= Humidex
{wiki=Humidex}
Humidex is a Canadian invention that combines the effects of heat and humidity into a single value, providing a measure of perceived temperature. The term is a portmanteau of "humidity" and "index." It is particularly useful in describing how hot and uncomfortable the weather feels, especially during summer months when both temperature and humidity are high. The Humidex is calculated using the air temperature and the dew point (a measure of humidity).
