http://en.wikipedia.org/wiki/Humidex
The humidex 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 humidex is a unit-less number based on the dew point, but it is equivalent to dry temperature in degrees Celsius. For example, if the temperature is 30 °C (86 °F), and the calculated humidex is 40, then it indicates the humid heat feels approximately like a dry temperature of 40 °C (104 °F). The index is widely used in Canadian weather reports during summer.
According to the Meteorological Service of Canada, a humidex of at least 30 causes "some discomfort", at least 40 causes "great discomfort" and above 45 is "dangerous". When the humidex hits 54, heat stroke is imminent.
The current formula for determining the humidex (see below: Humidex formula) was developed by J.M. Masterton and F.A. Richardson of Canada's Atmospheric Environment Service in 1979. Humidex differs from the heat index used in the United States in being derived from the dew point rather than the relative humidity.
The record humidex in Canada occurred on July 25, 2007, when Carman, Manitoba hit 53.0.[1] This breaks the previous record of 52.1 set in 1953 in Windsor, Ontario (The residents of Windsor would not have known this at the time, since the humidex had yet to be invented).
