May is a transitional month: temperatures remain high, and the southern parts of the country may see the first convective showers late in the month. Humidity starts to increase where rains begin, making conditions feel warmer. Road conditions start to change in low-lying areas as terraces and tracks become damp.

Where to Go in Niger in May
The Sahara - Northern Desert
Ténéré, Bilma, Dirkou
May ramps temperature further and the desert’s surface becomes energetically hot; the air is dry and oppressive by mid-day with regular mirages on long straightouts toward the Ténéré. This is the most challenging month for overland travel in northern Niger - many operators suspend long crossings and flights to small desert strips can be affected by thermic turbulence. Plan short, well-supported excursions with experienced guides, and avoid solo travel; nights remain a relief, cooling enough for sleep with light bedding.
Aïr Mountains and Azawagh Basin
Agadez, Iferouane
May turns intensely hot across the lower basins; the Aïr high points offer some respite but desert heat makes midday activity uncomfortable and dust storms become more common. Fuel reliability and mechanical preparedness are crucial - breakdowns are more serious here because of remote distances. If you’re focused on culture, plan market visits for mornings and evenings and avoid strenuous hikes in the heat.
Central Sahel
Agadez-Tahoua-Zinder corridor
May brings intense heat with frequent hazy skies; winds stir persistent dust that can coat vehicles and reduce visibility on long roads around Agadez and Tahoua. The Sahelian short rains have not yet arrived here, so water remains scarce and some seasonal tracks start to deteriorate under hot winds. If you must travel, focus on early-morning market visits, carry plenty of fluids, and ensure your vehicle has air filtration and cooling checks completed.
Niger River Valley and Southwest
Niamey, Tillabéri, Dosso, W National Park
May is very hot and humid by the river compared with the north; the Niger’s banks bake under persistent sun while humidity edges upward, presaging the approaching rains. Many daily locals rest during the hottest hours and river excursions are limited to early morning and late afternoon. Travelers should prepare for heat stress, ensure drinking water, and expect fewer services in rural lodges that may close during peak heat.
Lake Chad Basin and the Southeast
Diffa, N’guigmi, Lake Chad shores
May continues the extreme pre-monsoon heat, though humidity may begin to creep up near remaining shallow pools - these attract birds and pastoralists to scant grazing. This month is not ideal for extended itineraries as services are limited and the risk of heat-related illness is higher. If you must travel, keep itineraries short, maintain shade and hydration routines, and rely on experienced local guides for routes around flooded or silted channels.
