According to the statistics of the Finnish Meteorological Institute, October was exceptionally warm in most parts of the country. Such warm October occurs on average once every 10–20 years. The monthly mean temperature varied between approximately 10 degrees Celsius in the southern coast, to just under two degrees in northern Lapland. The deviation from the long-term average temperatures (1981–2010) was around 2.5°C in most parts of the country.

The first half of the month was very warm, while after mid-month there was a week's period of colder than usual weather. During this week, the first snow arrived in many parts of Northern Finland, as well as in parts of Central Finland. Towards the end of October, temperatures rose again to high levels compared to the seasonal average. Therefore, the last days of October saw significant amounts of snow only in the northernmost Lapland.

The highest temperature of the month was 18.7°C, recorded in Anjala, Kouvola, on the 5th. In comparison, the lowest temperature, -20.5°C, was recorded in Enontekiö airport, on 31 October.
