The climate of Mauritius

Mauritius has a mainly tropical climate. Various microclimates exist on the island based on exposure, altitude, and distance from the sea. Mauritius is an island country in the Indian Ocean, 1200 miles southeast of Africa, and 700 miles east of Madagascar. Persistent trade winds and the island's topography create a broad climatic division into windward and leeward zones. The windward eastern and southern slopes have a tropical rainforest climate (Köppen climate classification Af) and show a marked increase in cloudiness and rainfall. The sheltered leeward side experiences a tropical savanna climate (Köppen Aw), with a significant decrease in cloud cover and rainfall. The central plateau has a humid subtropical climate (Köppen Cf variations), with no marked dry season. The proximity to large bodies of water, tropical latitudes, and the southeast trade winds chiefly influence the climate.

Mauritius is a tropical island of volcanic origin, 20°S of the equator. Several outlying islands, including Agalega, Rodrigues, and Saint Brandon, lie within the main island's distance. The pear-shaped island is 38 miles long and 28 miles wide and consists of a ring of peaks that enclose a central plateau. The landscape consists of a small coastal plain and a central plateau, which rises from 300 meters in the north to 600 meters in the southwest. The central plateau is cooler than the coast and receives almost twice the rainfall. The eastern part of the island is colder than the rest of the country due to prevailing southeast trade winds. Coral reefs surround the island to pose navigation hazards. Piton de la Petite Riviere Noire is the highest point in Mauritius at 828 meters above sea level.
