January weather forecast
Finland

January is typically the coldest month in Finland, marking the peak of the harsh winter season. During this month, temperatures can fall as low as -50°C (-58°F) in the northernmost region of Lapland, as recorded in Kittila. In the less extreme areas, January temperatures commonly dip below -20°C (-4°F). The country is fully in the grip of winter during this month, and daylight is scarce, especially in the northern regions.

Polar nights dominate the extreme north, including the region of Lapland. Here, the sun does not rise above the horizon for days, and the darkness is pierced only by the ethereal glow of the Aurora Borealis. In contrast, the southern parts of Finland experience shorter days, but the sun does make a brief appearance, offering a small reprieve from the polar nights experienced in the north.

Despite the cold from the Eurasian high-pressure system, the Gulf Stream and North Atlantic Drift currents moderate the winter temperatures, preventing them from becoming excessively cold. Consequently, coastal cities like Helsinki, on the southern coast, experience slightly milder winters compared to inland cities such as Rovaniemi in Lapland.

January follows the windiest period of the year, which typically runs from October to December. Therefore, wind speeds start to decrease during this month, and stormy days are less frequent compared to the previous months.

Regarding precipitation, January sees a significant portion of it falling as snow, covering the entire country in a thick blanket of white. This month signals the beginning of the period of permanent snow cover, which varies from 203mm (7.99") in the south to 610mm (24.02") in the north.

Comparatively, February sees a slight increase in temperatures and daylight hours. However, snowfall remains abundant throughout the country, with the north receiving the highest amounts, setting the stage for winter activities and tourism.
