Comfort
What the weather actually feels like
What is it?
Comfort combines temperature, humidity and wind into the apparent ('feels-like') temperature. Humidity blocks sweat evaporation and makes heat feel hotter; wind strips body heat and makes cold feel colder.
How we measure it
Open-Meteo's apparent temperature for the current hour, classified into comfort bands together with humidity. The classification is computed and labeled as such.
Feels-like temperature bands
- < 5°CColdLayer up; wind chill matters
- 5–16°CCoolLight jacket weather
- 16–27°CComfortableIdeal for most activity
- 27–33°CWarmHydrate during exertion
- 33–41°CHotHeat exhaustion possible with exertion
- > 41°CDangerous heatHeatstroke risk — limit exposure
Within safe range
In the 16–27°C feels-like band, the body regulates temperature effortlessly — the sweet spot for sport, work and travel.
Beyond the range
Outside it, physiological stress rises on both ends: above ~33°C feels-like, core temperature control starts to strain (see Heatwave guide); below ~5°C with wind, exposed skin loses heat fast (see Coldwave guide). Dress and plan for the feels-like number, not the thermometer.
Precautions
- Always check feels-like before choosing clothing or planning exertion.
- Hot + humid: shift activity to early morning; hydrate before you feel thirsty.
- Cold + windy: cover extremities; wind chill accelerates frostbite.
- Children, the elderly, and outdoor workers hit limits earlier — build in breaks.
