Finland recorded its second warmest year on record in 2025, with temperatures across most of the country only slightly below the record set in 2020, the Finnish Meteorological Institute (FMI) said in its annual climate report released on Wednesday, reported Xinhua. The nationwide annual mean temperature was 4.5 degrees Celsius, 1.6 degrees Celsius above the 1991-2020 long-term average, the report said, noting that the warmest year on record was 2020, when the nationwide annual mean temperature was 4.8 degrees Celsius. Most weather stations reported annual mean temperatures 1 to 2 degrees Celsius above average, and station-specific annual means were generally the second highest on record, the FMI noted. Last year's highest temperature was 32.6 degrees Celsius, measured at Oulu Airport in northern Finland on July 31, while the lowest was minus 39.6 degrees Celsius at the Tulppio observation station in Savukoski, a town in northeastern Lapland, on Feb. 4. All months were warmer than usual nationwide except May, June and August, the FMI said. September was record warm for a third straight year, following record-warm Septembers in 2023 and 2024. Last year began with broadly milder-than-usual weather, and spring arrived early in parts of Finland. March was record warm in places along the western and southwestern coasts, the FMI said, though cooler and more unsettled periods in late spring and early summer left May and June slightly cooler than usual. The FMI said its meteorological observations date back to the mid-19th century, and that some observation series published through its open data service can be traced back to 1844.
