Ghana is too hot, and this is why
Ghana is feeling unusually hot because the Ghana Meteorological Agency (GMet) has forecast above-normal temperatures nationwide, while much of the country is receiving below-normal rainfall.
The result is intense sunshine, high humidity, dry spells and less cooling rain, making the heat feel worse, especially in Accra.
What is El Niño?
El Niño is a natural climate pattern that occurs when sea-surface temperatures in the central and eastern Pacific Ocean become unusually warm. That warming disrupts global wind and rainfall patterns, bringing drought to some regions and floods to others.
For West Africa, El Niño often weakens or disrupts the monsoon, leading to hotter, drier conditions and unreliable rainfall.
Why Ghana feels hotter
Ghana is in the September–November minor rainy season, but GMet expected rainfall to be normal to below normal across most areas.
Less rain means clearer skies, stronger sunshine and less evaporative cooling. GMet has warned that these conditions could increase heat stress on people, crops and livestock, while raising demand for water and electricity.
Accra feels even hotter because of the urban heat island effect. Concrete buildings, asphalt roads, traffic, limited trees and dense development trap heat, making the city warmer than surrounding rural areas.
El Niño is amplifying it
El Niño is not the only reason Ghana is hot, but it is making conditions worse. GMet had warned that a strengthening El Niño would likely suppress rainfall over the Gulf of Guinea from August onwards, increasing the risk of dry spells and early-ending rains.
Climate change is the bigger long-term driver. Ghana’s average annual temperature has already risen by about 1°C over the past 30 years, making heatwaves more frequent and intense.
Why Ghanaians should care
El Niño can affect food, water, electricity and health.
Less rain can reduce crop yields and push up food prices. Lower water levels can affect hydropower generation, while heat and changing rainfall can worsen malaria, cholera and other water-related diseases.
Farmers, traders, fisherfolk and outdoor workers face the greatest risk because their incomes depend directly on weather conditions.
Why Africa should worry
Africa is especially vulnerable because many countries depend on rain-fed agriculture, while millions already face food insecurity and weak water systems.
El Niño can trigger a chain reaction: poor harvests lead to food inflation, food inflation deepens hunger, and droughts or floods displace communities and spread disease.
Countries most affected
The countries facing the greatest El Niño risks include Zimbabwe, Mozambique, Malawi, Zambia, Angola, Madagascar, Lesotho, South Africa, Botswana and Namibia in Southern Africa, where drought and failed rains are the main threat.
In East Africa and the Horn, Ethiopia, Somalia, Kenya, Uganda, South Sudan, Sudan, Eritrea and Djibouti face a mix of drought and flood risks.
In the Sahel, Mali, Burkina Faso, Niger, Chad, northern Nigeria and Mauritania face localised drought and heat risks.
Ghana, Côte d’Ivoire, Togo, Benin and Nigeria fall within the Gulf of Guinea belt, where El Niño can disrupt the minor rainy season and raise temperatures.
What next for Ghana
Ghana may not face the worst drought conditions in Africa, but it must prepare for unreliable rain: dry spells during planting, heat during harvest and heavier bursts of rain when they eventually come.
The immediate response should focus on water conservation, protecting farmers, checking on vulnerable groups and planting more trees in cities. The long-term response must tackle climate change and unplanned urban growth.
Ghana is hot now because of El Niño, climate change and urban heat working together. The danger is not just today’s temperature, it is what repeated heat and unreliable rain could mean for food, water and livelihoods.
