According to the statistics of the Finnish Meteorological Institute, this autumn (September–November) was the warmest in measurement history in many southern and western parts of the country. In other parts of the country, the autumn was mostly unusually warm, and in some places exceptionally warm. The average temperature during the autumn varied from just over 10 degrees in the south-western archipelago to just under 2 degrees in Northern Lapland. Compared to the statistical reference period 1981-2010, the temperatures in the whole country were around three degrees higher than the long-term average.
The highest temperature of the autumn, 23.5 degrees, was recorded at the Tulkkila observation station in Kokemäki on 27 September. The coldest temperature, -21.6 degrees, was measured in Pokka, Kittilä, on 27 August.
The autumn saw high levels of precipitation, especially in central Finland. The highest levels were measured in the provinces of the West Coast, North Ostrobothnia, Kainuu and Southern Lapland, where the precipitation levels were exceptionally high. In the southern and central parts of the country, the precipitation levels during the autumn were mainly normal or above average. In Central Lapland, precipitation levels were lower than average, and the regions of Utsjoki and Inari saw in places unusually low precipitation levels.
According to preliminary data, the highest precipitation level recorded for the period September–November was at the Paljakka observation station in Kainuu, where the total reached 408.3 mm. The lowest level of precipitation, at 62.4 mm, was recorded at the Kevo observation station in Utsjoki.
Monthly temperature record broken for November

In southern and central parts of the country, record-breaking monthly average temperatures were measured at some observation stations. The average temperature in November varied between approximately 7 degrees in the south-western archipelago and -2 degrees in Northern Lapland. The deviation from the statistical reference period was around 4–6 degrees, with the largest deviations being seen in Lapland.
In the first week of the month, the highest temperature ever recorded for November was obtained at Jomala Mariehamn Airport, where the temperature reached 16.6 degrees on 6 November. The month's lowest temperature, -21.6 degrees, was recorded in Pokka, Kittilä, on 27 November.

The month’s highest precipitation level, 146.1 mm, was measured at Paljakka observation station in Puolanka. The lowest level of precipitation, at just 10.6 millimetres, was measured at the Kirakkajärvi observation station in Angeli, Inari. The month’s highest level of precipitation within a 24-hour period, at 51.7 millimetres, was measured at the Kemijärvi Airport observation station on 2 November.
