The Nigerian Meteorological Agency (NiMet) has issued another heat stress advisory, warning residents across 19 states, the Southeast, and coastal areas. This marks the second alert in just a few weeks.
According to the bulletin released on Tuesday, the regions most at risk include north-central and eastern states such as Kebbi, Niger, Kwara, Oyo, Kogi, Nasarawa, Benue, Enugu, Anambra, Abia, Ebonyi, Cross River, and the Federal Capital Territory (FCT). Other vulnerable areas mentioned in the report include parts of the South-West, coastal states, as well as Taraba, Adamawa, Plateau, Kaduna, Zamfara, and Sokoto.
NiMet cautioned that temperatures could soar to 42°C, with elevated humidity levels worsening discomfort in the affected regions over the next few days.
A similar advisory was issued earlier in February 2025, urging Nigerians to stay hydrated, carry portable fans, and reduce physical exertion between noon and 3:00 pm to avoid excessive heat exposure.
Mathias Bwala, a former official at the National Environmental Standards and Regulation Enforcement Agency (NESREA), has attributed the frequent occurrence of heat stress to the ongoing effects of climate change.
Another environmental analyst linked the increasing heat stress to long-term environmental degradation, including desert expansion, air contamination, and water pollution. The shrinking tree cover due to desertification is a key concern, as trees play a crucial role in moderating temperatures and balancing ecosystems.
The University of Iowa highlights several conditions that contribute to heat stress, including excessive air temperatures, exposure to radiant heat sources, high humidity, direct contact with heated surfaces, and strenuous physical work.
To minimize health risks, NiMet advises the public to take necessary precautions such as drinking plenty of water, avoiding prolonged exposure to sunlight, and opting for lightweight, breathable clothing.
The agency also urges people to limit outdoor activities during peak heat hours and to pay special attention to those who are more vulnerable, including children and the elderly.
With temperatures projected to range between 36°C and 42°C in northern areas and 34°C to 39°C in southern regions, NiMet stresses the importance of following safety guidelines to reduce the risk of heat-related illnesses.
