South Sudan: Floods Snapshot (As of 10 October 2025)

Heavy rainfall and rising water levels along the River Nile continue to inundate large parts of South Sudan. As of 9 October, flooding has affected an estimated 886,106 people across 26 counties in six states, with Jonglei and Unity accounting for over 91 per cent of the affected population. Nearly 287,300 people have been displaced across 16 counties, with many now sheltering on higher ground. Widespread damage has been reported to homes, crops, schools, boreholes, and other public infrastructure. With rains ongoing and assessments still underway, the number of affected people is expected to rise. In Jonglei State, severe flooding was reported on 8 October in Khorwac Town, Canal/Pigi County, following overflow from the River Nile. All public facilities—health centres, schools, and water points—have been submerged. People have relocated to higher ground. In Upper Nile State, flooding in Malakal County on 6 October displaced hundreds from six villages, forcing them to seek refuge on elevated ground. In Unity State, extensive flooding in Rotriak (Rubkona County) has displaced families to roadside areas, where risks of injury and snakebites are increasing. Since 29 September, persistent rains have severely damaged roads in Rubkona and Bentiu Towns, cutting off access. Most southern parts of the county are now accessible only by canoe, which humanitarian actors are using to deliver aid. The dykes near the Bentiu UNMISS base are reported to be in poor condition and at risk of breaching. A failure could flood Bentiu IDP camp, home to nearly 109,000 displaced people. IOM began urgent repairs on 7 October. Despite access challenges caused by impassable roads, especially in Unity, Upper Nile, and Jonglei States, humanitarian partners are delivering life-saving assistance to affected communities.
