Mauritius climate overview

Known by many as home to the now extinct dodo, a large flightless bird, Mauritius is today not only one of the main commercial centres of the Indian Ocean, but also one of its most popular tourist destinations.

Despite being technically part of Africa most of the population are of Indian origin, descendants of those who came over in the mid-to-late 19th century to work on the sugar plantations.

Mauritius had no indigenous population before the arrival of the Portuguese in the 16th century. Today it is a vibrant society noted for its British political institutions, French architecture and blend of Indian, Chinese and Creole culture.

The island of Mauritius and its neighbour Reunion are both part of an ancient undersea volcanic chain. However unlike Reunion, Mauritius is no longer active and most of the evidence of volcanic activity has long since eroded away, with the exception of the odd pillar of basalt still pointing skywards.

Mauritius consists of a broken ring of mountain ranges encircling a central tableland that slopes upwards towards the south of the island. Coastal plains surround the plateau, except in the southwest where the plateau drops off steeply into the sea.

Coral reefs almost completely surround the island providing material for the white sand beaches such as at Grand Baie for which Mauritius is so famous and which are one of the islands main tourist attractions. Inland the vegetation is lush and green. Plantations of sugarcane and tea dominate the rolling countryside.

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.
