Sierra Leone weather overview

Sierra Leone in West Africa has an Atlantic coastline and an inland plain leading to hill country so the further inland you go, the hotter and drier the weather. Humidity is unpleasantly high on the coast and, during the very heavy rainy season between May and November, this combines with heavy cloud to make life very uncomfortable.

Matters improve during the dry season when sunny, bright weather predominates and the Harmattan desert winds blow. Temperatures are high all year.
