Finland Weather and Climate

Finland has a reputation as a land of ice and snow, but summers are warm and sunny, with daytime temperatures reaching 25-30ºC (77-86˚F), and even spring and autumn can be surprisingly mild. The sun never truly sets in midsummer and locals take full advantage of the midnight sun for late-night sports, barbecues and parties. Finland only really deserves its frosty reputation in winter, from November to mid March, when temperatures plummet to -20ºC/-4ºF 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. Rainfall is distributed fairly evenly throughout the rest of the year. During June and July, forested areas are plagued by gnats and mosquitoes, particularly in the north of the country. Bring plenty of insect repellent.

In summer, travellers can get away with lightweight clothing in the daytime, but long sleeves and long trousers or skirts are useful for the evenings. Waterproof clothes are useful throughout the year. A netting veil is useful when trekking in the mosquito season. In winter, bring appropriate clothing for snowy conditions. In the Arctic North, you may need expedition-quality winter clothing.
