In Nosy Be (or Nossi-bé) the climate is tropical
, hot all year round, with a rainy and hotter season from November to April, and a dry season from May to October. The island is located off the northwest coast of Madagascar, in an area that in the austral summer months is affected by the hot and humid monsoon coming from the north-west, while in the austral winter the cooler and drier south-east trade winds prevail. The climate of the neighboring islands, such as Nosy Komba, Nosy Mitsio, Nosy Tanikely and Nosy Sakatia is similar.
In an average year, about 86 inches of rain
fall. In the rainiest months (December, January and February), the rains are very frequent, occurring almost daily, and can sometimes be torrential. On the contrary, at the height of the dry season, from June to September, showers are very rare; in May and October they are a bit more frequent, but generally not intense.
