South Sudan Weather Forecast

South Sudan has a tropical climate with a pronounced wet season from April to November driven by the northward shift of the Intertropical Convergence Zone. Annual rainfall ranges from 700mm in the drier north to over 1,500mm in the equatorial south near the borders with Uganda and the Democratic Republic of the Congo. Temperatures remain high year-round, with Juba averaging around 37°C during the hottest months of February and March.

The Sudd, one of the world's largest wetlands, dominates the central landscape and expands dramatically during the rainy season as the White Nile overflows its banks. This vast marshland influences local weather patterns by increasing humidity and moderating temperatures in the surrounding areas. Severe flooding is an annual concern, with entire communities displaced when river levels peak between August and October.

The dry season from December to March brings lower humidity and cooler nighttime temperatures, but daytime heat remains intense. Localized thunderstorms can develop rapidly during the transition months, producing heavy downpours, lightning, and strong winds.
