The climate of Mauritius is tropical with no dry season, although it is slightly less wet from August to November.
From November through to April daytime temperatures are warm to hot on the coast and slightly cooler at higher elevations. At sea level heat and humidity can be oppressive and November to April is also the cloudiest and wettest part of the year. Heavy tropical downpours are common during the afternoon, particularly over high ground and in the east, especially from January to March. However even at this time of year periods of rain are relatively short-lived and there is still a great deal of sunshine. Between January and March the probability of a cyclone passing Mauritius is also at its greatest. However in practice there is usually only one a year that comes anywhere close to the island.
From April to November temperatures are slightly lower with July and August being the coolest months.
At higher elevations temperatures at night may fall as low as 15°C (59°F) and rise to 22°C (72°F) during the day.
The coast is usually 2 or 3 degrees warmer with a fairly constant breeze from the south-east.
