In early September 2026, Haiti experienced high temperatures and thunderstorm risks. The Unité hydrométéorologique d’Haïti (UHM) initially forecast temperatures between 33°C and 37°C, with localized heavy rainfall and thunderstorms expected in the Grand’Anse, Nippes, and Sud-Est departments, as well as potential evening showers in the West, Center, Artibonite, and North-East departments.

By September 6, conditions shifted toward mostly sunny weather, though a tropical wave southeast of the Dominican Republic was expected to trigger isolated, potentially stormy showers in the late afternoon or evening. These showers were anticipated to affect the South-East, Grand'Anse, Centre, Artibonite, West, and Nippes departments, with temperatures in Port-au-Prince reaching a maximum of 38°C.
