Why Senegal rewards careful timing.
Senegal sits at the western edge of the Sahel, the transitional zone between Sahara and tropical West Africa. Climate variations are pronounced: the coast (Dakar, Saint-Louis) is moderated by Atlantic breezes (15–28°C); the interior (Tambacounda, Niokolo-Koba) is hotter (20–40°C); the south (Casamance) is more tropical and greener.
Dry season (November–May) is the headline tourism window. November and December are the cool dry start, temperatures 18–28°C, low humidity, comfortable. Harmattan winds arrive in December and continue through February, the Saharan trade winds carrying fine dust haze that reduces visibility, especially inland. The harmattan is uncomfortable but not trip-killing, most tourists adjust by visiting morning before haze peaks. March–May is the warm-and-pleasant heart of the dry season, temperatures climb to 25–32°C, harmattan ends, sea warming to 22–24°C.
Rainy season (June–October) is the off-season. Heaviest rains July–September. The country becomes lush green and birds breed; wildlife in Niokolo-Koba disperses; Sine-Saloum Delta birding peaks; Casamance becomes harder to access as roads flood. Hotel rates 30–50% off peak.
Best months overall: November–March for cool dry weather; March–May for warm pleasant beach trips; late October for the green-to-dry transition.
Music festivals are a major Senegal tourism reason:
- Saint-Louis Jazz Festival: typically late May, one of West Africa's biggest jazz events.
- Festival International de Jazz de Dakar: typically May.
- Magal de Touba (Mouride Sufi pilgrimage to Touba): typically September; major domestic event.
- Tabaski (Eid al-Adha): around May 27, 2026, major Muslim holiday with sheep slaughter.
- Eid al-Fitr: March 19–20, 2026.
- Independence Day: April 4.
