Wind chill involves measuring the temperature as it is felt on the skin, which is determined by the air temperature and wind speed. The Bureau of Meteorology (BOM) has a mathematical equation to estimate what it actually feels like for an average person outside. For example, when the air temp is 90F but the humidity is at 35%, the dry conditions will make the "feels like" temperature roughly equal. The "Feels Like" temperature relies on environmental data including the ambient air temperature, relative humidity, and wind speed to determine how weather conditions feel to bare skin.
