Madagascar experiences its hot, rainy season in December. This period marks the height of summer in the Southern Hemisphere, with temperatures varying significantly across the island due to its diverse topography. Coastal regions typically experience high humidity and average temperatures ranging from 25C to 30C (77F to 86F). The central highlands, however, tend to be cooler, with average temperatures around 20C to 25C (68F to 77F). Rainfall is abundant throughout much of the country, although the western and southwestern regions remain drier. Cyclones are also a possibility during this month, particularly in coastal areas.
Understanding these climatic conditions is essential for planning activities such as travel, agriculture, and resource management. The heavy rainfall replenishes water sources vital for both human consumption and irrigation, supporting the country’s agricultural sector. However, the increased rainfall can also lead to flooding and landslides, posing risks to infrastructure and communities. Historically, December’s weather patterns have shaped the island’s biodiversity and cultural practices, influencing traditional farming methods and seasonal celebrations.
