The climate of Alesund
Alesund’s climate is shaped by its coastal location and the warming influence of the Gulf Stream, resulting in relatively mild temperatures for its latitude. Winters (December to February) are chilly but not severe, with average highs of 3–4°C and lows around -1°C. Snowfall is common but rarely heavy, and rain is frequent, making winters damp and overcast. The city receives only 0–1 hour of sunshine per day in winter, and daylight is limited to 5–7 hours, with the shortest days in December.
Summers (June to August) are cool and often cloudy, with average highs of 14–17°C and lows of 9°C. Warm spells can occasionally push temperatures above 20°C, but extreme heat is rare. Rain falls year-round, peaking in September (up to 229 mm), while May is the driest month (about 107 mm). Sunshine is most abundant in May and June, with 6–7 hours per day and daylight stretching to nearly 20 hours at the summer solstice. The famous “white nights” from May to August mean it never gets fully dark, creating a unique atmosphere for late-night strolls and outdoor activities. Winds are moderate but can be brisk, especially during storms, and the sea remains cold year-round, warming to just 14°C in August. Alesund’s weather is famously changeable, so visitors should always be prepared for rain and rapid shifts in conditions.
