Period Summary

Hog Says

1,079 wave-buoy observations covered 23 of 31 days (74%). Typical wave height was 4.2 ft (10th–90th percentile 2.3–8.4 ft), while mean average of more than one wave period type was 4.7 seconds (10th–90th percentile 3.9–5.7 seconds). All 3,235 checked values passed quality control. Across 10 comparable years, mean wave height was above the same-month mean of 3.3 ft and mean wave period was above the same-month mean of 4.4 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.
