rainy season in Mauritius?

Mauritius has a warm, humid summer from November to April, which travellers usually call the rainy season. Roughly two-thirds of the island's annual rainfall falls in these months. February and March are historically the wettest. The Meteorological Services notes there is no sharply marked rainy season, only a seasonal tilt toward summer rainfall.

What are the wettest months in Mauritius?

February and March are historically the wettest months island-wide, according to Mauritius Meteorological Services climatology, with January close behind. At the northern reference station, February records about 240 mm across roughly 16 days with measurable rain. October is the driest month of the year.

Does it rain every day in Mauritius?

No. Even in the wettest months, roughly half the days record no measurable rain at the northern reference station — about 16 rain days in January and February. Regional variation is large: in November the western station records rain on about 3 days while the eastern station records about 10.

Does it rain all day in Mauritius?

Usually not. Most summer rain is convective and showery, often falling in the afternoon with bright spells either side. However, some weather systems do produce prolonged rainfall lasting many hours or longer, particularly when a tropical disturbance is nearby. Both patterns occur in a normal Mauritian summer.

How long does rain last in Mauritius?

It varies too much to give a reliable figure. Typical summer showers are short and intense, but prolonged rainfall does occur with active weather systems. We will not claim showers only last twenty minutes, because some last considerably longer. The pattern is concentrated rather than constant.

Is Mauritius rainy in December?

Moderately. December records about 127.5 mm across roughly 10 rain days at the northern reference station — more than double November, but well below February. Sunshine averages about 8.0 hours daily and the sea is warm. December is also the most expensive month, driven by festive demand rather than weather.

Is Mauritius rainy in January?

Yes, relatively. January records about 206.2 mm across roughly 16 rain days at the northern station and is the hottest month at around 31.1°C. Notably, sunshine still averages about 8.1 hours daily, so days are far from washed out. The sea is at its warmest.

Is February too rainy for Mauritius?

Not for most travellers, but it is the wettest month. The northern station records about 240 mm across roughly 16 days, with humidity around 84%. A high monthly total can arrive in a few intense episodes rather than spread evenly. February is also one of the quietest months for visitor numbers.

Is March rainy in Mauritius?

Yes. March ranks alongside February as the wettest month island-wide, with about 159 mm across roughly 15 rain days at the northern station. It stays warm at around 30.6°C with humidity near 83%, and remains within the cyclone season. Conditions still include substantial sunshine between showers.

Does it rain a lot in April?

Moderately. April records about 158 mm across roughly 15 rain days at the northern station, declining from the February and March peak. It remains part of the official summer, and within the cyclone season, which runs to 15 May for Mauritius. April is a genuine transition month and varies considerably year to year.

Which coast of Mauritius is driest?

The west coast — Flic en Flac, Tamarin and Black River — is generally the driest, sitting in the rain shadow created by the island's mountains. In November the western station records about 25.7 mm against about 82.0 mm in the east. The central plateau is by far the wettest part of the island.

Is the west of Mauritius drier than the east?

Yes, substantially. The south-easterly trade winds push moist air against the mountains, so the east takes the rainfall while the west sits in the rain shadow. In December the western station records about 115.6 mm across 7 days against about 201.8 mm across 13 days in the east.

What is the best part of Mauritius during rainy season?

The west offers the driest climatology and calmest lagoons, making it the strongest choice if weather is your main concern. The north is nearly as dry and has far more restaurants and things to do when a shower passes. Choose the east for the finest sand if the resort itself is the holiday.

Can you still go to the beach during rainy season?

Yes, on most summer days. Showers are typically localised and intermittent, the sea is at its warmest, and mornings are often bright before convection builds. Sheltered west and north lagoons stay usable more often than exposed coasts. Official marine and weather warnings always take priority over general advice.

Can you swim when it rains in Mauritius?

Generally yes. Rain alone does not make a sheltered lagoon unsafe. What matters is thunderstorms, heavy swell, strong wind, marine warnings and cyclone conditions, which are different hazards. Get out of the water during thunderstorms. Heavy swell warnings are issued when waves of 4.0 metres or above are expected.

Are catamaran trips cancelled because of rain?

Not usually by rain alone. Operators regularly run in light rain. Cancellations are driven by wind, swell, sea state, visibility, thunderstorms and marine warnings — conditions on the water rather than moisture in the air. Book weather-dependent excursions early in your stay so there is room to reschedule.

Is rainy season the same as cyclone season?

No, though they overlap heavily. The rainy season describes a climate pattern — the November-to-April summer when most rain falls. Cyclone season is an official watch period running 15 November to 15 May for Mauritius. Ordinary summer rain has nothing to do with cyclones, and most trips during the season see no warning.

Can Mauritius flood during heavy rain?

Yes, locally. Intense rainfall can cause flash floods and urban floods, water accumulation in flood-prone areas, overflow of rivulets and rivers, and landslides on slopes. Risk depends on terrain, drainage and the specific event. The Meteorological Services issues torrential rain warnings when accumulated rainfall reaches or is likely to reach 100 mm in an hour.

What should I do if it rains on holiday?

Plenty. Port Louis Central Market, the Blue Penny Museum, Aapravasi Ghat, rum distilleries, tea estates, L'Aventure du Sucre, a long Creole lunch, a spa afternoon or Pamplemousses Botanical Garden in light showers. Avoid hiking, river swimming and canyoning during heavy rainfall, when conditions change quickly.

Is Mauritius worth visiting during rainy season?

For most travellers, yes. Summer brings the warmest sea of the year, the longest days and a green landscape, alongside higher humidity, more rain and cyclone-season overlap. Choose the west or north coast, keep excursions flexible, and book weather-dependent activities early in your stay.

Is Mauritius rainy season cheaper?

Sometimes, but pricing follows school holidays rather than rainfall. December and early January are the most expensive weeks of the year despite being wet, while late January through March is typically the quietest and best-value stretch. July and August are also peak, and those are dry-season months.

Why does my weather app show rain every day in Mauritius?

Because a rain icon usually signals the possibility of showers somewhere in the forecast area, not a prediction of all-day rain. Tropical convection is local, and an island-level symbol cannot show that your bay may stay dry. Read the detailed Mauritius Meteorological Services forecast bulletin instead.

Which month has the least rain in Mauritius?

October is the driest month island-wide, according to Mauritius Meteorological Services climatology. September and November are also comparatively dry — the northern station records about 49.5 mm in November across roughly 8 rain days, with the highest sunshine figure of the year at about 8.7 hours daily.

Which month has the most rain in Mauritius?

February and March are historically the wettest months island-wide. At the northern reference station, February records about 240 mm across roughly 16 rain days, with humidity around 84% — the highest of the year. January is close behind at about 206 mm.
