The best time to visit Copenhagen is June through August, when average highs reach a comfortable 19.7 °C in June and 20.6 °C in July and August, paired with the year's longest daylight and plenty of sunshine. June is especially pleasant with just 10 rain days, while July climbs to 13. July and August fall in peak season, when school holidays fill Nyhavn and prices rise, so June is the sweet spot for warmth without the biggest crowds. The quiet, dark winter months of December through February stay mild but see as little as 2.2 hours of sunshine a day.

How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.
When to go, and what to expect
Spring (Mar–May)
Great for gardens and long light without summer crowds; late spring is a fine shoulder pick.
Summer (Jun–Aug)
The warmest, brightest window and the best all-round time; choose June to dodge the heaviest crowds.
Autumn (Sep–Nov)
September still feels summery; later autumn suits those who want the city calm and cosy.
Winter (Dec–Feb)
Dark and damp but atmospheric; worth it for Christmas markets and hygge, not for sightseeing weather.

Frequently asked
Is Copenhagen too hot in August?
No. August highs average 20.6 °C with lows around 15 °C, comfortably warm rather than hot, though it sees 12 rain days so pack a light layer and umbrella.
What is the rainiest month?
July and October are the wettest, each with 13 rain days. Even so, summer rain tends to be brief between long sunny spells of up to 12.1 hours a day in July.
Is winter worth visiting?
For atmosphere, yes. Highs sit at 4.1–5.5 °C with as little as 2.2 hours of sunshine in December, so it's dark and damp, but the Christmas markets and cosy interiors make it rewarding if you skip beach-weather expectations.
