Climate Characteristics of Sundsvall

Where North Meets South

Sundsvall enjoys a unique geographical position, granting it a humid-maritime climate with continental influences. Surrounded by two prominent hills (Norra and Södra Stadsberget), the historic "Stone City" is protected from harsh winds. Unlike the south, winters are stable and snowy, yet much milder than in the Arctic north.

A Winter of Adventure

Winter in Sundsvall is stable and accessible, with temperatures typically between -2°C and -6°C (21-28°F). The snow stays for months, making the surrounding hills popular spots for both alpine and cross-country skiing, just minutes from the city center.

Green, Luminous Summer

With its mid-northern location, Sundsvall enjoys very long summer days. Temperatures are exceptionally pleasant, around 20-23°C (68-73°F). This is when the city truly wakes up, with cafes lining the pedestrian streets and residents heading to nearby Baltic beaches.

Weather in Sundsvall by Month
