Aarhus, Denmark's second-largest city, sits on the east coast of the Jutland peninsula on the Bay of Aarhus, facing the Kattegat sea at approximately 56.16°N, 10.20°E. Its coastal, northerly position gives it a temperate oceanic climate (Köppen Cfb) — mild, cloudy, breezy and changeable, moderated by the surrounding seas — with cool summers, mild winters and rain in every month.
Summer, from June to August, is mild rather than hot, with July and August the warmest months — average highs around 21–22°C and cool nights. Genuinely hot days are rare, though occasional warm spells can push temperatures toward 30°C. It is among the sunniest, driest and most pleasant times of year, with very long northern daylight hours, though showers can arrive at any time.
Winter, from December to February, is cold and grey rather than severe, kept mild for the latitude by the surrounding seas, with January and February the coolest — average highs around 3°C and lows near -1°C. Frost is common, snow falls but rarely lies long, and the season is dominated by short daylight, persistent cloud, drizzle and brisk winds off the Kattegat.
Aarhus receives around 600–650 mm of precipitation a year, spread through every month with a clear autumn maximum — October and November are the wettest — while spring is the driest season; rain is usually light and drizzly rather than heavy. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.
Aarhus's weather is shaped by the seas that surround Jutland, which keep both summer heat and winter cold at bay and bring frequent cloud, drizzle and wind. The city sits slightly in the rain shadow of central Jutland's higher ground, making it a touch drier than the west coast, while the great swing in daylight — from long bright summer evenings to dark winter afternoons — defines the northern year.
