'''Wind chill''' is the apparent temperature felt on exposed skin due to wind.
*The degree of this phenomenon depends on both air temperature and wind speed. The greatest wind chill reported in extremes, results from a combination of a low temperature and a high wind speed.
*The wind chill temperature (often popularly called the wind chill factor) is always lower than the air temperature. In cases where the apparent temperature is higher than the air temperature, the [[heat index]] is used instead.
Some weather stations provide a Wind Chill reading and, by default, that reading will be used by Cumulus.
#If within Cumulus you apply corrections (Configuration menu, ''Calibration'' screen) to either temperature or wind speed, then any wind chill output by your station will not be compatible, and you should set Cumulus to ''Calculate Wind Chill''.
#On Configuration menu click '''Station''' and tick the option to ''Calculate Wind Chill''.
*There may be other reasons why you do not want to use the reading provided by your station and tick this option.
*If your weather station does not provide a Wind Chill reading, Cumulus will calculate it (regardless of whether the option is ticked or not).

*For lower wind speeds, Cumulus will report a wind chill temperature that will be the same as reported for temperature.
*By default, for higher temperatures, Cumulus will
