Weather in Copenhagen in October

Copenhagen in October suits a city break if you are happy with cool weather and flexible outdoor plans, but it is not a good choice for warmth. Average daytime highs are 11.8°C, nights fall to 7.8°C, and about 12 days have rain.

October is not the strongest month here: cool days and frequent rain. The best months for Copenhagen on our scoring are July, August, June.

Cool days, with a sharper chill after dark

Pack for a jacket most days rather than hoping for shirtsleeve weather. The warmer end of October can reach 15.6°C or more, which may feel comfortable for walking, but that is not the temperature to build your packing around. At the colder end, nights can fall to 3.3°C or below, so a warm layer matters if you plan to stay out after dark. A jumper beneath a weatherproof outer layer gives you more flexibility than relying on a light jacket alone. This is a better month for travellers who enjoy walking in cool conditions than for anyone wanting to sit outdoors for long stretches.

Plan around rain and limited sunshine

Rain is a meaningful part of the October trade-off, so keep outdoor plans movable rather than assigning everything to a fixed day. About 3.1 hours of sunshine within 10.1 hours of daylight means you should not expect bright conditions throughout the day, even when it stays dry. Put the outdoor parts of your break into the available daylight and keep indoor time flexible. Waterproof footwear and a rainproof jacket are sensible choices, especially if you intend to do much of your exploring on foot. October can still work for a weather-tolerant traveller, but it is less suitable if grey skies or wet spells would spoil the trip.
