Wind in Denmark

The annual mean wind velocity at three coastal locations, Skagen, Hvide Sande and Gedser are between 7.0 to 7.8 m/s (1989-1998 level), and the wind is most frequently from westerly directions, from which about 30-40% of all winds come.

The number of days with severe wind (≥ 10.8 m/s) varies from about 30 in some places inland to above 170 days at Skagen. On average, above storm-force (≥ 24.5 m/s) occurs along the Danish coasts every second to three years. A Danish list of storms has 52 cases with storm force and above in the periode 1891-2016. In December 1999 large parts of Denmark were hit by the worst-ever measured hurricane, and in some places in the North Sea at a oil rig mean wind velocities (average over 10 minutes) of more than 50 m/s (approx. 180 km/h) were recorded, with gusts of about 60 m/s (approx. 216 km/h). During the hurricane “Allan” on 28 October 2013 record-breaking 10 minutes mean winds; 39,5 m/s (approx. 142 km/h) and gusts; 53,5 m/s (approx. 193 km/h) were registered in a coastal area.

Since the mid 1800's and up until today, studies show no general change, only variations, in wind climate.

A windier climate was registered at the beginning and end of the 1900’s, whereas the period from 1930 to early 1960’s has been relatively less windy like the first decade of this millennium. In the last couple of years three hurricanes/strong storms, two in November/December 2013 and one in November 2015, seems to have changed this picture.
