This Bulletin provides an overview and implications of June, July, August, and September (JJAS) 2025 seasonal forecast for South Sudan government, partners, communities and decision makers to take appropriate measures in saving lives and protect livelihoods. The analysis is based on pre-diction developed by IGAD Climate Prediction and Application Center (ICPAC) in collaboration with National Meteorological and Hydrological Services (NMHSs) of member countries. Subse-quently, the seasonal forecast was downscaled to South Sudan forecast by the South Sudan Me-teorological Service.

Rainfall forecast: June - September period is a major rainfall season over most parts of South Su-dan constituting 70% in both bimodal and unimodal rainfall zones with high probability (>90%) of rainfall exceeding 400 mm.

Above-Normal rainfall with 55 - 60% probability is expected across Eastern Equatoria, Greater Pibor Administrative Area, parts of Jonglei and Upper Nile States, while 40 - 45% probability of moderate levels of precipitation (Normal rainfall) anticipated across Central Equatoria, Western Equatoria, Unity, some parts of Western Bahr el Ghazal, Jonglei and Upper Nile States.

Additionally, the current water level in Lake Victoria is nearly the same as it was in 2024 and higher than in 2023, posing a risk that requires ongoing monitoring.
