What is humidex?
It describes how the weather feels to the average person. See more details here:
Mike, I did not ask the exact question I meant to ask - why the difference between the Humidex and “Feels Like” temperatures. Do the Canadians just do it differently than we do?
The feels like temperature shows the heat index (a combination of temperature & relative humidity) for higher (warmer) temperatures or the wind chill (a combination of temperature & wind speed) for lower (cooler) temperatures.
The humidex is equivalent to the heat index.
