Where to Go in Burkina Faso in May
Sahel / Northern Burkina
Dori, Djibo, Gorom‑Gorom
Rains often arrive in June in the Sahel but the seasonal onset is variable; May is when showers can first be felt in the southern fringe but the true Sahelian rains usually begin in June. When the rains start the countryside quickly greens and short‑lived ponds appear; even small storms can turn tracks slippery and cut village access. Early in the wet season mosquitos surge, so bring repellant and a treated net if camping; some remote lodges close until roads firm up.
Central Plateau & Ouagadougou
capital region
By May the first reliable showers reach the southern edge of the plateau and tall grasses begin to green, though Ouagadougou often sees intermittent storms rather than sustained rains. Even a few heavy downpours can soften the dusty roads and create vivid evening humidity - good for photographers as the light shifts. Bring a light rain jacket and plan for occasional traffic disruptions after heavy showers; mosquitoes begin to increase in the evenings.
West & Hauts‑Bassins
Bobo‑Dioulasso, Banfora approach
By May the western plains see the onset of regular rains, greening the landscape and swelling the Comoe tributaries near Banfora; watery lanes can make routes toward waterfalls slippery. Showers tend to fall in the afternoon and evening, breaking the heat and improving rural vistas for photography. Mosquito presence grows and simple bush camping becomes more insect‑focused - take repellant and a waterproof tent if you plan overnight field trips.
Southwest Cascades & Banfora
Karfiguéla falls, Sindou
May is the true start of the rainy season in the southwest: short, heavy storms transform the landscape and the tributaries feeding Karfiguéla begin to show life. Water levels rise quickly after the first sustained rains, and the falls become photogenic; however, some walking tracks into the gallery forest may become slippery. Mosquitoes increase and rural campsites can be soggy, so bring repellant and waterproof gear.
East & Gourma Plains
Fada N’Gourma, Pama, Arly area
May marks the beginning of the rainy season in the east, often arriving later and more erratically than in the southwest; thunderstorms become more frequent and the first flush of green appears. Pools and temporary pans refill, attracting wildlife back to traditional watering spots and improving birdwatching chances. Some secondary roads become unreliable after heavy rains, so plan for alternate routes and expect more mosquitoes in the evenings.
Events & Festivals in May
