Annual rainfall varies from about 40 inches (1,000 mm) in the south to less than 10 inches (250 mm) in the north. To the south, in the Sudanic zone, the climate becomes increasingly of the tropical wet-dry type, with a greater variability of temperature and rainfall and greater total rainfall than the north.įour seasons may be distinguished in Burkina Faso: a dry and cool season from mid-November to mid-February, with temperatures dropping to about 60 ☏ (16 ☌) at night a hot season from mid-February to June, when maximum temperatures rise into the low 100s F (about 40 ☌) in the shade and the harmattan-a hot, dry, dust-laden wind blowing off the Sahara desert-is prevalent a rainy season, which lasts from June to September and an intermediate season, which lasts from September until mid-November.

The lateritic (red, leached, iron-bearing) layer of rock that covers the underlying crystalline rocks is deeply incised by the country’s three principal rivers-the Black Volta (Mouhoun), the Red Volta (Nazinon), and the White Volta (Nakambé)-all of which converge in Ghana to the south to form the Volta River.
