The climate in Finland can be classified as a boreal climate or a subarctic climate. This type of climate is characterized by long, cold winters and short, mild summers. The country's northern location and the influence of the Atlantic Ocean and the Baltic Sea are important factors influencing Finland's climate.

Southern Finland

In southern Finland, including the capital Helsinki, winters are milder compared to the rest of the country, with average temperatures around -5 degrees Celsius and snowfall of about 20 to 30 cm. Summers are pleasantly warm with averages around 20 degrees Celsius. Precipitation is fairly evenly distributed throughout the year, with an annual amount of about 600 to 700 mm and a slight peak in the summer months.

West Finland

West Finland, with cities such as Turku and Tampere, has similar temperatures to southern Finland, but with slightly more precipitation, about 700 to 800 mm per year. Snowfall here is around 20 to 40 cm. This is due to its proximity to the sea, which provides more moisture in the air.

Eastern Finland

In Eastern Finland, including cities such as Joensuu and Kuopio, winters are slightly harsher with temperatures that can drop to -20 degrees Celsius and snowfall of around 30 to 50 cm. Summers are slightly cooler than in the south and west. Precipitation is also slightly lower here, with about 600 to 700 mm annually.


Lapland, in northern Finland, has a subarctic climate. Winters are long and severe with temperatures often dipping below -20 degrees Celsius and snowfall that can reach 60 to 90 cm, sometimes even over 100 cm in some areas. Summer is short but surprisingly mild, with temperatures sometimes reaching 20 degrees Celsius. Precipitation here is the lowest in Finland, with about 500 to 600 mm per year.

Åland Islands

The Åland Islands, located in the Baltic Sea, have a slightly milder maritime climate. Winters here are less severe, with average temperatures of -3 to 1 degrees Celsius and snowfall of about 10 to 30 cm. Summers are cool and pleasant with average temperatures of 15 to 20 degrees Celsius. These islands receive about 500 to 600 mm of precipitation annually and more sunshine hours than the rest of Finland, especially in the summer.

The climate in Finland is thus very diverse, with significant differences between different regions. These variations are largely due to the geographical distribution of the country, the influence of the surrounding seas and the northern latitude.
