The park has a semi-arid climate with just one rainy season per year (April-September) and rainfall is light. The valley of the Narus river in the south of the park receives some 890mm of rain/year while just 635mm of rain/year falls in the Kidepo valley to the north. Both rivers are seasonal, and dwindle and disappear in the dry season. During these months, the only permanent water in the park is found in wetlands and remnant pools along the southern Narus valley near Apoka and as a result, wildlife is concentrated in this area. This consideration, combined with the valley’s open, savanna habitat, makes the park a prime game viewing location on a Uganda safari.
