Sign in to savethumb|upright=2|Plot of humidex depending on temperature and relative humidity The humidex (short for humidity index) is an index number used by Canadian meteorologists to describe how hot the weather feels to the average person, by combining the effect of heat and humidity. The term humidex was coined in 1965. The humidex is a nominally dimensionless quantity (though generally recognized by the public as equivalent to the degree Celsius) based on the dew point.

Range of humidex: Scale of comfort 20 to 29: Little to no discomfort 30 to 39: Some discomfort 40 to 45: Great discomfort; avoid exertion Above 45: Dangerous; heat stroke quite possible
