Climate of Niger
Country climate guideNiger is one of the hottest countries in the world by average temperature: a landlocked state of flat, sandy Sahelian plain that stretches through the southern savanna, the Sahel proper, and up into the Sahara covering more than half its area. There is no coastline and no mountain range strong enough to force rain out of the air, so the climate is a desert one with very little rain, extreme heat, and a huge difference between day and night. Seasonal rainfall, when it comes, arrives with the summer storms that push north from the Gulf of Guinea.
Main climate types
Almost the whole country falls into the desert and steppe groups of the Köppen classification: hot desert in the north and centre, hot semi-arid steppe in the south. The far southern fringe, around Niamey and toward Benin, gets enough summer rain to be classed as savanna. The only feature that breaks the flatness is the highland massif of the Aïr Mountains, which sits in the desert and catches a little extra cloud.
Temperatures
Niamey averages about 25 °C in January and about 31 °C to 32 °C in July, but daily highs in the south commonly pass 40 °C, especially in May and June, just before the rains. In the Sahara north, summer highs can be even higher while the winter is mild. The contrast inland is the diurnal range: clear desert nights in December and January often fall below 10 °C, and frost has been recorded in the far north.
Rainfall
Annual rainfall is tiny and falls away hard from south to north. Niamey receives about 600 mm to 700 mm, most of it between July and September, while the Sahelian belt gets under 400 mm and the northern deserts under 100 mm, with years recording almost nothing. The dry season runs from October to May, and during that time the harmattan, the dust-laden wind from the Sahara, hazes the air and often settles on the cities.
When to go
The cool season, from November to February, when highs are still warm but nights are crisp, is the most comfortable time in the south. The summer months of June to September bring the rain, and dust haze is a feature of the dry season.
