What is the best time to visit Mauritius for good weather?

May to November is the best overall period for weather in Mauritius. The island is cooler, drier and less humid than during the summer months. June to September is peak season with the most reliable sunshine, while May, September and October offer similar conditions with fewer crowds and often lower accommodation prices.

Does Mauritius have a rainy season?

Yes. The rainy season runs roughly from November to April, with the heaviest rainfall in January, February and March. The east coast and central plateau receive the most rain. The west coast (Flic en Flac, Tamarin) and north coast (Grand Baie) are significantly drier due to the island's topography.

When is cyclone season in Mauritius?

Cyclone season in Mauritius runs from approximately November to April, with the highest risk in January, February and March. The Mauritius Meteorological Services issues official cyclone warnings (Class 1 to Class 4). Schools and most businesses close from Class 2 warnings onward.

What is the weather like in Port Louis?

Port Louis is the hottest area in Mauritius during summer, regularly reaching 34°C to 36°C in January and February due to its sheltered valley position. In winter (May to October), temperatures are comfortable at around 22°C to 26°C. Rainfall in Port Louis is moderate compared to the east coast and the plateau.

What is the weather like in Flic en Flac?

Flic en Flac on the west coast is one of the driest and sunniest areas of Mauritius. It sits in the rain shadow of the central mountains, so it receives less rainfall than the east coast even in summer. In winter, the west coast often stays sunny in the afternoon when the east coast is overcast. The lagoon is calm and sheltered year-round.

What is the weather like in Grand Baie?

Grand Baie on the north coast has a dry, warm and sheltered climate. It is one of the lowest-rainfall areas on the island, averaging around 900 mm to 1,000 mm per year. The lagoon is calm and swimmable year-round, and the area is generally sunny even in winter.

How hot does Mauritius get in summer?

Coastal areas in Mauritius typically reach 29°C to 33°C in summer (December to February), with Port Louis occasionally hitting 36°C. Humidity is high, which makes it feel hotter. The central plateau is cooler, usually 4°C to 6°C below sea-level temperatures.

How cold does Mauritius get in winter?

Mauritius does not get cold by global standards, but winter nights on the central plateau (Curepipe, Vacoas) can drop to 14°C or 15°C in June and July. Coastal areas stay warmer, typically 18°C to 22°C at night. A light jacket or fleece is useful for evenings during the cooler months.

Where can I check today's weather in Mauritius?

The official source for Mauritius weather forecasts, cyclone bulletins and marine conditions is the Mauritius Meteorological Services at metservice.intnet.mu. Weather apps such as Windy or Weather Underground can provide more localised readings from individual weather stations across the island.

Is the east coast or west coast better for beach weather in winter?

The west coast (Flic en Flac, Tamarin) and north coast (Grand Baie) are generally better for beach weather in winter. The southeast trade winds blow directly onto the east coast in winter, making seas choppier and sometimes bringing overcast skies. The west coast faces away from the prevailing winds and typically stays calmer and sunnier.

Mauritius Weather Guide: Month by Month

What Is the Weather Like in Mauritius?

Mauritius has a tropical climate with two main seasons: a warm, humid summer from November to April and a cooler, drier winter from May to October. Temperatures range from around 17°C in the coolest winter nights to 34°C on the hottest summer days. The island receives most of its rainfall between January and March, which also coincides with the cyclone season. For most visitors and residents, the best weather falls between May and November, when skies are clear, humidity drops, and the southeast trade winds keep things comfortable.

The Two Seasons of Mauritius

Summer (November to April): Warm, Humid and Wet

Summer in Mauritius is hot and sticky. Coastal areas like Grand Baie and Flic en Flac sit at around 28°C to 32°C during the day, while inland areas and the central plateau can feel noticeably cooler. Humidity climbs above 80% in January and February, which makes the heat feel heavier than the thermometer suggests.

This is also cyclone season. Mauritius sits in the South-West Indian Ocean cyclone belt, and the island can be affected by tropical storms between December and April. Not every year brings a direct hit, but cyclone warnings are issued several times most seasons. The Mauritius Meteorological Services monitors all systems and issues alerts ranging from Class 1 (a distant threat) to Class 4 (a severe cyclone with winds above 120 km/h). Schools and offices close during Class 2 warnings and above.

Rainfall is heaviest on the east coast and the central plateau, where towns like Curepipe and Mahebourg can receive more than 3,000 mm of rain per year. The west coast, including Flic en Flac and Tamarin, sits in a rain shadow and stays drier even in summer, which is one reason the west coast is popular with beach-goers year-round.

Winter (May to October): Cool, Dry and Clear

Winter is the season most visitors prefer. The southeast trade winds blow steadily, temperatures on the coast settle between 22°C and 27°C, and the sky is reliably blue. Humidity falls, making outdoor activity far more comfortable. The central plateau and the south coast can feel genuinely chilly at night in June and July, occasionally dipping below 15°C in elevated areas like Vacoas or Curepipe. Pack a light jacket if you plan to spend evenings outdoors in those areas.

The east and south coasts get stronger trade winds in winter, which makes them popular with kitesurfers and windsurfers but can churn up the sea for casual swimmers. The north coast around Grand Baie and the west coast around Flic en Flac are more sheltered and calmer for swimming during these months.

Month-by-Month Weather Breakdown

January and February

The hottest and wettest months of the year. Expect temperatures of 29°C to 33°C on the coast, frequent afternoon downpours, and peak cyclone risk. The sea is warm (around 28°C), which is great for snorkelling when the weather cooperates. Beaches on the west coast remain the most sheltered option during unsettled spells.

March and April

The tail end of summer. Rain eases gradually, humidity starts to drop, and the cyclone risk falls sharply after mid-March. April is a transitional month with pleasant temperatures (25°C to 30°C) and increasingly clear skies. Many locals consider April one of the nicest months to be outdoors.

May and June

The start of winter. Temperatures cool to 22°C to 27°C on the coast. The trade winds pick up, seas are clearer, and visibility for diving improves significantly. Whale watching season begins in June, when humpback whales migrate through Mauritian waters. Evenings can be cool enough to need a layer.

July and August

Peak tourist season and the coolest months. Daytime temperatures on the coast hover around 22°C to 25°C. The central plateau can drop to 14°C or 15°C at night. The sea is calmer on the north and west coasts, and the trade winds are at their strongest on the east coast. This is the busiest period for hotels and flights, so prices reflect that.

September and October

Winter transitions back to spring. Temperatures rise gently to 25°C to 28°C, winds ease, and the island feels less crowded than July and August. October is widely regarded as one of the most balanced months: warm enough to swim comfortably, dry enough for outdoor activities, and quieter than peak season.

November and December

Summer returns. Temperatures climb back above 28°C, humidity rises, and the first tropical depressions of the new cyclone season can form from November onward. December is festive and busy, with Christmas and New Year drawing both local celebrations and international visitors. Book accommodation early if you plan to visit over the holiday period.

Weather in Port Louis

Port Louis, the capital, sits on the northwest coast in a natural amphitheatre of hills. This geography traps heat and reduces the sea breeze that cools coastal towns further north or west. In summer, Port Louis is consistently one of the hottest spots on the island, with temperatures frequently reaching 34°C to 36°C in January and February. The surrounding hills also funnel and amplify afternoon heat, making the city feel hotter than weather station readings suggest.

In winter, Port Louis is more comfortable: temperatures settle around 22°C to 26°C during the day, and the city benefits from its low elevation compared to the plateau towns. Rainfall in Port Louis is moderate compared to the east coast and the plateau, though sudden heavy showers can cause short-term flooding in lower-lying parts of the city during summer.

If you are working or visiting in Port Louis during summer months, plan outdoor activities for the morning. By midday, the heat in the central business district and the waterfront area can be intense.

Weather in Grand Baie

Grand Baie, on the north coast, enjoys some of the most stable and pleasant weather on the island. Its position on the sheltered northern tip means it misses the worst of the southeast trade winds in winter and avoids the heaviest rainfall that affects the east coast and plateau in summer.

In winter, Grand Baie is warm and breezy, with sea temperatures around 24°C to 25°C, making it ideal for water sports and beach days. In summer, it is hot and humid like the rest of the island, but the lagoon remains calm and swimmable. Grand Baie is one of the driest areas of Mauritius, averaging around 900 mm to 1,000 mm of rain per year, compared to over 3,000 mm on the eastern plateau.

This combination of low rainfall, calm lagoon and year-round warmth makes Grand Baie the most consistently popular tourist area on the island.

Weather in Flic en Flac

Flic en Flac, on the west coast, shares many of the same advantages as Grand Baie. It sits in the rain shadow of the Rempart and Tourelle mountains, which block much of the moisture-laden southeast trade winds before they reach the west coast. The result is a drier, sunnier microclimate compared to the east and the plateau.

In summer, Flic en Flac is warm and humid but receives noticeably less rain than areas like Mahebourg or Curepipe. In winter, the beach benefits from afternoon sunshine even when the east coast is overcast, because the trade winds blow from the southeast and the west coast faces away from the prevailing weather. Sunsets over the lagoon at Flic en Flac are a reliable draw year-round.

Sea conditions at Flic en Flac are generally calm, protected by the outer reef. Water temperature stays above 24°C for most of the year, dipping slightly in July and August.

Checking Today's Weather in Mauritius

For current and forecast conditions, the Mauritius Meteorological Services (metservice.intnet.mu) is the official source. It publishes daily forecasts, cyclone bulletins, UV index readings and tide tables. The service also issues marine forecasts for boaters and fishermen. For real-time conditions in specific areas, weather apps that pull from local stations (such as Windy or Weather Underground) can give more granular readings than a single island-wide forecast.

During the cyclone season, check the Meteorological Services site daily if you are planning outdoor or marine activities. Cyclone warnings can be issued with relatively short notice, and conditions can deteriorate quickly.

Best Time to Visit Mauritius

The clearest answer: May to November is the best overall window, with June to September being the peak of good weather. Within that window:

May, September and October offer the best balance of good weather, lower crowds and more competitive accommodation prices compared to July and August.
July and August are the most popular months, with the best weather but also the highest hotel rates and the busiest beaches.
December to April suits visitors who do not mind humidity and the occasional heavy shower, want to experience the festive season, or are specifically interested in summer water sports and warm sea temperatures. Just monitor cyclone bulletins.

For diving, the clearest water and best visibility falls between April and November. For whale watching, June to October is the season. For kitesurfing on the east coast, June to September brings the strongest and most consistent winds.

Regional Weather Differences: A Quick Summary

Mauritius is a small island (roughly 65 km by 45 km) but its terrain creates meaningful microclimates:

North coast (Grand Baie, Pereybere): Dry, sheltered, calm seas, reliable sunshine year-round.
West coast (Flic en Flac, Tamarin, Black River): Rain shadow effect, afternoon sun in winter, excellent for beach days even when other areas are overcast.
East coast (Belle Mare, Trou d'Eau Douce, Mahebourg): Windier in winter, more rainfall, but stunning beaches and clearer water for snorkelling.
Central plateau (Curepipe, Vacoas, Quatre Bornes): Cooler and wetter year-round, often misty or rainy when the coast is sunny. Temperatures can be 4°C to 6°C lower than sea level.
Port Louis: Hottest area in summer due to the bowl-shaped valley geography; moderate rainfall.
South coast (Le Morne, Souillac): Dramatic scenery, stronger winds, rougher seas in winter, beautiful in summer.

Practical Tips for Each Season

Summer visits: Pack light, breathable clothing, a compact umbrella or light rain jacket, and high-SPF sunscreen. UV index in Mauritius regularly hits 11 or above in summer, which is extreme. Schedule beach time for mornings and late afternoons. If a cyclone warning is issued, follow official guidance and stay indoors during Class 2 and above.

Winter visits: Bring a light fleece or cardigan for evenings, especially if you are staying in the central plateau or visiting in June or July. Sunscreen is still essential: even in winter, the UV index in Mauritius can reach 8 to 10 on clear days. The sea is cooler (around 23°C to 24°C) but still comfortable for swimming without a wetsuit for most people.

Year-round: The sun rises early (around 5:30 am in summer, 6:00 am in winter) and sets early (around 6:30 pm in summer, 5:45 pm in winter). Plan outdoor activities accordingly.
