The Ghana Meteorological Agency (GMet) has warned that a strong El Niño event is likely to affect Ghana's weather through the first half of 2027. This natural climate pattern occurs when the central and eastern parts of the Pacific Ocean become warmer than usual, affecting weather patterns worldwide, including rainfall and temperatures in West Africa.
GMet's technical advisory published on October 30 stated that observations from its monitoring systems and international climate institutions point to a potentially strong El Niño event. The event is expected to peak between November 2026 and January 2027 before gradually weakening in the first half of next year.
Although much of Ghana is expected to experience drier conditions, GMet has cautioned that some parts of the south could record above-normal rainfall, with the possibility of flooding. These areas include inland parts of the Greater Accra and Central regions, south-western parts of the Volta and Eastern regions, parts of the Bono and Savannah regions, as well as north-western areas of the Upper West Region.
GMet's projections show that most parts of Ghana are likely to experience below-normal rainfall, while temperatures are expected to remain above average in many parts of the country. However, relatively cooler conditions are expected in the south-west and parts of the Volta Region, particularly between Ho and Kete Krachi.
The dry season is expected to begin in late November 2026 and continue until March 2027, with many areas likely to experience particularly hot, dry, and dusty conditions. These conditions could increase the risk of bushfires and water shortages while putting additional pressure on crops and livestock.
GMet has advised farmers to follow its weather forecasts and guidance from the Ministry of Food and Agriculture before planting or replanting their crops. Residents in northern Ghana have been urged to reduce their exposure to dust and seek medical attention immediately if they experience symptoms such as fever, severe headache, or a stiff neck.
Despite the forecast of below-normal rainfall across much of the country, GMet has cautioned that sudden heavy downpours and localised flooding remain possible. Communities along the Volta River, as well as residents in flood-prone and low-lying urban areas, have therefore been urged to remain alert and follow safety instructions from the National Disaster Management Organisation (NADMO) and the Volta River Authority (VRA).
Key points
- A strong El Niño event is likely to affect Ghana's weather through the first half of 2027.
- The event may cause difficulties for farmers and possible water shortages.
- GMet will continue to provide updated weather forecasts as conditions change.
