The winter season 2019/2020 in Norway was as much as 4.5 degrees warmer than normal, and thus became the mildest since the Meteorological Institute started the measurements in 1900. The winter was also the second wettest.
Records in all regions in southern Norway
All regions except northern Norway set a record for the warmest winter season:
- Eastern Norway (Oslo, Viken, Innlandet and Vestfold and Telemark) had an average temperature from December to February of 5.7 degrees over the normal period 1961-1990. The previous record is from 1988/89, and was 5.2 degrees above normal.

Second wettest winter measured

Several stations in Western Norway, the Inland and Troms and Finnmark received from 250 to over 300 per cent of the normal. Some stations in the hinterland and Troms and Finnmark received from 75 per cent to just under 100 per cent of the normal precipitation.
