A very strong El Niño is expected for late 2026, with a strength comparable to the severe 2023 and 1997 seasons. The Indian Ocean Dipole has been at the edge of its positive threshold and is likely to stay positive through the season. This could lead to heavy Deyr rains.

The GHACOF74 outlook confirms a wetter-than-normal Deyr season, with a high likelihood of exceeding 400 mm of rainfall over parts of central-southern Somalia. However, the severity of the season is still uncertain. Further details on the expected flood exposure and preparedness are available, including an analysis that benchmarks past El Niño seasons to provide a severity scale.
