CoolWeather in Copenhagen in April
Copenhagen in April is a reasonable choice for a city break if you are happy with cool weather and flexible outdoor plans, but not if you want warmth. Average daytime highs are around 11°C, nights fall to around 4°C, and about 10 days have rain. Pack for chilly evenings and wet spells rather than relying on spring sunshine. The appeal is having time outdoors when conditions suit, without expecting every day to feel comfortable in a light jacket.

Nights average 3.8°C; one night in ten drops to 0.1°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest April day here reached 23.0°C (1993-04-28) and the coldest night -8.0°C (2013-04-01).

Dress for cool days and colder evenings
The main catch is that a pleasant afternoon does not mean a mild evening. A daytime high around 11°C calls for layers, while the average night low around 4°C makes a warm outer layer useful if you plan to stay out late. The warmest days can reach 15.5°C or more, so a lighter layer underneath gives you flexibility. At the colder end, nights can fall to around freezing or below. Treat a warm afternoon as a bonus rather than the basis for your packing. This suits travellers who enjoy being outdoors in a coat more than those hoping to spend long stretches sitting outside.
Plenty of daylight, but keep wet-weather plans
April brings about 13.9 hours of daylight, giving you room to shift outdoor plans around the weather rather than squeezing them into a short day. Sunshine averages about 5.7 hours daily, though, so long daylight should not be mistaken for reliably clear skies. With about 10 rainy days, a waterproof jacket and shoes that cope with wet pavements are sensible choices. Keep indoor options available and avoid making the whole trip depend on dry conditions. The balance works best if you are comfortable adjusting plans: make use of brighter weather when it arrives, but bring enough warm clothing that cloudier days do not leave you stuck indoors.
