Period Summary

Hog Says

1,488 wave-buoy observations covered all 31 days. Typical wave height was 2.8 ft (10th–90th percentile 0.9–6.1 ft), while mean average wave period was 4 seconds (10th–90th percentile 2.9–5.1 seconds). All 4,464 checked values passed quality control. Across 15 comparable years, mean wave height was below the same-month mean of 3.6 ft and mean wave period was below 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.
