Climate & Weather Guide · SenegalClimate & Weather Guide in Senegal
Climate zones, seasonal temperatures, rainfall patterns, and best travel times
Senegal has a hot Sahelian-to-tropical climate shaped by latitude, the Atlantic coast, and a strong north-south rainfall gradient. The country is mostly hot year-round, with coastal areas moderated by sea breezes and inland areas feeling hotter and drier. Most of Senegal falls under hot semi-arid or tropical savanna Köppen types, while the far north is drier and the south-west is wetter. For residents and expats, the main practical differences are humidity, length of the rainy season, and heat intensity rather than cold weather. The climate is generally favorable for year-round outdoor living, but water availability, dust in the north, and seasonal heavy rains in the south matter for daily life.

Regional Climate Variations
Northern Sahel and Ferlo
This is Senegal’s driest zone, stretching across the far north and interior north-east. It has a hot, dry feel for much of the year, with long sunny periods, dusty harmattan influences, and a short rainy season or very limited rainfall. Based on Senegal’s national climate pattern, annual precipitation here is around the lowest national values, near 250 mm, and temperatures remain high in both the dry and wet seasons.
Very hot, dry, and dusty for most of the year, with a short and unreliable wet season; best suited to residents who can tolerate heat, low humidity, and water constraints.
Central Groundnut Basin and Inland Plains
Central Senegal, including the main inland farming belt, is warmer and slightly more humid than the far north but still distinctly seasonal. Rain falls mainly during a single wet season, and the dry season is long and pronounced. This zone is a transition between the arid north and the wetter south, so residents experience intense heat, high sunshine, and modest but important summer rains.
Hot and sun-drenched with a strong dry season; comfortable for people who prefer warmth and low winter chill, but the dry months can feel harsh and water stress is a real concern.
Greater Dakar and the Atlantic Coast
The Dakar metropolitan area and nearby Atlantic coast are moderated by ocean breezes, making them more comfortable than inland Senegal. Temperatures are still warm, but the coast usually feels less extreme, especially during the hottest months. Rainfall is lower than in the south but higher than the far north, and humidity is more noticeable because of the maritime setting.
Warm, breezy, and relatively livable year-round, with coastal moderation that makes this the most appealing zone for expats seeking less extreme heat.
Southern Casamance
Casamance in the south is Senegal’s wettest and most tropical region, with a longer rainy season and greener landscapes. Annual precipitation can reach the upper national range, around 1,450 mm, and the climate feels more humid and lush than the rest of the country. The warm season is more oppressive because of moisture in the air, but the region is also the most fertile and visually green.
Hot, humid, and distinctly tropical, with the most reliable rainy season in Senegal; attractive for greenery and agriculture, but less comfortable for those sensitive to humidity.
Senegal is mostly hot, sunny, and seasonally dry, with a clear gradient from arid conditions in the north to humid tropical conditions in the south. For residents and expats, Dakar and the Atlantic coast are usually the most comfortable, while Casamance offers more greenery and rain, and the north is best suited to people who prefer dry heat.
