When to Visit Senegal

Senegal sits at the westernmost point of Africa, and its weather is shaped by two forces that take turns dominating the calendar: the Saharan harmattan and the Atlantic monsoon. The result is a climate of two clear seasons rather than four, with a long dry stretch running roughly from November through May and a concentrated rainy period peaking in August and September. What makes Senegal distinctive is how moderate those swings are. Dakar's coastal position keeps temperatures from going extreme in either direction. You're looking at highs of around 25°C (77°F) in the cool dry months climbing to 31°C (88°F) by late October, which is warm but not punishing by West African standards. The humidity stays remarkably stable at around 70 percent year-round. The real variation between seasons is rainfall and cloud cover, not some dramatic shift in heat. During the dry season, the harmattan wind occasionally pushes down from the Sahara, carrying fine dust that can turn the sky a hazy orange and make distant landmarks disappear. This is most noticeable in January and February, and while it looks dramatic, it's more of a nuisance than a hardship. The rest of the dry season tends to bring clear blue skies and pleasant breezes off the Atlantic, along the Petite Côte and the beaches around Mbour and Saly. By June, you can feel the character of the air begin to shift. It gets heavier and more charged, the way the atmosphere does before a season turns. The wet season in Senegal tends to concentrate its rainfall into afternoon and evening downpours rather than all-day grey drizzle. July and August bring the bulk of it, with August alone averaging around 155mm of rain. But mornings often stay clear and the showers can pass quickly. September is similar. The upside: everything turns green, the landscape is lush in a way that surprises first-time visitors who assumed Senegal was purely Sahel scrubland, and the crowds thin out considerably.
