Period Summary

Hog Says

576 wave-buoy observations covered 18 of 31 days (58%). Typical wave height was 3.6 ft (10th–90th percentile 1.7–9 ft), while mean average of more than one wave period type was 4.9 seconds (10th–90th percentile 3.6–6.1 seconds). 3 of 1,721 checked values (0.2%) were excluded by quality control. Across 8 comparable years, mean wave height was the same as the same-month mean of 4.5 ft and mean wave period was above the same-month mean of 4.7 seconds.

About Fjaltring wave buoy

Fjaltring is a Danish Coastal Authority directional buoy off the exposed central west coast of Jutland. The authority has maintained a continuous wave-measurement programme here since 1980, creating a key reference for Denmark's most erosion-prone coast and the long-running Lodbjerg–Nymindegab protection works.

Its current data source reports wave height, wave period and wave direction.
