Traveller notes on Aarhus in August
Other months in Aarhus

Posters generally rate December as cold and dark but manageable with proper winter layers for a visit to Aarhus.
June in Aarhus brings seventeen and a half hours of daylight and days around 20°C, which the forum is careful to say can also run a good deal lower. Their standing note about Denmark holds here: you will still want a sweater, because the wind off the water is prickly cold even in summer. Rain comes in showers rather than all day — Danish weather is unpredictable, but it is rarely a write-off. The sea reaches about 17°C. Aarhus works well as a base for excursions and is easy from Copenhagen, by frequent train or a cheaper bus.
