This autumn (September–November) was unusually or exceptionally warm almost throughout the whole country, with the exception of Lapland, according to the Finnish Meteorological Institute (FMI).
Many observation stations reported this as the second-warmest autumn on record. For example, this was the case at Jokioinen and Maaninka, in Kuopio, which both have nearly a hundred years of records. Utö, with 140 years of records, posted the third-warmest autumn ever.
The average temperature in the autumn varied from about zero degrees Celsius in north-west arm of Finnish Lapland to +10 degrees Celsius along the country’s southern coast.
The deviation of the mean temperature from the 1991–2020 reference period average was about one and a half degrees in Lapland, and over 2 degrees elsewhere.
The highest temperature of the autumn, 25.8 degrees celsius , was recorded at the Kärkkä observation station in Salo on 8 September.
The lowest temperature, minus 31.6 degrees Celsius, was measured at Enontekiö Airport on 24 November.
Precipitation this autumn was largely normal or slightly higher than normal.
The region form Kainuu to Southern Lapland saw significant rainfall, while the rainfall in the area close to the Eastern Border, in North and South Karelia, was less than average.
According to preliminary data, precipitation was the highest at the Paljakka observation station in Puolanka, where the precipitation level was 323.6 millimetres during September-November.
The lowest precipitation, 98.9 millimetres, was recorded at the Lintupuoliselkä station in Angeli, Inari.
November saw snowfall all the way in the south of Finland, but as the last week of November was mild, only Kainuu and Lappi retained a 10–25 centimetre snow cover.
In November, hours of sunshine ranged from one hour at Kevo in Utsjoki to approximately 48 hours at Badhusberget in Mariehamn. Apart from northern Lapland, Finland saw mostly normal hours of sunshine.
