When to Visit Senegal

Senegal sits on the westernmost point of the African continent, and that geography shapes everything about its climate. The country falls squarely within the Sahel and tropical savanna zones, which means it operates on a two-season rhythm rather than the four-season cycle familiar to European or North American travelers. From roughly November through May, the dry season dominates, bringing clear skies, low humidity, and virtually zero rainfall, along the coast around Dakar. Then from June through October, the wet season rolls in with the West African monsoon, locally called the hivernage, delivering the vast majority of the year's rain in intense, often dramatic downpours. Measured in Dakar, annual rainfall concentrates almost entirely between July and September, with August alone accounting for 155 mm of the total. What makes Senegal's weather distinctive, though, is the moderating influence of the Atlantic Ocean along the western coast. Dakar, perched on the Cap-Vert peninsula, stays remarkably mild by West African standards during the dry season, with highs hovering around 25°C (77°F) from December through May. Head inland toward Tambacounda or the Casamance region, and temperatures climb considerably, often exceeding 40°C during the late dry season. The Harmattan wind, a dry, dusty flow off the Sahara, tends to affect northern and interior Senegal most noticeably between December and February, sometimes reducing visibility and leaving a fine layer of sand on everything. Coastal areas feel it less. But you might notice hazy skies on certain mornings even in Dakar. The transition months of June and October deserve particular attention. June marks the uneasy start of the rains, when humidity climbs sharply but consistent downpours haven't yet arrived, creating a muggy, waiting quality to the air. October reverses this, with the rains tapering off but heat lingering at its annual peak. For whatever reason, October is often the month visitors find most uncomfortable along the coast, with Dakar recording its highest average temperatures of 31°C (87°F) alongside humidity still sitting at 78%.
