Weather in Copenhagen

Weather - Copenhagen

Copenhagen has a temperate maritime climate: relatively mild winters, cool summers and frequent changeable weather driven by the sea and Atlantic winds. Expect breezy, overcast days through much of the year, with the best weather for sightseeing and outdoor cafes from late spring to early autumn. If you're booking flights, aim for May–June or September for pleasant temperatures, longer daylight and fewer tourists; July–August bring the warmest sea temperatures for a chilly swim.

Weather - Copenhagen - January

January is one of the coldest months: daytime highs around 3 °C and lows near −1 °C. Short daylight (about 8 hours) and regular precipitation — often as sleet or snow — make it brisk and windy. Good for winter city breaks if you enjoy museums, cozy cafés and Christmas-season atmospheres, but pack warm layers and windproof outerwear.

Weather - Copenhagen - February

February stays chilly with average highs near 4 °C and lows around −1 °C, and slightly fewer precipitation days than January. Days lengthen to about 10 hours, but snow and strong winds remain possible. It’s a quiet month for lower-priced flights and off-season culture visits.

Weather - Copenhagen - March

March brings a gradual thaw — highs around 6 °C and lows close to freezing. Expect variable conditions: some sunny stretches mixed with rainy or wintry showers. With increasing daylight (~12 hours), March is a good shoulder-month choice for cheaper fares and the first signs of spring.

Weather - Copenhagen - April

April feels fresher and more spring-like: average highs near 11 °C and lows about 3 °C, with up to 14 hours of daylight. Showers are common but so are clearer, crisp days — ideal for strolling the canals and parks as the city wakes up for the season.

Weather - Copenhagen - May

May is a pleasant month for visiting: daytime temperatures average around 16 °C with cool nights near 7 °C. Daylight stretches to about 16 hours and sunshine increases, although occasional rain can occur. It’s a sweet spot for outdoor dining, cycling the city and catching earlier ferry connections.

Weather - Copenhagen - June

June offers mild, comfortable weather — highs around 19 °C and lows about 11 °C — and long summer days (roughly 17 hours). Rainfall increases at times, but warm daytime temperatures and pleasant light make it excellent for sightseeing, harbor walks and early beach outings as sea temperatures climb.

Weather - Copenhagen - July

July is the warmest month with average highs near 21 °C and nighttime lows around 13 °C. Despite being breezy and with regular showers, July is the best time for swimming (sea temperatures about 17 °C), outdoor events and peak tourist activity — book flights and hotels early.

Weather - Copenhagen - August

August is similar to July: warm days around 21 °C, mild nights and sea temperatures suitable for a cool dip. Expect some rainy spells, but also long daylight and lively outdoor culture. It’s a popular month, combining the warmest weather with Copenhagen’s summer festivals.

Weather - Copenhagen - September

September cools to average highs near 18 °C and lows about 10 °C, with decreasing daylight and fewer crowds. The sea remains relatively mild (~15 °C) and the weather is often pleasant for city walks and early autumn escapes — a practical choice for lower fares while still enjoying comfortable temperatures.

Weather - Copenhagen - October

October turns noticeably cooler: highs around 12 °C and lows near 7 °C, with more frequent rain and blustery conditions. Shorter days and autumn colors make it atmospheric for cultural visits, although you’ll want waterproofs and layers for variable conditions.

Weather - Copenhagen - November

November is chilly and often overcast, with average highs of about 7 °C and lows near 4 °C, and limited daylight (~8 hours). It’s a true off-season month — ideal for bargain flights and indoor attractions, but expect damp, grey weather and occasional wintry showers.

Weather - Copenhagen - December

December brings winter conditions: daytime highs around 4 °C, nights close to 1 °C, and limited daylight (~7 hours). Snow is possible and the city turns festive — great for holiday markets and cozy urban experiences, but dress warmly and be ready for windy, wet days.
