Compared with long-term averages there was less snow than usual in all parts of the country at the end of the month, and in parts of Central Lapland the snow level was exceptionally low. In early to mid-March there was more snow than usual especially in central areas, but the long mild spell caused the snow to melt to below-average levels.
