Extreme Heat

Extreme heat refers to weather conditions in which air temperatures are significantly higher than average for a given location and time of year, reaching levels that can pose serious risks to human health, infrastructure and ecosystems. It may occur during heatwaves or as isolated periods of unusually high temperatures and is often intensified by factors such as high humidity, urban heat island effects and persistent atmospheric patterns. Extreme heat increases the likelihood of heat-related illness and mortality, strains energy and water systems, and can exacerbate drought and wildfire risk.
