A significant, previously unknown population of freshwater pearl mussel was found in the Ivalojoki watershed in Finnish Lapland. The cooperative Lumimuutos discovered it during restoration work in the Sámi homeland in summer 2025; authorities are withholding the exact location.

Temperatures fell to -29.5°C in Vuotso, Sodankylä, the coldest reading so far this winter in Finland. Other Lapland sites also saw severe cold, and November is running much colder than normal.

On August 2, 2025 multiple wildfires broke out in Lapland’s Ranua and Posio areas, with additional fires reported in Tervola, Sodankylä, Rovaniemi and Kolar. The largest wildfire, spanning 500 × 500 m, burned near Alavaarantie in Ranua by late afternoon.

Recent heat waves have warmed Lapland’s rivers and lakes, leading Metsähallitus to suspend fishing permits and advise against salmonid fishing in the warm waters.

Lake and river surface waters in Lapland have warmed rapidly due to recent heatwaves, reaching up to 5°C above average and attracting more beach visitors than usual.

Powder on the ground is nearly one meter deep in some parts of Finland's northernmost region.

Dozens of moose carcasses were discovered last spring in a Lapland national park, and Finland animal disease watchdog Evira has since determined that the animals died of malnutrition. The reason why they were unable to find sustenance is a mystery, as the area had relatively normal temperatures and snowfall last winter.

The skiing season ended in Northern Lapland in mid-May, but the weather there is still so cold and snowfall so frequent that the Saariselkä resort will temporarily reopen its slopes, which are currently up to a metre deep in snow.
