Climate & when to go
Mauritius enjoys a typically tropical climate with year-round heat, although the southeast trade winds help it never to feel too muggy. The summer months are from December to April, when it can nevertheless be extremely humid, and the winter, such as it is, runs from May to November, and is cooler and drier.
The best months to visit Mauritius are May to early December. January and February, the peak cyclone months, are best avoided by water-sports enthusiasts and divers. Cyclones rarely hit Mauritius (although Rodrigues has suffered far more regularly than the mainland) but cyclones way out at sea can bring days of squally rain.
Coastal temperatures range between 25°C and 33°C in summer and between 18°C and 24°C in winter. On the plateau it will be some 5°C cooler. The highlands are also the wettest part of the island – it can rain here at any time of year, and even when it’s not raining the area can be cloaked in low-lying cloud.
When the winds are at their strongest in July and August it can be blustery on the east coast, though the breeze brings welcome relief in summer.
Apart from the Christmas-New Year peak, Mauritius doesn’t really have high and low seasons. The situation is more dependent on outside factors (such as the French school holidays, which cause a big increase in demand and prices in August).
