What to wear in Finland today – clothing advice from the weather now
Pick a town or use your location, and see what to wear right now: head, upper body, legs and shoes. The advice comes from the measured temperature, the feels-like temperature, wind, rain and UV, and it covers the next 12 hours too.
The current temperature is measured by the Finnish Meteorological Institute's stations within 25 km; the forecast, wind, rain and UV come from Open-Meteo and are adjusted to the measurement. Choose what you are doing outside (everyday, exercise, a long stay or with kids) and how well you tolerate cold, and the advice moves up or down a level. In winter the tool warns about frostbite risk from the wind chill, and in summer about heat and sun protection.
What should I wear in Finland in winter?
Dress in layers you can add or remove, and watch the wind: at −10 °C a wind of 10 m/s makes it feel like −20 °C. According to the Finnish Institute of Occupational Health, a wind chill of −25 °C is very cold, −35 °C brings a risk of frostbite and −60 °C a high risk. In summer, heat means over 25 °C (Finnish Meteorological Institute), and sun protection is needed from UV index 3 (STUK).

The cool, mild and warm limits at 10 and 18 °C are this tool's own rough split. Exercise lowers the advice by one level; a long stay outside or getting cold easily raises it by one.
Wind chill is calculated with the JAG/TI formula used by Environment Canada and the US National Weather Service.
