Harmattan: GMet warns of drier, dustier conditions and possible flood from late November

The Ghana Meteorological Agency (GMet) has issued a warning that a robust El Niño event brewing in the Pacific Ocean is set to impact Ghana's climate from late November 2026 to March 2027. This phenomenon could bring hotter temperatures, extended periods of dryness, and increased dust levels. While the agency anticipates below-normal rainfall across most of the country, certain regions, including parts of Greater Accra and Central regions, southwestern Volta and Eastern regions, Bono and Savannah regions, and north-western Upper West Region, may experience above-normal rainfall.

Temperatures are expected to be warmer than average nationwide, but some areas, such as the south-west and the Ho to Kete Krachi stretch of the Volta Region, may see cooler-than-average conditions, particularly between February and April 2027, which could heighten the risk of meningitis, especially in northern Ghana. The extended dry spell and dustier conditions may exacerbate the risk of bushfires, water shortages, and strain on crops and livestock.

GMet advises farmers to stay informed through weather updates and agricultural advisories and to consider early-maturing, drought-tolerant crop varieties. Residents in northern Ghana should minimize dust exposure and seek medical attention if they develop symptoms indicative of meningitis. The general public is encouraged to maintain adequate hydration and avoid strenuous outdoor activities during peak heat hours.

Despite the forecast of below-normal rainfall, communities along the Volta River and flood-prone urban areas should remain vigilant about potential short, intense downpours and localised flooding. GMet, in collaboration with various sectors, will continue monitoring the situation and updating weather outlooks as necessary.
