The seasonal pattern for Mauritius — what each stretch of the year tends to bring, and what to plan around. Guidance, not a forecast.
Seasonal pattern, not a forecast — conditions vary; verify tides, weather and visibility locally before you go.
Mauritius runs on two trade regimes. The south-east trades, broadly May to September, bring cooler, breezier and generally drier weather, with the clearest water on the sheltered west and north-west coasts while the east takes the wind. The warmer, more humid north-west monsoon, broadly November to March, brings lighter winds and heavier rain, and the transition months in between often give the calmest, clearest water of the year. The island sits in the South Indian Ocean cyclone belt, so tropical weather is possible in the wetter half of the year, and water stays warm enough for a rashguard or thin shorty most of the year. Tides matter more than most visitors expect, because so much of the snorkeling is shallow lagoon: some sites change character completely between high and low water, and the reef flat under Le Morne and parts of Flic en Flac can be barely awash at low tide. Check the tide table, read the day's forecast, and follow the local flags and lifeguard advice.

A single high island in the western Indian Ocean, ringed by a shallow lagoon and by one of the region's older protected marine areas. The snorkeling here is lagoon and sheltered-bay water rather than a barrier reef: Blue Bay Marine Park carries the best coral, while Trou aux Biches, Flic en Flac and the Île aux Cerfs lagoon are easy, calm, wade-in mornings. Come for warm, clear, genuinely accessible water — and be clear-eyed that these reefs have taken warming hits too.
