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]
