Eastern Coast
The eastern region, including Toamasina and Tolagnaro, has a hot, humid tropical rainforest climate year-round. Annual rainfall reaches 2000-3800 mm, concentrated in the November-April wet season, with average temperatures around 24°C. High humidity and frequent rains make it lush but prone to cyclones. Summers are steamy, winters milder but still warm. Expats enjoy biodiversity but should expect mold and flooding risks during peak rains.[1][3]
Oppressively humid and lush, with persistent rain creating a vibrant, misty tropical paradise ideal for nature lovers but challenging for dry-climate preferences.
Central Highlands
Central areas like Antananarivo and Fianarantsoa feature a mild tropical plateau climate with annual rainfall of 1000-2000 mm, mainly April-September. Average temperatures hover at 18°C, cooling to 5-15°C at night in winter (June-September). Day-night swings are significant, requiring warm layers. Summers warm to 28-30°C.
