<P> Great parts of North Africa and Southern Africa as well as the whole Horn of Africa mainly have a hot desert climate , or a hot semi-arid climate for the wetter locations . The Sahara Desert in North Africa is the largest hot desert in the world and is one of the hottest , driest and sunniest places on Earth . Located just south of the Sahara is a narrow steppe ( a semi-arid region ) called the Sahel , while Africa 's most southern areas contain both savanna plains , and its central portion contains very dense jungle ( rainforest ) regions . The equatorial region near the Intertropical Convergence Zone is the wettest portion of the continent . Annually , the rain belt across the country moves northward into Sub-Saharan Africa by August , then passes back southward into south - central Africa by March . Areas with a savannah climate in Sub-Saharan Africa , such as Ghana , Burkina Faso , Darfur , Eritrea , Ethiopia , and Botswana have a distinct rainy season . El Nino results in drier - than - normal conditions in Southern Africa from December to February , and wetter - than - normal conditions in equatorial East Africa over the same period . </P>
