According to statistics compiled by the Finnish Meteorological Institute, March was 1 to 2 degrees milder than average in many parts of the country. However, such a mild March is not rare, but occurs on average more than once in a decade. The monthly average temperature was close to or slightly below normal only in Central and Northern Lapland.
The highest temperature in March was 13.4°C, recorded in Jomala, Ahvenanmaa on 29 March. The lowest temperature was -37.9°C, recorded in Kevojärvi, Utsjoki on 2 March.
East and north had an exceptional amount of precipitation
Several low-pressure areas moved over our country in March. This means that precipitation was heavier than usual in large parts of the country. In the east and north, monthly precipitation was unusually high in places – that is, a similar amount occurs less frequently than once every 30 years. The heaviest precipitation level for March in the station's measuring history spanning over 100 years, 66.6 mm, was recorded in Tähtelä, Sodankylä. The month's highest precipitation level of 85.3 mm was recorded in Paljakka, Puolanka. Kevo, Utsjoki had the lowest monthly precipitation level of 11.0 mm.
At the end of the month, the zone reaching from Northern Karelia to Lapland had, in general, between half a metre and one metre of snow, and the rest of the country, mostly 10–50 cm. Areas near the southern and western coastline were free of snow in many places. At the end of the month, snow depth was lower than usual in large parts of the country.

The weather is rarely exceptional. Meteorologists use the word ‘exceptional' only when a weather phenomenon occurs on average only three times or less within one hundred years. A weather phenomenon is called rare only when it occurs less than once in ten years.
