Wind in Denmark

Annual average wind speed across Denmark is 5.8 m/s. Prevailing wind is west from where approx. 25% of all winds originate. Naturally, wind varies widely from coastal to inland regions.

Number of days with strong winds (10.8 - 13.8 m/s) ranges from approx. 30 in certain inland areas to almost 170 at the northernmost point of Jutland in Skagen.

Storms (over 24.5 m/s) are most frequent along coastal areas during winter and occur every 3 to 4 years on average. In December 1999, a record-breaking hurricane hit large parts of Denmark. In some areas, mean wind speeds (10-minute average wind speed) of more than 40 m/s (nearly 150 km/h) with gusts up to 50 m/s (approx. 185 km/h) were registered. 

During the hurricane “Allan” on 28 October 2013 new 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.

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.
