Weather & seasons
Mauritius is in the Southern Hemisphere, so seasons run opposite to the Maldives: May–November is the cooler, drier winter (SE trade winds, about 20–26°C, one of the main tourist peaks) and December–April is the hot, humid summer (about 28–33°C, the warmest water, with January–March the peak cyclone risk). The north and west coasts are sheltered and calm; the east and south face the wind, with stronger breezes and swell in winter. Peak prices (Christmas/New Year, the July–August European holidays) do not always match the best weather. Season boundaries shift a little each year; below is the general pattern.
Month 1Wet season
Hot, wet and the peak of cyclone risk — only for flexible travellers chasing low prices.
- Weather
- High summer: hot, humid and showery, with the most concentrated rain of the year. This is also the core of the cyclone season, so a tropical storm can disrupt plans.
- Sea
- Warm water (about 28°C), but rain and swell can stir up the lagoon and cut visibility; the west and north are usually calmer than the east and south.
- Crowds & price
- Just after the Christmas/New Year peak, prices ease; low-season deals start to appear.
- Good for
- Spa, pool and beach time between showers; choose flexible bookings and travel insurance that covers weather disruption.
Month 2Wet season
Cheap but wet, with real cyclone risk — a bet on the weather.
- Weather
- Still the hottest and most humid stretch, with frequent heavy showers; cyclone risk stays high, especially in February.
- Sea
- Warm water but often choppy or murky after rain; west-coast lagoons are the most sheltered.

- Weather
- Late summer: still hot and humid, with rain and cyclone risk starting to ease towards month-end.
- Sea

A few commonly asked windows
- · Value sweet spot: May and September–October — either end of the winter season, settled weather before prices peak or after they ease.

- · Warmest water for swimming: December–April; but January–March is peak cyclone risk, so keep plans flexible.
- · Most expensive: Christmas/New Year and the July–August European holidays. Cheapest: January–March and parts of May–June.
