"Feels Like" Temperature

The "feels like" temperature is a measurement of how hot or cold it really feels outside. The “Feels Like” temperature relies on environmental data including the ambient air temperature, relative humidity, and wind speed to determine how weather conditions feel to the bare skin. 

Different combinations of temperature, humidity, and wind speed can increase the sensation of being hot or cold. For example, skin that is exposed to wind and cold temperatures will make a person feel that it is colder outside than it really is because heat is drawn away from the body at a faster rate. As another example, a day that is very humid may feel hotter than it really is outside because your body sweat does not evaporate (and thereby cool the body) the way it is intended.
