Extreme heat Hazard level: Low ?

Extreme heat occurs when air temperatures significantly exceed normal seasonal averages for prolonged periods, creating conditions that stress human thermoregulation and can lead to heat-related illness. The hazard is measured using indices that combine temperature and humidity to assess heat stress on the human body, such as wet bulb globe temperature (WBGT). The severity depends on temperature intensity, duration, humidity levels, nighttime cooling, and the vulnerability of exposed populations.

In the area you have selected (Lesotho) extreme heat hazard is classified as low based on modeled heat information currently available to this tool. This means that there is approximately 1% chance per year that at least one period of prolonged exposure to extreme heat, resulting in heat stress, will occur (about 5% chance in the next five years). Risk studies, project planning decisions, project design, and construction methods should seek further information on whether the level of extreme heat hazard needs to be taken into account in the lifetime of the project.
