Heat Index combines the effects of heat and humidity.  Heat index will be the same number as the Outdoor Temperature until the outdoor temperature is above 26.7 degrees C (80 degrees F).

Dew Point Temperature:
Dew Point Temperature is the saturation point of the air, or the temperature to which the air must cool to create condensation.  The higher the dew points, the higher the moisture content of the air at a given temperature.  Dew Point is lower than the actual temperature.
