The climate of Senegal is tropical, differentiated in two seasons based on the rains. During the dry and hot season, which corresponds to the months between November and June, along the coasts, the trade winds blow which bring refreshment. While in the interior of the country, harmattan blows, a hot and dry wind from the desert that carries fine dust and sand. The driest months are those between February and April.
In the months between July and October the southwest monsoon blows. This monsoon brings the tropical rainy season across the country. However, these rains are of greater intensity in the south of the country, while they decrease significantly towards the north.
Within these two seasons there are also two intermediate periods. The first between November and January with mild temperatures and rare rains. While the second occurs between April and June and brings high temperatures and humidity.
In the southern areas of the country, the rainiest ones, rainfall reaches values around 1,500 mm per year. While in the capital Dakar the average annual rainfall is around 500 mm. Finally, in the far north, in the city of Saint-Louis, there is less than 300 mm of rain per year.
Throughout Senegal the hottest months are between June and November. Along the coast there are average maximum temperatures of about 30 ° C, while in the interior it can also reach 40 ° C. The coolest months are those between January and April, when, along the coast, the average maximum temperatures reach 25 ° C.
The sea water temperature varies between 20 ° C in March and 28 ° C in the months between August and October.
