(2026-06) Moniteur saisonnier : la baisse des pluies et les températures élevées accroissent le stress hydrique, 1er juillet 2026
Resume — Les déficits pluviométriques ont persisté sur une grande partie d'Haïti pour un deuxième mois consécutif jusqu'à fin juin 2026, dépassant 55 pour cent de la moyenne habituelle de juin et localement plus de 70 pour cent dans le Sud-Est et l'Ouest. Les pluies favorables du début de la saison de printemps, l'humidité résiduelle du sol et l'irrigation soutenaient encore des conditions de végétation globalement proches de la moyenne, bien que celles-ci se dégradent progressivement. FEWS NET avertit que si des pluies inférieures à la moyenne et des températures supérieures à la moyenne persistent en juillet, le développement des cultures, les secondes semis et la production agricole localisée pourraient être affectés.
Constats Cles
- Les déficits pluviométriques ont persisté un deuxième mois consécutif sur une grande partie d'Haïti jusqu'à fin juin 2026.
- Les déficits ont dépassé 55 pour cent de la moyenne de juin, et localement plus de 70 pour cent dans le Sud-Est et l'Ouest.
- Les conditions de végétation restaient proches de la moyenne mais se dégradaient progressivement.
- L'humidité résiduelle du sol et l'irrigation soutenaient encore les cultures.
- La poursuite de pluies déficitaires et de températures élevées en juillet affecterait le développement des cultures et les secondes semis.

Reduced rainfall and high temperatures are increasing moisture stress
Key Messages
Figure 1
Rainfall deficits have persisted across much of Haiti for a
second consecutive month, with the largest deficits observed
in the Southeast and West.
Percent of mean (2003-2022) NDVI, June
11 - 20, 2026.
Favorable rainfall earlier in the spring season, residual soil
moisture, and irrigation continue to support generally nearaverage vegetation conditions, although vegetation conditions
are gradually deteriorating.
If below-average rainfall and above-average temperatures
persist through July, crop development, second planting
activities, and localized agricultural production could be
adversely affected.
Reduced rainfall and high temperatures are increasing
moisture stress
For the second consecutive month, rainfall has remained well below
average across much of Haiti, with deficits exceeding 55 percent of

the usual June average. The largest rainfall deficits are concentrated
in the Southeast and West, where cumulative deficits locally exceed
70 percent. Despite these deficits, vegetation conditions remain
generally near average across much of the country due to favorable rainfall received earlier in the spring season,
residual soil moisture, and continued use of irrigation systems. However, recent satellite imagery indicates localized
deterioration in vegetation health (Figure 1), suggesting that excess water availability from earlier in the season is no
longer sufficient to sustain normal crop development.
Above-average temperatures are accelerating evapotranspiration and further depleting soil moisture, increasing water
stress for crops. Although the spring season is still progressing relatively favorably in most areas, continued dry
conditions could result in localized production losses, particularly in areas with limited irrigation capacity.
Rainfall observations from the last 10 days and forecasts for the next 15 days (Figure 2) indicate that below-average
rainfall is likely to continue across much of the country. If these forecasts materialize, persistent moisture deficits may
delay second planting activities, reduce irrigation system effectiveness, and increase crop water stress. Combined with
above-average temperatures, these conditions could also favor the development of certain crop pests and diseases.
While current vegetation conditions remain generally favorable, continued rainfall deficits through the remainder
of the rainy season could accelerate vegetation deterioration and increase localized crop losses, particularly in the
Southeast and West.

Seasonal Monitor
FEWS NET’s Seasonal Monitor reports are produced for Central America and the Caribbean, West Africa, East Africa, Central Asia, and Somalia every 10-to-30 days during the region’s
respective rainy season(s). Seasonal Monitors report updates on weather events (e.g., rainfall patterns) and associated impacts on ground conditions (e.g., cropping conditions,
pasture and water availability), as well as the short-term rainfall forecast. Find more remote sensing information here.
