Surviving Finnish Winter
Your guide to Finnish winter
Finnish winters are long, cold, and dark — but they can also be magical. In northern Finland, the polar night (kaamos) means the sun doesn't rise for weeks, while even Helsinki sees only about 6 hours of daylight in December. Temperatures regularly drop to -20°C or below in Lapland, though southern Finland averages around -5°C to -10°C. Understanding how to dress, stay active, and take care of your mental health during winter is essential for thriving as an international worker in Finland.
- Polar night (kaamos) brings extended darkness from November to January
- Temperatures range from -5°C in Helsinki to -30°C in Lapland
- Proper layering and winter gear make all the difference
Dealing with darkness and kaamos
The limited daylight during Finnish winter is often the biggest challenge for newcomers. In Helsinki, December days have roughly 6 hours of light, while in Rovaniemi the sun barely rises at all.
- Invest in a 10,000-lux light therapy lamp and use it for 30 minutes each morning to regulate your circadian rhythm
- Take vitamin D supplements throughout the dark months - Ruokavirasto recommends a daily supplement year-round if you do not regularly eat vitamin D-fortified products or fish (about 10 µg/day for adults, up to 20 µg/day for people aged 75+)
- Make the most of available daylight by scheduling outdoor walks during lunch breaks
- Keep your home well-lit with warm lighting — many Finns use candles and string lights throughout winter
Winter clothing and layering
The Finnish saying 'there's no bad weather, only bad clothing' (ei ole huonoa säätä, on vain huonoja vaatteita) is taken seriously. Proper layering is the key to staying comfortable.
- Base layer: merino wool or synthetic moisture-wicking thermal underwear is essential for daily commutes
- Mid layer: fleece or wool sweater provides insulation — avoid cotton which retains moisture
- Outer layer: a windproof and waterproof winter jacket rated to at least -20°C from brands like Halti, Icepeak, or Reima
- Footwear: insulated winter boots with non-slip soles (nastakengät or liukuesteet) — Kuoma and Sorel are popular choices
Winter activities and recreation
Finns embrace winter with a wide range of outdoor activities. Participating in these is one of the best ways to enjoy the season and connect with locals.
- Cross-country skiing (hiihto) is Finland's national winter sport — most cities maintain groomed tracks that are free to use
- Ice skating on frozen lakes and maintained outdoor rinks is popular from December through March
- Ice swimming (avanto) combined with sauna is a beloved Finnish tradition that boosts mood and circulation
- Downhill skiing and snowboarding at resorts like Levi, Ruka, and Ylläs in Lapland offer affordable season passes
Practical winter survival tips
Beyond clothing and activities, there are practical considerations for navigating daily life during Finnish winter that every newcomer should know.
- Keep your phone battery warm — cold drains batteries fast, so carry your phone in an inner pocket
- Allow extra commute time as buses and trains may face delays during heavy snowfall or extreme cold
- Use studded tires (nastarenkaat) if you drive — winter tires are legally required from November to March
- Stock up on essential supplies before major storms — Finnish weather service (Ilmatieteen laitos) provides reliable forecasts
Winter well-being tips
Taking care of yourself during the dark months is crucial for long-term happiness in Finland.
- Join a sports club or gym to maintain regular exercise habits when outdoor activity feels harder
- Maintain social connections actively — winter isolation is real, so schedule regular meetups with friends
- Embrace hygge-like Finnish coziness (kotoilu) — warm drinks, blankets, and good company make winter evenings enjoyable
