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.
Summer. In summer the mean daily temperature is consistently above 10Â°C. Summer usually begins in late May in southern Finland and lasts until mid-September. Summer in Lapland starts about one month later and ends a month earlier than the south coast. The regions north of the Arctic Circle are characterized by polar days, when the sun does not set at all. The northernmost parts of Finland have 73 such days every year.
