Sudan: When to go

Sudan's climate ranges from your typical blisteringly hot desert weather in the north to humid and tropical in the equatorial south. Any rain in the north (rarely more than 150mm/6in per year) normally falls between July and September. In the south, annual rainfall can exceed 1000mm (39in) and usually occurs between April and November. Even in January daytime temperatures above 30°C (86°F) are almost a certainty, and at night in the middle of the year the mercury still lingers around 25°C (77°F). Northern temperatures are particularly high, climbing to more than 40°C in Khartoum in summer when there are also frequent dust storms. Humidity is only really noticeable in the south and is rarely uncomfortable.
