Madagascar has 5 climatic zones, which follow the physical geography of the island by differentiating the mild Highlands, the hot and dry western regions, the rainy and the eastern coastal regions under the influence of trade winds, the hot and wet North, and the semi-arid South.
The eastern part of Madagascar receives much rain, brought onshore by southeastern trade winds, which are forced to rise and drop moisture as they meet the eastern escarpment; annual precipitation in some places exceeds 120 inches.
The central plateau gets considerably less moisture, and arid areas in the south and southwest receive less than 15 inches of precipitation per year. Most of the rain falls from November to April.
The coastal regions generally are hot throughout the year. The central plateau has a temperate climate, with warm summers and cool winters.
The average temperature range in Antananarivo on the plateau is 16C to 26C (61F to 79F) in January and 9C to 20C (48F to 68F) in July.
The dry season or the southern winter is from April to October, and summer is from November to March. Most travellers to Madagascar choose to visit between the April to October dry season, though travel in November and December is also generally fine. January to March is cyclone season. Book early for Christmas, New Year, Easter and French school holiday periods due to limited availability of accommodation and high demand.
