Nigeria: Heatwave forecast nationwide through at least April 5

High temperatures are forecast to persist across much of Nigeria through at least April 5. Officials have warned of high temperatures across much of the country; an extreme danger level (highest level on a four-tier scale) heat index is in place across northern Nigeria. Danger level heat index is in place across most of the rest of the country. Officials have advised the public to take precautions to minimize the impact of the high temperatures.

The extended period of very high temperatures and dry conditions may magnify the potential for wildfires throughout the region. Heatwaves pose a health threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration.

Overheated vehicles could prompt traffic disruptions in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on vehicles and make tire blowouts more common. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
