What is heat index?

The heat index combines both temperature and humidity to determine a real feel of the temperature. For example, if the temperature is 80 degrees, and there is 80 percent humidity, the heat index is 84. In other words, it may only be 80°F outside, but because of the humidity, your body is losing heat at a slower rate, equivalent to a dry temperature of 84°F.
