heat wave index

The heat wave index is a measure used to assess how extreme and prolonged a period of excessively hot weather is. It combines factors like high temperatures, humidity levels, and the duration of the hot weather to determine the overall severity. Essentially, it helps to quantify when weather conditions are dangerously or unusually hot, indicating potential health risks and the need for precautions. The higher the index value, the more intense and dangerous the heat wave is considered. This tool aids authorities and individuals in understanding and responding to extreme heat events effectively.
