Snow statistics
When is the ground first covered with snow and when is it permanent?
The very first snowflakes fall to the ground in late August or early September over the higher peaks in Lapland. The first ground-covering snow and permanent snow cover arrive at different times in different parts of the country. In Lapland the winter is long (approximately seven months) and the permanent snow cover comes significantly earlier than in southern Finland.

When does the snow cover melt away?
The snow cover is usually thickest at mid March, in Lapland often as late as early April. Soon after that the snow cover starts to melt fast.
