How windy is Finland in 2026?

FMI climate guidance puts average wind speed between about 2.5 and 4 m/s inland, slightly higher on the coast, and about 5 to 7 m/s in maritime regions. Speeds are typically highest in winter and lowest in summer. Across the country the wind blows most often from the southwest.

The Archipelago Sea, Utö-class outer islands, and open Gulf of Finland or Gulf of Bothnia shores feel the maritime band first. Turku and southwest coast day trips meet that exposure quickly: Living in Turku. Helsinki shoreline neighbourhoods feel rawer than inland Espoo courtyards on the same frontal day: Living in Helsinki.

Inland lake cities such as Tampere usually sit in the calmer inland band, though open ridges still catch fronts: Living in Tampere. Northern coastal and fell-edge sites can also run windier than deep forest valleys; Oulu’s shore days feel different from a sheltered inland yard: Living in Oulu.

FMI notes that storms above 20 m/s occur a few times every month on the open sea in autumn and winter, while inland storms stay rare. thisisFINLAND flags November as a classic sea-storm month, with roughly a handful of stormy days on Finnish sea areas rather than constant gales. Pair that with rain and raw damp: Rain and Humidity.

Summer brings lighter winds overall, plus a coastal sea breeze that can push 10 to 20 km inland from the Gulf of Finland or Gulf of Bothnia. Thunderstorms still throw strong local gusts on inland lake afternoons: Summer heat. Winter wind makes 0 to –10°C feel much colder on Helsinki’s shore and pairs with ice after thaw: Winter cold and Snow.
