What is Heat Index? Heat index is often referred to as humiture, and is similar to wind chill in its attempt to measure perceived, rather than actual temperature. For example, an air temperature of 83°F with a relative humidity of 70% would result in an estimated 88°F perceived temperature.

As shown in the table below, heat indices meeting or exceeding 103 ° F can lead to dangerous heat disorders with prolonged exposure and/or physical activity in the heat. The heat index is a calculated temperature value of how hot it really feels when the amount of moisture in the air is factored in with the actual air temperature outside. This value is calculated by taking the relative humidity or dewpoint value for a specific location and factoring it into the air temperature reading.

In simplest terms, the heat index is the "feels-like" temperature, or how hot it really feels when the relative humidity is factored in with the actual air temperature.

The value of the HEAT INDEX tells you how hot it feels outside given the temperature and relative humidity.
