Climate of Mauritius
Country climate guideMauritius is a small volcanic island of about 2,000 square kilometres in the western Indian Ocean, roughly 20° south of the equator and some 2,000 kilometres off the coast of Africa. Its interior is a massif of hills and, further south, the steep ridges of the Black River gorge, so the island has a strong altitudinal gradient from the narrow coastal plain to ridges of about 900 metres. Ringed by a shallow shelf of coral reef, it has a tropical maritime climate of warm, humid weather and steady sea breezes.
Main climate types
The whole island falls into the tropical category, but with two distinct faces. Higher ground and the windward south-west are humid, with rain in every month, while the leeward north-west and north-east coasts are drier and sunnier. A montane type covers the central plateau, where altitude and trade-wind cloud hold temperatures down by 3 °C to 5 °C compared with the coast. There is no true dry season.
Temperatures
The range is narrow, because the surrounding sea stabilises it. Port Louis on the north-west coast averages about 23 °C in July and about 27 °C in January, while the central plateau sits about 3 °C cooler. Along the coast, highs are usually 28 °C to 30 °C and lows about 20 °C. The coldest weeks are July and August and the hottest February and March. Frost and snow are unknown at these latitudes.
Rainfall
Totals vary enormously over a short distance. The windward south-west, around Chamarel and the Black River, receives 2,000 mm to 2,500 mm a year, while the leeward and northern coasts receive only about 1,000 mm. Most rain falls between January and March, when the north-west monsoon is strongest, and the dry, clear months run from about May to October under the south-east trades. Cyclones, forming between November and May, can drop a month's rain in a day.
When to go
The best months are usually April to June and September to November, when heat and humidity are moderate and the trades keep the air fresh. January to March is the wettest and least comfortable period, and storm warnings are worth watching then.
