Climate
The climate is tropical along the coast, temperate inland, and arid in the south. The weather is dominated by the southeastern trade winds that originate in the Indian Ocean anticyclone, a centre of high atmospheric pressure that seasonally changes its position over the ocean. Madagascar has two seasons: a hot, rainy season from November to April, and a cooler, dry season from May to October. There is, however, great variation in climate owing to elevation and position relative to dominant winds. The east coast has a sub-equatorial climate and, being most directly exposed to the trade winds, has the heaviest rainfall, averaging as much as 3,500 mm (137.8 in) annually. This region is notorious not only for a hot, humid climate in which tropical fevers are endemic but also for the destructive cyclones that occur during the rainy season, coming in principally from the direction of the Mascarene Islands. Because rain clouds discharge much of their moisture east of the highest elevations on the island, the central highlands are appreciably drier and, owing to the altitude, also cooler. Thunderstorms are common during the rainy season in the central highlands, and lightning is a serious hazard.
Antananarivo receives practically all of its average annual 1,400 mm (55.1 in) of rainfall between November and April. The dry season is pleasant and sunny, although somewhat chilly, especially in the mornings. Although frosts are rare in Antananarivo, they are common at higher elevations.
