Temperature in Denmark

Denmark has a relatively warm climate compared to other geographic areas at the same latitude. As comparison, it is much colder in both the southern part of Hudson Bay in Canada and Siberia in Russia although both areas are at the same latitude as Denmark. The relatively warm climate is due to the warm North Atlantic Drift which originates in the tropical seas off the U.S. east coast.

The annual mean temperature varies from year to year, from below 6ºC to 10ºC, with an average of 8.3ºC (1981-2010 level; 8.9ºC (2006-2015 level). The coldest year so far was 1879, with a mean temperature of 5.9ºC, while the hottest recorded year was 2014, with 10.0ºC. Since 1988, the majority  of years has been hotter than average 1981-2010, and the temperature has shown a sharply rising trend from the 1990s. Since 1870, the temperature in Denmark has risen by about 1.5ºC, but the ten hottest years have occurred from the 1930s to present. The present temperature level is the highest in the time series and the period 2001-2010 was the warmest decade since records began. 

The temperature in January and February averages around 1°C (1981-2010 level); around 1.3°C (2006-2015 level) but can vary greatly from more than 15°C to below -31°C. The average temperature in July and August is around 16.5°C (1981-2010); around 17°C (2006-2015), but again can vary from -2°C to more than 36°C.

Annual average temperature since 1873 for Denmark; anomaly relative to 1981-2010. The values are calculated national average based on a number of selected stations. As the global temperature shows the temperatures for Denmark shows a clear increase in the annual mean temperature in the last decades. Data is published in DMI's report series.
