Best months to visit
MayJuneJulyAugustSeptemberOctober
May to early December is the sweet spot: warm but dry, sea above 24 °C, no cyclone risk. June-September is the cool peak (T-shirt by day, light layer at night). January-March is hottest and wettest — beach holidays still work between rain bursts, but cyclone risk is non-trivial.
Best for
Beach
May to mid-December — sea 24-28 °C, lowest rainfall along the leeward NW coast (Trou aux Biches, Flic en Flac, Mont Choisy). August-September is breezier but bright.
Hiking
May to October — Black River Gorges and Le Morne are comfortable at 20-25 °C; July-August nights on the central plateau drop to 13-15 °C.
Sightseeing
May to November — Port Louis market, Pamplemousses gardens and the colonial estates are best at 22-27 °C with low rain risk.
Climate notes
- Hot wet summer (November-April): the Mascarene high pulls warm humid air across the island, with January-March averaging 130-220 mm rain per month and 28-30 °C daytime highs.
- Cool dry winter (May-October): the southeast trade winds dominate; rainfall on the leeward NW coast drops to 20-50 mm per month, and humidity is comfortable.
- Cyclone season (November-April, peak January-March): tropical cyclones in the southwest Indian Ocean threaten the island roughly once a year on average; modern forecasting gives 3-5 days warning.
- Trade-wind microclimates: the east coast (Belle Mare, Trou d'Eau Douce) is windier and 30-40 % wetter than the leeward west and northwest (Flic en Flac, Trou aux Biches).
- Mountain effect: the central plateau (Curepipe, around 550 m) is 4-5 °C cooler than the coast and noticeably wetter year-round.
- Strong UV: at 20° latitude the sun is intense almost year-round; UV index regularly hits 11-13 between October and March.

Regional notes
- NW and W coast (Port Louis, Trou aux Biches, Flic en Flac, Le Morne): leeward, drier and sunnier — the main resort belt.
- East coast (Belle Mare, Trou d'Eau Douce): windward, around 30-40 % more rain and stronger trade winds — better for kitesurfing, weaker for calm beach days.
- Central plateau (Curepipe, Floréal, around 500-600 m): noticeably cooler and wetter; locals use it as summer escape from coastal heat.
- South coast (Souillac, Le Morne): exposed to swell from the Roaring Forties — strong surf in winter; Le Morne is a world-class kitesurf spot June-September.
- Rodrigues (570 km east, separate climate): drier and cooler than mainland Mauritius, with stronger trade winds.
Frequently asked questions
When is the best time to visit Mauritius?
May to early December — outside cyclone season, with sea above 24 °C, low rain on the leeward west coast, and comfortable 22-28 °C daytime. September and October are particularly reliable for sun.
Is it safe to visit Mauritius during cyclone season?
Cyclone season runs November-April with peak risk January-March. Direct hits are rare (roughly once every 3-5 years on average) and modern forecasts give 3-5 days warning. Travel insurance with cyclone coverage is recommended; flights and resorts have well-rehearsed protocols.
Which side of Mauritius is sunniest?
The west and northwest leeward coast (Port Louis, Trou aux Biches, Flic en Flac, Le Morne) is consistently the driest and sunniest. The east coast catches the trade winds and gets noticeably more rain and wind year-round.
Can I swim in Mauritius in July?
Yes — the lagoon stays 23-25 °C in July-August, the coolest months. Many visitors find it refreshing rather than cold; coral reefs around the lagoon make snorkelling enjoyable in any season.
When is the best time to kitesurf at Le Morne?
June to September — strong, reliable southeast trade winds (15-25 knots) and dry conditions. November-April is gustier and quieter wind-wise, with frequent rain showers.
Is Mauritius hotter than the Maldives?
Slightly cooler. Mauritius sits at 20°S, far enough from the equator to have a real cool season (July averages 21 °C); the Maldives at 4°N stays 27-28 °C all year.
Does Mauritius get hurricanes from the Atlantic?
No. Mauritius lies in the southwest Indian Ocean — Atlantic hurricanes do not reach it. The Indian Ocean has its own cyclone basin, with peak activity January-March (austral summer).
What is the weather like in Mauritius in December?
Hot and humid — daytime 28-30 °C, nights around 23 °C, sea 27-28 °C. Expect short heavy showers most afternoons. Cyclone risk starts mid-month but is statistically lower than January-February.
Do I need a jacket for Mauritius in winter?
A light layer for evenings on the central plateau (Curepipe, Floréal) and on coastal terraces in July-August. Daytime is T-shirt weather everywhere.
