19 September 2025: Seasonal precipitation predictions

Overview:

Above-normal rainfall is expected in late September across the northern Sahel, Sudan, the southern Arabian Peninsula, and along the Indo-Pakistan border, and may persist into early October in West Africa and the Indo-Pakistan border area. A drying trend is anticipated across most regions in October and November due to a negative Indian Ocean Dipole. In December, rainfall may return to localized areas in all three regions, particularly along the Red Sea coasts of Egypt, Sudan, and Saudi Arabia, and could persist through February. Above-normal rainfall is also forecast for spring breeding areas in the Central and Eastern Regions. These rainfall patterns will support locust breeding in the northern Sahel and Sudan through September and early October. Breeding should decrease in November but may intensify again from December to March, especially along the Red Sea coasts.
