The feels like temperature is a single number that tells you how the weather actually registers on your body once wind and humidity are taken into account. In warm weather high humidity slows evaporation and makes it feel hotter, so this tool applies the National Weather Service heat index. In cold weather wind accelerates heat loss and makes it feel colder, so it switches to the 2001 wind chill formula. In the mild middle range where neither strongly applies, the feels like value is simply the air temperature. Enter the temperature, the relative humidity and the wind speed, choose your unit system, and the calculator automatically picks the correct model and shows the apparent temperature with a short comfort note. This mirrors how weather apps compute their real feel figure. Everything runs locally in your browser, so results are instant and private.
