Haiti Seasonal Monitor, May 2026

Haiti - Seasonal Monitor June 2, 2026 Despite declining rainfall, near-average vegetation conditions persist across Haiti Key Messages Figure 1 Rainfall declined consistently during the last 30 days. Above-average temperatures increased evapotranspiration rates nationwide. SSEBop Cumulative ET anomaly percent of median (2013–2022) March 1 – May 20, 2026. Below-average rainfall is expected during the next 10 days. Irrigation systems and residual soil moisture continue to support crop development despite declining rainfall. Irrigation systems support crops activities During May, rainfall declined across most of the country while temperatures rose above average. These conditions increased evapotranspiration rates throughout the country. As shown in Figure 1, areas including Gonaïves, Hinche, Fort-Liberté, and Portau-Prince recorded evapotranspiration rates more than 50 percent above the median (dark green), while most other areas registered anomalies of 20 to 30 percent above normal. Despite these conditions, irrigation systems and residual moisture from March and April rainfall continue to support average to above-average vegetation conditions. However, rainfall deficits are likely to worsen in the coming weeks. Forecasts indicate below-average rainfall through early June. Figure 2 shows that cumulative rainfall from May 26 to June 10 could reach only 45 to 60 percent of normal levels across large parts of the country. Combined with forecast above-average temperatures, these conditions will likely reduce soil moisture and place increasing stress on rainfed crops.

Field observers continue to report average levels of pests and crop diseases despite rising temperatures and high prices for agricultural inputs, including pesticides and fertilizers.
