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

Ghana is expected to experience a harsher-than-usual Harmattan season from late November, with the Ghana Meteorological Agency (GMet) warning of drier conditions, increased dust and prolonged dry spells across parts of the country.

According to GMet’s latest seasonal outlook, the dry season, expected to begin in late November 2026 and continue through March 2027, could bring more challenging weather conditions, with possible effects on health, agriculture, water supply and daily activities.

The agency’s outlook indicates that most parts of the country are likely to record below-normal rainfall through December, alongside warmer-than-average temperatures. However, some areas, particularly parts of the Central, Greater Accra, Volta, Eastern, Bono, Savannah and Upper West regions, could experience periods of above-normal rainfall.

GMet cautioned that the expected dry conditions do not rule out sudden heavy rainfall, which could trigger localised flooding, particularly in parts of southern Ghana.

The anticipated increase in dry and dusty conditions could also heighten the risk of bushfires, worsen water shortages and place additional pressure on crops and livestock. Communities in northern Ghana may face an increased risk of meningitis during the dry season.

Farmers have been advised to seek guidance from GMet and the Ministry of Food and Agriculture when planning their activities, consider early-maturing and drought-tolerant crop varieties, and avoid practices such as bush burning that could worsen fire risks.

Residents have also been urged to conserve water, stay hydrated and take precautions against dust exposure, particularly during periods of strong winds. People who spend extended periods outdoors should take steps to protect themselves from the dry conditions.

GMet further advised communities in flood-prone areas, including those along the Volta Basin, to remain alert and follow weather and safety advisories issued by the National Disaster Management Organisation and the Volta River Authority.

The agency said it would continue monitoring weather conditions and providing regular updates, including ten-day agricultural weather bulletins, to support planning and preparedness during the season.
