When is Niger’s rainy season?

In the southern region of Niger, the climate is characterized by a single, short rainy season that typically lasts between one and four months, depending on the latitude.1

The season begins when southern trade winds from the Atlantic meet the dry harmattan winds, an encounter that triggers violent line squalls between April and May. While the duration and timing of the rains can vary significantly from year to year, August is consistently the rainy month across the country, with the exception of the far north, where rainfall remains unpredictable.1
