November temperatures were close to normal, precipitation remained low
According to the Finnish Meteorological Institute’s statistics, the weather in November was normal or slightly milder than normal in most of the country. The average temperature for the month ranged from about +6 degrees in the Southwestern Archipelago to -7 degrees in Enontekiö. The average temperature was mostly 0.5‒1.5 degrees above the average for the 1991–2020 normal period. Similar Novembers are experienced several times a decade, which means that this year’s November was very close to typical temperatures.
The highest temperature of the month, 15.1 degrees, was recorded at Jomalaby in Jomala on 12 November. The lowest temperature of the month, -26 degrees, was recorded at Vuotso in Sodankylä on 21 November.
Precipitation levels remained low in most parts of the country
In the southern and central parts of the country, November’s precipitation levels were lower than usual or close to the monthly average in many places. In the southern part, the precipitation level was exceptionally low in some places. In the northern part of the country, precipitation levels were also exceptionally low for the most part. According to preliminary data, precipitation in November was heaviest at Ylä-Luosta in Rautavaara, at 73 millimetres. Precipitation was lowest at the Kilpisjärvi village observation station, at 12.2 millimetres. The greatest amount of precipitation in a single day, 23.2 millimetres, was recorded at the Ylä-Luosta observation station in Rautavaara on November 11.
At the end of November, most of the country had snow from a few centimetres to ten centimetres. There was 10–25 centimetres of snow in Central and Northern Lapland. In the south, some parts had slightly more snow than usual for the time of the year. In the central and northern parts of the country, many parts had less snow than usual, and some parts of Lapland had exceptionally low amount of snow.
Observation stations recorded an unusually low number of hours with sunshine, and exceptionally low numbers were recorded in some places.
Autumn was mild and precipitation remained low
The average temperature for the autumn (September–November) in general ranged from about 0 degrees in the northwest of Finnish Lapland to about +9 degrees in the Southwestern Archipelago. In most parts of the country, the autumn was 0.1–1 degree warmer than usual. Similar autumn temperatures are experienced several times a decade.
The highest temperature of the autumn, 19.5 degrees, was recorded at Jussarö in Raseborg on 6 September. The lowest temperature, -26 degrees, was measured at Vuotso in Sodankylä on 21 November.
Autumn precipitation levels remained lower than usual in most of the country. In many places, precipitation levels were exceptionally low, which means that similar precipitation levels occur less frequently than once every ten years.
According to preliminary data, precipitation was the highest at the Paljakka observation station in Puolanka where the precipitation level was 213.6 millimetres in the September-November period. The lowest amount of precipitation, 71.8 millimetres, was recorded at the Kevo observation station in Utsjoki.
