October 2025 was warmer than normal throughout Finland, with some parts of the country recording temperatures significantly higher than long-term averages, according to the Finnish Meteorological Institute.
Monthly average temperatures ranged from around +1.5°C in Enontekiö, located in the far north, to roughly +10°C in the southwest archipelago. Across the country, temperatures were 1°C to 3.5°C above the 1991–2020 reference period.
In Lapland, the month was classified as unusually warm. The first snow in the north fell more than two weeks later than usual.
In Kilpisjärvi, located in Enontekiö, measurable snowfall was recorded on 16 October. Snow coverage remained patchy for the rest of the month, with only isolated areas of snow in northern Lapland by the end of October. The greatest recorded snow depth was 17 centimetres, measured in Kilpisjärvi on 24 October.
The highest temperature of the month, 15.7°C, was measured on 6 October at the Vänö weather station in Kemiönsaari. The lowest, –13.4°C, was recorded on 21 October in both Oustajärvi, Muonio and at Enontekiö Airport.
Rainfall varied across the country. Eastern and southern Finland received less precipitation than normal, while the western coast and parts of northern Finland recorded slightly higher-than-average levels. The highest monthly total was 114.6 millimetres in Kaakkuri, Tornio. The lowest was 30.3 millimetres in Mekrijärvi, Ilomantsi. The heaviest one-day rainfall was also measured in Tornio, with 30.2 millimetres falling on 23 October.
Sunshine hours ranged from 30 to 70 in most regions, and from 70 to 110 in the west. Across much of the country, the total number of sunshine hours was slightly below average for October.
The data confirm a continuation of the pattern of warming autumns in the region. Although no monthly records were broken, the delayed snowfall and higher-than-average temperatures in the north marked a clear departure from typical late-autumn conditions.
