Weather Patterns & Effects
South Sudan’s weather brings both advantages and disadvantages. The country often experiences:
- Widespread drought, caused by above or below normal rainfall across the country.
- Drought in certain regions, due to concentrated above or below normal rainfall.
- Floods, which happen when the Nile River and its tributaries overflow during the wet season (especially in August and September).
According to climatology reports, South Sudan is home to the world’s largest swamp. However, rising temperatures and unpredictable rainfall threaten the biodiversity of this natural treasure.
Rainfall patterns in South Sudan extend beyond its borders, reaching Sudan to the north, Ethiopia to the east, and Uganda to the south.
