Ghana Faces Hotter, Drier Months as GMet Warns of El Niño Risks to Food, Water and Power
GMet warns Ghana could face hotter, drier and dustier conditions into 2027. Here's what its official forecast says about crops, health, flooding and hydropower.
Ghana’s Meteorological Agency has urged coordinated preparations for a developing El Niño event that could bring hotter, drier and dustier conditions into 2027. Farmers, health services, water managers and electricity planners face different risks — and the agency warns that heavy rain and localised flooding remain possible.
ACCRA | 2 November 2026 — Ghana’s Meteorological Agency (GMet) is calling for urgent national preparedness as a strong El Niño develops in the tropical Pacific, potentially increasing heat stress, dry-season water pressure and agricultural disruption over the coming months.
In a technical assessment published at the end of October and highlighted by the Ghana News Agency on Monday, GMet identified November 2026 to April 2027 as a period of heightened concern. It said heat stress could be particularly severe between February and April 2027, especially in northern Ghana.
El Niño is a recurring warming of the central and eastern tropical Pacific that can influence weather patterns around the world. It is not a guarantee that every part of Ghana will experience drought or that rainfall will be uniformly below normal.
What GMet is forecasting for Ghana
The agency’s November rainfall outlook projects generally normal-to-below-normal rainfall over much of the country, with parts of the Forest and Transition zones more likely to receive normal-to-above-normal rainfall. Its wider 2026–27 assessment points to warmer-than-average temperatures in many locations and the potential for more dust and prolonged dry spells during the dry season.
Crucially, GMet also cautions that short, intense downpours and localised flooding remain possible, particularly in vulnerable southern and Volta Basin communities. Drier seasonal conditions do not eliminate flood risk.

November 2026
Normal-to-below-normal rainfall is expected in much of Ghana, with regional exceptions.

Farmers and food security
Dry spells may affect planting, soil moisture, pasture and livestock water supplies.
Recommended actionConsult local extension officers and GMet’s ten-day agrometeorological advisories before changing planting dates.

Frequently asked questions
Does El Niño mean Ghana will have no rain?
No. GMet expects regional variation, and heavy local rainfall can still occur.
Will Harmattan be more severe everywhere?
No uniform nationwide severity is established. Monitor updated local forecasts.
Will food prices definitely increase?
No reliable national food-price increase can be calculated from the climate outlook alone.
Are electricity cuts scheduled?
No nationwide power-cut timetable is established by GMet’s technical assessment. Energy agencies have been urged to plan ahead.
Can flooding occur during a drier season?
Yes. Isolated intense rainfall can cause flash flooding even when seasonal totals are below normal.
Preparedness matters more than a single probability
The practical impact of a climate event depends on local rainfall, water reserves, infrastructure, agricultural decisions and public-health preparedness.
National forecasts should trigger planning, not unsupported predictions of inevitable crop losses, food-price increases or electricity shortages.
