The Nile basin has two types of climates. In the northern part, the part where the Sudan and Egypt lie, has virtually no rainfall in the summer. In contrast the southern portion, which encompasses the Ethiopian Plateau, has heavy rains during the summer months. During the season between October and May both regions are relatively dry due to the presence of the northeast trade winds. There are parts of the East African lakes region and southwestern Ethiopia that have more tropical climates. Rainfall occurs throughout these regions. However, the rainy season is considered to occur from April to October.
