Climate

Copenhagen is in the oceanic climate zone (Köppen: Cfb). Its weather is subject to low-pressure systems from the Atlantic which result in unstable conditions throughout the year. Apart from slightly higher rainfall from July to September, precipitation is moderate. While snowfall occurs mainly from late December to early March, there can also be rain, with average temperatures around the freezing point.

June is the sunniest month of the year with an average of about eight hours of sunshine a day. July is the warmest month with an average daytime high of 21 °C. By contrast, the average hours of sunshine are less than two per day in November and only one and a half per day from December to February. In the spring, it gets warmer again with four to six hours of sunshine per day from March to May. February is the driest month of the year. Exceptional weather conditions can bring as much as 50 cm of snow to Copenhagen in a 24-hour period during the winter months while summer temperatures have been known to rise to heights of 33 °C (91 °F).

Because of Copenhagen's northern latitude, the number of daylight hours varies considerably between summer and winter. On the summer solstice, the sun rises at 04:26 and sets at 21:58, providing 17 hours 32 minutes of daylight. On the winter solstice, it rises at 08:37 and sets at 15:39 with 7 hours and 1 minute of daylight. There is therefore a difference of 10 hours and 31 minutes in the length of days and nights between the summer and winter solstices.
