According to the Finnish Meteorological Institute's statistics, the average temperature in November was about one degree lower than usual in the southern and central parts of the country, while it was one degree higher than usual in Northern Lapland.

November was, however, divided into two distinctly different periods in terms of temperature. During the first half of the month, a north-easterly air current that was unusually or even exceptionally cold regarding the time of the year prevailed in Finland. At the same time, snow depth increased to as much as 20–30 cm in places in the southern and eastern parts of the country. During the latter half of the month, on the other hand, a mild south-westerly current prevailed in Finland and the snowline retreated to Northern Ostrobothnia.

The lowest temperature in November, -24.7°C, was recorded in Sodankylä on the 29 November, and the highest temperature, +8.5°C, in Pori and Lumparland on 21 November.

The month's total amount of precipitation was higher than usual in the central part of the country and in Western Lapland, whereas the rest of the country was close to the levels in long-term statistics. The highest amount of precipitation in November, 103.2 mm, was recorded in Aapajärvi, Tornio. The highest amount of precipitation within a 24-hour period, 30.5 mm, was measured in Kärjenkoski, Isojoki on the 18 November. 

The autumn was fairly dry

The average temperatures of the autumn, i.e. the period ranging from September to November, were close to the usual temperatures in the southern and central parts of Finland, whereas Lapland was 1–2 degrees warmer than usual. The temperatures in Central and Northern Lapland were even unusually warm in places, which means that an autumn as warm as this occurs once in ten years or even less frequently.

The autumn was drier than average in a large part of the country. Precipitation levels in the area ranging from the southwestern part of the country to Southern Lapland were largely unusually low, and the autumn was the driest in records at some measurement stations in Southwestern Finland. The lowest levels of precipitation were recorded in Nuorgam, Utsjoki, where the total amount of precipitation received in three months was 62 mm. The eastern part of the country received the most precipitation. The highest amount of precipitation, 238.3 mm, was measured in Vironlahti.
