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.
The lowest temperatures in winter are from -45Â°C to -50Â°C in Lapland and eastern Finland; from -35Â°C to -45Â°C elsewhere; and -25Â°C to -35Â°C in the islands and coastal regions. The lowest temperature recorded in Helsinki is -34.3Â°C (1987).
