The climate in Benin is tropical because of its location near the equator. There are only small temperature fluctuations in the course of the day and year. The climate can be divided into two zones due to different rainy seasons. In the south of the country, i.e. from the coast to about 200 kilometres inland, the climate is hot and humid with two dry seasons and two rainy seasons. Average temperatures throughout the year are between 26 and 32 degrees Celsius. The rainy seasons last from April to mid-July and from mid-September to November. In between there is a dry season. In northern Benin there is only one rainy season from the beginning of June to September. During the dry season from November to May a hot and dusty wind blows from the Sahara into the region. The average maximum values are usually between 30 and 38 degrees. The temperature differences from day to night are greater than in the south of the country.
No matter if you want to travel to the south or north of Benin, you should choose the respective dry season. For the north we recommend the months November to February, for the south December to March as well as July and August.
