Description Complète
Moniteur saisonnier de FEWS NET pour Haïti, janvier 2026, daté du January 29, 2026. Des cumuls de pluie supérieurs à la moyenne, à distribution irrégulière, ont été signalés sur Haïti fin décembre et en janvier, augmentant les risques localisés de ruissellement et d'érosion. Les conditions de végétation étaient globalement supérieures à la moyenne grâce à des gains d'humidité du sol à court terme, avec un stress localisé persistant. Les conditions de début de printemps étaient globalement favorables, et le rapport note que ces bénéfices restaient fragiles en raison de l'irrégularité des pluies et de contraintes non climatiques. Le moniteur suit la saison en cours : cumuls pluviométriques rapportés à la moyenne de long terme, état de la végétation à partir du NDVI satellitaire, et ce que les deux impliquent pour les semis, le développement des cultures et la récolte. La date de couverture clôt la fenêtre de 30 jours couverte.

HAITÍ Seasonal Monitor
January 29, 2026
Above-average rainfall with Erratic Distribution over Haiti
Key messages
●
Above-average cumulative rainfall with erratic
distribution is reported over Haiti in late December–
January, increasing localized runoff and erosion risks.
●
Vegetation conditions are generally above average,
driven by short-term soil moisture gains, with localized
stress persisting.
●
Current and forecast early spring conditions are broadly
favorable, but benefits remain fragile due to rainfall
irregularity and non-climatic constraints.

Rainfall Variability, Vegetation Response, and
Agroclimatic Implications

During late December 2025 and January 2026, Haiti
experienced above-average cumulative rainfall. However,
these positive anomalies were primarily driven by episodic
heavy rainfall events interspersed with prolonged dry spells,
reflecting significant intra-seasonal variability. This uneven
temporal distribution reduced effective infiltration and
increased localized risks of surface runoff, soil erosion, and
nutrient leaching, particularly in lowland areas and steeply
sloped watersheds. The rainfall map (Figure 1) highlights the
spatial heterogeneity of these precipitation patterns across
the country.

Index, January 11 -20, 2026.
Vegetation conditions, as indicated by positive NDVI
anomalies, are generally above average across large portions
of Haiti. This response reflects short-term soil moisture
recharge following late-December rainfall, combined with
near- to slightly below-average temperatures that reduced
evapotranspiration demand. The most pronounced
vegetation improvements are observed in parts of Artibonite,
Ouest, Sud-Est, and the Gonaïves area, although localized
pockets of vegetation stress persist in areas affected by

rainfall intermittency. These contrasts are illustrated in the NDVI anomaly map (Figure 2).
From an agroclimatic perspective, current conditions are broadly conducive to the preparation and early initiation of the
Spring agricultural season. However, the sustainability of these conditions remains highly dependent on improved rainfall
regularity in the coming weeks. February forecasts indicate near-average rainfall and temperature conditions, which could
support crop establishment if precipitation becomes more evenly distributed. Nevertheless, anticipated impacts on food
security are expected to remain limited and uneven, as the translation of favorable climatic conditions into durable food
security gains continues to be constrained by non-climatic factors, including access to agricultural inputs, security conditions,
and market functioning.
