Feels Like Temperature Calculator
Enter air temperature, humidity, and wind speed to calculate heat index or wind chill.
Results are planning references for outdoor activity. Sun exposure, clothing, activity, and health can change how the weather actually feels.

Heat index and wind chill use formula methods widely referenced by NOAA/National Weather Service.
Usage Tips
Check the apparent temperature before the air temperature
The same 30°C day can feel much hotter when humidity is high, and a freezing day can feel colder when the wind is strong. Before outdoor exercise, commuting, or travel plans, check humidity and wind speed together with the air temperature to understand how the weather will actually feel.
What is Feels Like Temperature Calculator?
The Feels Like Temperature Calculator estimates apparent temperature from air temperature, humidity, and wind speed. It selects a heat-index, wind-chill, or reference result for outdoor planning and does not diagnose personal health risk.
How to Use
- 1Choose Auto, Heat index, or Wind chill mode.
- 2Enter temperature, humidity, wind speed, and units.
- 3Review feels-like result, status label, and outdoor note, then copy.
Choose heat index or wind chill by its input conditions

heat feel = Heat Index(temperature°F, humidity); cold feel = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965TV^0.16
Heat Index uses Fahrenheit temperature and humidity, while Wind Chill uses Celsius temperature T and km/h wind V; unsupported conditions remain a reference temperature.
A hot 35°C day with 70% humidity
- • Temperature 35°C
- • Humidity 70%
- • Automatic mode
- 1. Convert 35°C to 95°F and meet the Heat Index condition
- 2. The calculated feel is about 50.34°C and the method is heat
At 35°C and 70% humidity, the tool uses Heat Index and reports a feel of about 50.34°C.
How to read the result
- High humidity slows sweat evaporation, while strong wind can increase heat loss in cold conditions.
- Automatic mode chooses heat, cold, or reference based on the supplied weather conditions.
Conditions that change the result
- Heat Index and Wind Chill are most meaningful within their supported temperature, humidity, and wind ranges.
- Clothing, direct sun, exercise, and health status can change how the same value feels.
Common input mistakes
- Do not force a heat formula on a cold windy day or a wind-chill formula on a hot humid day.
- A feels-like value is not a personal diagnosis of heat illness or hypothermia risk.
Reference Knowledge
- ●Feels-like temperature can change depending on humidity and wind speed.
- ●Heat feels-like temperature references Heat Index formula methods widely used by NOAA/National Weather Service.
- ●Cold feels-like temperature references Wind Chill formula methods used by National Weather Service.
- ●When conditions fall outside the formula range, the calculator shows a reference value close to the actual air temperature instead of forcing the formula.
- ●On hot days, high humidity can reduce sweat evaporation and make the air feel hotter.
- ●On cold days, stronger wind removes heat from the skin faster and makes it feel colder.
- ●The result is a planning reference and may vary depending on clothing, health, and activity level.
FAQ
Q.How do I use the feels-like temperature calculator?
Enter air temperature, humidity, and wind speed. The calculator estimates a heat index or wind chill depending on the conditions.
Q.Why does humidity matter?
On hot days, high humidity makes it harder for sweat to evaporate, so the air can feel hotter.
Q.Why does wind speed matter?
On cold days, wind removes heat from the skin faster, making the air feel colder.
Q.Are heat index and wind chill calculated differently?
Yes. Heat index mainly uses temperature and humidity, while wind chill mainly uses temperature and wind speed.
Q.Can the result differ from a weather app?
Yes. Weather apps may use different formulas, observation data, or local conditions, so this calculator is best used as a reference.
