Feels-Like Temperature Calculator
Get the single 'real feel' temperature your weather app shows — it switches between wind chill and heat index depending on the conditions.
This picks the right “feels like” formula for you: wind chill when it’s cold and breezy, heat index when it’s hot and humid, and the plain air temperature in between — the same logic weather apps use.
How it works
Your body's comfort depends on more than the thermometer. In the cold, wind matters most; in the heat, humidity does. The feels-like temperature blends the right factor for the moment into one honest number.
This calculator does the choosing for you. When it's 50°F (10°C) or colder with wind above 3 mph, it uses the NWS wind chill. When it's 80°F (27°C) or hotter, it switches to the heat index. In the mild middle, it just reports the actual air temperature.
Enter the temperature, relative humidity, and wind speed, and the tool tells you both the feels-like value and which method it used — so you can see exactly why a 35°F windy morning feels closer to 25°F.
Frequently asked questions
Why does the feels-like number sometimes equal the actual temperature?
In mild, calm conditions — think a still 65°F afternoon — neither wind chill nor the heat index applies. There's nothing to adjust for, so the feels-like temperature is simply the air temperature.
How does this pick between wind chill and heat index?
It follows the standard cutoffs: wind chill kicks in at or below 50°F with real wind, and the heat index kicks in at or above 80°F. Those are the ranges where each formula is valid, so you always get the appropriate one.
Is 'feels like' the same as 'real feel'?
Basically, yes. Different apps brand it as 'feels like,' 'real feel,' or 'apparent temperature,' but they all mean an estimate of how the combination of heat, humidity, and wind registers to your body.
