Finland only really deserves its frosty reputation in winter, from November to mid March, when temperatures plummet to -20ÂºC/-4ÂºF or lower. Winter days are short and in Lapland, the sun may not clear the horizon at all. In the far north, the snow cover can last from as early as October till as late as May.
In winter, northern Finland is covered by snow from November to April. In the south, the snow usually arrives in December-but the amount of snowfall may vary from one year to another. North of the Arctic Circle, the winter includes a period known as the polar night, when the sun does not rise above the horizon at all. In the northernmost extremity of Finland, the polar night lasts for 51 days. In southern Finland, the shortest day is about 6 hours long. In winter, temperatures of -20Â°C are not uncommon in many areas. The average temperature in Helsinki in July is +17Â°C and in February -5,7Â°C. Obviously, the winter temperatures in Finnish Lapland can be much lower.
