According to the Finnish Meteorological Institute's statistics, February was milder than usual and exceptionally mild in southern Finland. The average temperature varied between +2 degrees Celsius in the south-western archipelago and -10 degrees in Northern Lapland. Compared to the statistical reference period 1981–2010, the average temperature was, in general, 5–6 degrees higher than normal, while in Lapland, it was 2–4 degrees higher than normal.

The month's highest temperature, 9.0 °C, was measured at the Hammarland Märket station on 17 February. The lowest temperature of -32.3 °C was recorded at Sodankylä's Vuotso station on 26 February.

February was unusually rainy in many places and exceptionally rainy in some areas. Relative precipitation was the highest in southwestern Finland where precipitation levels were 2.5 times higher than typically in the reference period. Also in the area ranging from Kainuu to Southern Lapland, precipitation levels were, in places, twice as high as the reference period values. The month's initially highest precipitation of 123.2 mm was measured at the Leppäkorpi station in Lohja. The lowest precipitation, 21.9 mm, was recorded at the Näkkälä observation station in Enontekiö. The highest amount of precipitation within a 24-hour period, 38.9 mm, was measured at the Tapiola observation station in Espoo on 16 February. The precipitation level remained just a little over two millimetres short of the all-time February record.

In terms of snow cover, the country was divided in two: on the south side of the line between Oulu and the northern part of North Karelia, snow coverage was unusually or exceptionally low, whereas on the north side of the line, it was unusually or exceptionally high. The southern and western parts of the country were free of snow, but in Central Lapland, the snow level reached 110–120 cm in places.

Record-breakingly mild winter

Winter, i.e. the period from December to February, was exceptionally or record-breakingly mild in almost every part of the country except for Central and Northern Lapland. The deviation was the largest in the eastern part of the country where the winter was nearly 7 degrees warmer than usual. The smallest deviation was in Northern Lapland where the winter's average temperature was 2–3 degrees higher than usual.

In historical comparison, the entire country's average temperature ranked highest, surpassing the winter of 2007–2008. Comparable data for the whole country starts from the beginning of the 20th century.

With regard to rainfall, the winter was exceptionally rainy in many parts of southwestern and northern Finland with record-breaking precipitation in places. In the regions of Southwest Finland and Uusimaa, precipitation levels were generally over 250 mm which is over one-and-a-half times higher than typically in the reference period. The greatest deviation from the reference period values was recorded in Central Lapland where precipitation was, in places, twice as high as long-term averages.
