Climate & when to go
Sudan’s climate ranges from hot and dry in the north to humid and tropical in the equatorial south. September to April is the best time to visit. Northern temperatures can exceed 40°C year-round, but peak from April to July. The heaviest rains (rarely more than 150mm in Khartoum) in July and August (Port Sudan’s meagre rainy season is October to December) present few problems for travel in the north, though wreak havoc on roads in the Nuba Mountains. Fierce dust storms (the haboob) blow occasionally from July to August and November to January. In the slightly cooler south it rains year-round, but April to November is the wettest time.
