Denmark has a temperate climate, the mildness of which is largely conditioned by the generally westerly winds and by the fact that the country is virtually encircled by water.
There is little fluctuation between day and night temperatures, but sudden changes in wind direction cause considerable day-to-day temperature changes. The mean temperature in February, the coldest month, is 0°C (32°F), and in July, the warmest, 17°C (63°F). Rain falls fairly evenly throughout the year, the annual average amounting to approximately 61 cm (24 in).
Because of Denmark’s northern location in Europe, the length of the day with sunlight varies greatly. There are short days during the winter with sunrise coming around 8 am and sunset 3:30 pm, as well as beautifully long summer days with sunrise at 3:30 am and late sunsets at 10 pm.
The shortest and longest days of the year have traditionally been celebrated. The celebration for the shortest day corresponds roughly with Christmas
The weather in Copenhagen is mild through all the four seasons. Summers bring temperatures averaging around 68°F (20°C), while in mid-winter temperatures hover just above or below zero. Rainfall is moderate too, but spread throughout the year, so showers are possible in any season.
