HEAT INDEX °F (°C) The heat index is an accurate measure of how hot it really feels when the affects of humidity are added to high temperature. RELATIVE HUMIDITY (%)
The ‘Heat Index’ is a measure of how hot weather "feels" to the body. This table uses relative humidity and air temperature to produce the "apparent temperature" or the temperature the body "feels".
Heat index chart. In order to determine the heat index using the chart above, you need to know the air temperature and the relative humidity. For example, if the air temperature is 100 ° F and the relative humidity is 55%, the heat index will be 124 ° F.
To find the Heat Index temperature, look at the Heat Index Chart above or check our Heat Index Calculator. As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index--how hot it feels--is 121°F. The red area without numbers indicates extreme danger.
Heat Index Chart and Explanation. WPC Heat Index Forecasts More Meteorological Conversions and Calculations
Calculate the heat index from the temperature and humidity (either relative humidity or dew point), or use a simple heat-index conversion chart.

An interactive, hourly forecast of heat index values, risk levels, and recommendations for planning outdoor work activities.
The chart shows the Heat Index - how hot it feels - as 109°F (43°C), which is in the orange range for DANGER. Remember, these values are in the SHADE. You can add up to 15°F (8°C) to these values if you are in direct sunlight.
