• The North of the country belongs to the Sahel zone. This area typically sees less than 600mm of rainfall and the dry season can last between 8 and 10 months.

• The largest climatic zone is the Sudan-Sahel zone, which covers central Burkina Faso . Rainfall is superior to that in the North but rarely goes past 1000mm.

• Southern Burkina Faso is covered by the Sudan zone, which is by far the most humid of the regions. Its rainy season lasts 6 months with rainfall of up to 1300mm.
