FEWS NET reported that the 2026–27 El Niño had strengthened rapidly and that below-average rainfall had already been observed in parts of the West African Sahel, including northeastern Nigeria. It warned that rainfall disruptions could worsen food insecurity during the lean season following a poor growing season, while Southern Africa also faces a risk of below-average rainfall.
Insufficient rain could reduce regional crop production and tighten food supplies, potentially lifting prices if poor growing conditions persist. The report describes a risk outlook rather than confirmed crop losses, so the price impact remains uncertain.
