NiMet Issues Heat Stress Warning as Climate Change Impacts Intensify

NiMet has issued a heat stress warning for 19 Nigerian states, citing rising temperatures and predicted extreme heat between 36°C to 42°C. The warnings relate to climate change impacts, with recommendations for safety, including hydration and limiting sun exposure. Experts link increased heat to desert encroachment and pollution, underscoring the need for vigilance to prevent health issues.

The Nigerian Meteorological Agency (NiMet) has issued a heat stress warning affecting 19 states, particularly in the Southeast and coastal regions, marking the second warning within a month. The North-Central and Eastern regions, encompassing Kebbi, Niger, Kwara, Oyo, Kogi, Nasarawa, Benue, Enugu, Anambra, Abia, Ebonyi, Cross River, and the Federal Capital Territory (FCT), are highlighted as particularly vulnerable. Regions in the South-West, coastal areas, Taraba, Adamawa, Plateau, Kaduna, Zamfara, and Sokoto are also at risk.

NiMet’s alert emphasizes rising temperatures, which may reach up to 42°C, alongside high humidity levels over the forthcoming three to four days, potentially leading to severe thermal discomfort. Earlier warnings were also issued in February 2025, advising the public to stay hydrated, use portable fans, and refrain from strenuous activities from noon to 3:00 PM.

Former NESREA field officer, Mathias Bwala, links this recurring heat stress to climate change impacts. Additionally, another expert identifies factors such as desert encroachment, air pollution, and water pollution as contributors. Desertification decreases tree numbers, thus elevating direct sunlight exposure due to trees’ critical role in temperature regulation.

The University of Iowa identifies several contributing factors to heat stress: high air temperatures, radiant heat sources, elevated humidity, contact with hot objects, and vigorous physical activity. To combat the effects of extreme heat, NiMet advises the public to take precautions, including staying hydrated, avoiding sun exposure, and wearing lightweight clothing.

It is also recommended to limit outdoor activities during the hottest times of the day and to provide extra care for vulnerable populations like the elderly and children. As temperatures climb, NiMet underscores the necessity of vigilance and compliance with these guidelines to avert heat-related health issues, with anticipated temperatures between 36°C to 42°C in the North and 34°C to 39°C in the South.

The recurrent heat stress warnings issued by NiMet highlight the urgent need for public awareness regarding the impacts of climate change. With rising temperatures and humidity levels predicted, it is vital for individuals, especially vulnerable groups, to adhere to precautionary measures to mitigate health risks. The interconnection of environmental factors such as desertification and pollution emphasizes the necessity for a coordinated approach to climate action and individual responsibility in combating these growing challenges.
