Overview of Nosy Be’s Winter Climate
Nosy Be sits off Madagascar’s northwest coast in the Indian Ocean. Its tropical climate shapes the weather, with warm temperatures all year.
Rainfall and humidity patterns shift with the seasons. You’ll notice a real difference between the wet and dry periods.
Location and Geography of Nosy Be
Nosy Be is about 8 kilometers off Madagascar’s northwest coast, right in the Mozambique Channel. Because it’s near the equator, the island stays warm and humid.
The island covers roughly 320 square kilometers. Volcanic hills, coastal plains, and dense forests all shape local weather.
Higher areas stay a bit cooler. Coastal zones get stronger sea breezes.
The Indian Ocean moderates temperatures, keeping daytime highs steady between 27 °C and 30 °C for most of the year. The ocean’s warmth also increases humidity, which affects rainfall patterns.
Nosy Be’s small size means you won’t find big regional differences in climate. Still, sheltered bays and inland valleys can feel more humid than open coastal areas.
Location matters if you’re planning activities during winter.

Winter Weather Compared to Other Regions in Madagascar
Winter in Madagascar looks different depending on where you go. Coastal areas, highland plateaus, and northern islands all bring their own mix of temperature, rain, and humidity.

Beach visits and boat trips just feel better when you’re not sweating buckets, right? Unlike those inland spots where nights can get a bit chilly, Nosy Be almost never drops below 70°F.
You won’t need to pack heavy layers, and evenings are perfect for eating outside or strolling along the coast. The sea temperature is another big plus.
