Feels Like Temperature shows what the outdoor temperature will feel like. It’s a collective
mixture of Wind Chill factor (18°C or below) and the Heat Index (26°C or above). For
temperatures in the region between 18.1°C to 25.9°C where both wind and humidity are less
significant in affecting the temperature, the device will show the actual outdoor measured
temperature as Feels Like Temperature.
