From late July to early September, it is the best season to visit Benin. It is dry and cool around this time when travelers can enjoy this otherwise hot and humid country. From September to November there is a short spell of rainy season. The main rainfall occurs in the months from April to July.
The period from December to March should be avoided. A dry Sahara wind known as Harmattan blows around this time which covers almost the entire Benin with a thin cloud of dust.
