Benin: when to go?
tropical humide climate
Benin enjoys a humid tropical climate marked by two distinct seasons. The dry season extends from November to March, characterized by the harmattan, a dry wind from the Sahara that brings pleasant temperatures and clear skies. This is the ideal period to discover Porto-Novo, Cotonou and the historic sites of Abomey. The rainy season, from May to October, transforms the landscape into a lush paradise but can complicate travel, particularly to Pendjari National Park. The transition months (April and November) offer an interesting compromise with fewer tourists and still favorable conditions. For a first trip, absolutely prioritize December to February: perfect temperatures around 28°C, low humidity and maximum sunshine to fully enjoy the beaches of Grand-Popo and the colorful markets.
