Why is wind chill not always indicated in the current conditions or in the forecast?
Wind chill is indicated in current conditions only when the temperature is 0C or lower, with a wind speed of 2 km/h or more. In general, wind chill is mentioned in a forecast only if it is expected to be significant, that is to say, if wind chill is expected to be -25 or colder, with a forecast wind speed greater than 10 km/h.
