Which Scandinavian country is the coldest?

Weather in Finland

Finland lies in the cold-temperate climate zone and the weather is shaped by maritime and continental influences. With westerly winds, low pressure areas approaching from the Atlantic ensure changeable weather. On the other hand, stable high-pressure bridges that extend from mainland Russia ensure cold, dry winters and warm summers. In Helsinki, the summer highs regularly rise to more than 20 ° C.

The land mass of Finland extends between the 60th and 70th parallel and the north-south extension is more than 1,000 kilometers. This results in a clear temperature gradient between the southern parts of the country and the north. While the annual average temperature in the south is +5 ° C, it only reaches -2 ° C above the Arctic Circle in Finnish Lapland. The differences in the length of winter are correspondingly large. In the north, the country is buried under a thick layer of snow for around 200 days, while in the western Finnish archipelago it is 100 days less.

In winter, a closed snow cover forms across the country, reaching a thickness of 20-30 cm in the south and 60-90 cm in the north. The inland lakes freeze over by December at the latest and only thaw again in May. It is not uncommon for the Gulf of Finland and Bothnia to freeze over and the ports have to be kept free of icebreakers. The Finnish cold record is held by the municipality of Pokka in the Kittilä region. On January 28, 1999, -51.5 ° C was measured here.

Summers are short in Finland and last from June to August in the north of the country and from late May to mid-September in southern Finland. In the capital Helsinki, the daytime temperatures in July and August are over 20 ° C and up to 15 summer days are counted annually on which the temperature reaches values ​​of 25 ° C and more. Especially in inland Finland it can get up to 30 ° C under stable high pressure in summer. The front runner in summer highs is the place Liperi, where on July 28, 2010 a maximum temperature of 37.2 ° C was measured.

The following overview refers to the weather in the Finnish capital Helsinki in southern Finland.
