The Benguela Current is a cold sea current originating from Antarctica and only finding its way north along the southwest coast of Africa. The formation of the Namibian deserts is the cause thereof. The cold barrier along the coast collides with the scorching heat of the mainland and the large solar radiation creates extensive cloud formation above the water. Only during cold nights, the clouds and sea fog can reach the deserts. The little moisture generated by the clouds and fog is still sufficient to enable a wide variety of life in the desert. However, this is not sufficient for everything.
