The worst-affected regions are Maradi and Zinder in the centre of the country, Dosso in the southwest, and Tahoua in the west.
The rainy season, which starts in June and can last until October, regularly claims lives, but the toll has been particularly heavy this year.
In 2021, 70 people were killed and 200,000 people were affected. The death toll in 2020 was 73.
In neighbouring Nigeria, more than 600 people have died since June in the deadliest floods in a decade.
“According to all our studies, we can link these rains to climate change,” head of the national meteorological agency Katiellou Gaptia Lawan told AFP.
The “rainfall is intense”, while runoff water can no longer make its way into the soil because it has been “degraded by human activity”, he explained.
