Haiti Seasonal Monitor: Dry conditions persist in southern Haiti, 15 October 2026

FEWS NET's Haiti seasonal monitor of 15 October 2026, reporting on vegetation health and rainfall.

The key messages are three. Southern Haiti continues to experience dry conditions. Vegetation conditions continue to deteriorate around Jacmel and Les Cayes, as well as in parts of Ouest and Grand'Anse departments. And below-average rainfall is expected to persist in southern Haiti, negatively affecting normal crop development.

On vegetation, consistently below-average rainfall over the last 45 days has affected vegetation health across southern Haiti, shown as NDVI as a percent of the 2003-2022 mean for 11 to 20 September 2026. Erratic rainfall distribution and cumulative moisture deficits have reduced water availability for irrigation, and high temperatures are accelerating soil moisture depletion, which is expected to reduce end-of-season crop yields.

On rainfall, estimates since 26 August and forecasts through 10 October indicate totals 25 to 50 percent above average across northern Haiti and average rainfall in the central region, while southern Haiti, particularly Sud-Est, continues to experience below-average rainfall. Increased evapotranspiration and declining groundwater levels are likely to reduce water availability for irrigation further. Higher temperatures are also shortening pest reproduction cycles, which makes effective pest control essential to prevent crop damage.
