Mauritius is a year-round destination, with a mild tropical climate and up to eight hours of sunshine each day, but weather is still a consideration when deciding the best time to visit, where to go and what to do on Mauritius.
The island has two seasons: a hot, wet and humid summer (October to April), with a slight risk of cyclones from January to March, and a warm, dry winter (May to September). Average temperatures range from around 25°C in summer to 20°C in winter. Average annual rainfall is 2010mm, most of which falls in summer.
As Mauritius is best known for winter sun, the peak season for tourism is from October to April and low season runs from May to September. Rodrigues’ peak tourist seasons are from the end of November to February, around Easter in April and from the end of June to August; outside of these times beach restaurants are often closed and only a few tables d’hôtes are open. The cooler, drier months from June to September, with fewer mosquitos, are good for outdoor activities; clear, calm and warm waters from November to April are ideal for diving; the best deep-sea fishing is from October to April; and surfing conditions are at their best from June to August.
Note that the west and north coasts are warmer and drier than the east and south coasts. In the summer, the cooling southeast trade winds make the east coast pleasant and perfect for watersports, but the south and east can be chilly and windy in winter. The north and west coasts are more sheltered in winter, meanwhile, but can get stiflingly hot and humid in summer. Most rain falls in the highlands, with Curepipe the rainiest of the inland towns.
