December weather forecast
Finland

December ushers in the heart of the Finnish winter, with freezing temperatures, heavy snowfall, and minimal daylight. Temperatures across the country typically range from -10°C (14°F) in the north to 0°C (32°F) in the south. Northern regions, particularly Lapland, endure the brunt of the harsh winter conditions.

Southern cities such as Helsinki and Turku, despite their relatively milder climate due to the Gulf Stream and North Atlantic Drift, also experience freezing conditions. Snowfall becomes a common occurrence, giving the cities a picturesque, winter wonderland appearance.

The sun barely rises in December, especially in the northernmost regions, where the Polar Night is in full effect. The absence of sunlight, however, is frequently offset by the ethereal glow of the Northern Lights, which are a common sight in the Finnish sky during this month.

Precipitation in December, mainly in the form of snowfall, ranges between 60mm (2.36") and 90mm (3.54") across the country. The accumulation of snow creates a thick snow cover, which further contributes to the distinct, wintry landscape.

December also marks the advent of the festive season, with Christmas celebrations occurring under typically white conditions. Despite the extreme cold and limited daylight, the Finnish winter has a unique charm and allure that captivates visitors from all over the world.

As December transitions into January, the severe winter conditions persist, with temperatures frequently dipping below -20°C (-4°F) in the northern regions. Finland's long winter season continues to dominate the landscape and the climate well into the new year.
