The Sahel has a hot semi-arid climate (Köppen climate classification BSh). The climate is typically hot, sunny, dry and somewhat windy all year long. The Sahel's climate is similar to, but less extreme than, the climate of the Sahara desert located just to the north. The Sahel mainly receives a low to very low amount of precipitation annually.
The Sahelian kingdoms were a series of centralized kingdoms or empires that were centered on the Sahel, the area of grasslands south of the Sahara, from the 8th century to the 19th. The wealth of the states came from controlling the trade routes across the desert.

The southern fringe of the desert along the border with the Sahel receives summer cloudiness and rainfall due to the arrival of the Intertropical Convergence Zone from the south and the annual average rainfall ranges from 100 millimetres (4 in) to 250 millimetres (10 in).

A major drought started in the Sahel region in the late 1960s and caused severe damage in 1972 and 1984. It was thought to be related to vegetation loss, global warming, and sea surface temperature anomalies. [28] During this period, Lake Chad shrunk considerably and fluctuated in the range of 2,000 to 5,000 km 2 (770 to 1,930 sq mi) thereafter ...

This band is a transitional region between the Sahara's very arid center (the Sahara desert ecoregion ) to the north, and the wetter Sahelian Acacia savanna ecoregion to the south. [ 1 ]
