Although generally equatorial, the climate is not uniform as the altitude modifies the climate. Southern Uganda is wetter with rain generally spread throughout the year. At Entebbe on the northern shore of Lake Victoria, most rain falls from March to June and the November/December period.
Further to the north a dry season gradually emerges; at Gulu about 120 km from the South Sudanese border, November to February is much drier than the rest of the year. The northeastern region has the driest climate and is prone to droughts in some years. Rwenzori in the southwest on the border with DR Congo receives heavy rain all year round. The south of the country is heavily influenced by one of the world’s biggest lakes, Lake Victoria, which contains many islands.
It prevents temperatures from varying significantly and increases cloudiness and rainfall.
