Apparent temperature

Apparent temperature, also known as "feels like", is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature. Apparent temperature was invented by Robert G.

Steadman who published a paper about it in 1984.
It also applies, however, to indoor temperatures, especially saunas, and when houses and workplaces are not sufficiently heated or cooled.
The heat index and humidex measure the effect of humidity on the perception of temperatures above +27 °C (81 °F).
