Warm spring air pushes temperatures toward 10°C this weekend as Finland experiences one of its first true signs of spring this year. The Finnish Meteorological Institute reports that a surge of mild air and sunshine will lift daytime temperatures above freezing across most of the country, including Lapland.
Forecasters say the warmest conditions will appear in southern and western Finland, with Sunday expected to deliver the highest readings. Meteorologist Janika Takala noted that temperatures reaching this level so early in the year are unusual, as such warmth typically occurs closer to the end of April. Across large areas, temperatures between five and ten degrees Celsius are expected, with local peaks near 10°C in southwestern inland regions and the Tornio valley.
The warming comes from a dry, mild airflow from the west. Foreca meteorologist Joanna Rinne explained that a strengthening high-pressure system over central Europe is sending winds across the Norwegian mountains, creating a föhn effect that raises temperatures as the air descends toward Finland. As a result, daytime temperatures in southern and central regions will remain above zero through the end of the week, while northern Finland will see positive readings from Friday onward. Nights will still drop below freezing in most areas, though southern Finland may experience slightly milder nights.
Sunshine will dominate much of the country this weekend, though northern areas will see variable clouds and the chance of light snow in eastern Lapland. The rising temperatures and bright skies are accelerating snow melt. Measurements already show bare ground in parts of southwestern Finland and the Åland Islands, while snow cover in southern and western regions generally ranges from five to twenty centimetres. In northern Finland, snow still measures sixty to eighty centimetres, but the combination of sun and warmth will shrink the snowpack quickly in the coming days.
The drying ground also signals the early start of Finland’s wildfire warning season. Authorities expect initial warnings within a few weeks if dry weather continues, particularly in Åland and southwestern Finland where snow has largely disappeared.
Signs of warming are already evident. On Wednesday, the highest temperature of the year reached 7.5°C at the Jomalaby observation station in Jomala on the Åland Islands. While most of the country enjoys these spring conditions, northern regions face continued risks. The Finnish Meteorological Institute reports elevated avalanche danger in several fell areas of Lapland, including Kilpisjärvi and Saariselkä, with a level three rating on the five-level scale indicating considerable risk on natural slopes. These warnings do not apply to maintained ski slopes.
