Technical Note on the 2026 Rainy Season in West Africa and the Sahel
For 2026, El Niño should be considered an important risk factor, but not the sole determinant of the rainy season. Conditions observed in the tropical Atlantic, the Mediterranean, and the Indian Ocean may significantly modulate its influence. The season is expected to be characterized by pronounced regional contrasts, with the likely coexistence of areas exposed to rainfall deficits and areas at risk of flooding. Continuous vigilance and regular forecast updates will be essential throughout the season.
