Period Summary

Hog Says

111 wave-buoy observations were recorded during the day. Typical wave height was 3.8 ft (10th–90th percentile 3.3–4.1 ft), while mean average of more than one wave period type was 5.8 seconds (10th–90th percentile 4.8–6.7 seconds). Typical calculated wave power was approximately 3.4 kW/m (10th–90th percentile 2.4–4 kW/m), derived from significant wave height and energy period. All 311 checked values passed quality control.

About Schiermonnikoog Noord wave buoy

Schiermonnikoog Noord is a Rijkswaterstaat station in the North Sea north of the Dutch Wadden Islands. It supplies offshore context for the highly dynamic island coast and tidal-inlet system at the boundary between the open North Sea and the Wadden Sea.

Its current data source reports wave height, wave period and wave direction. SurfHog calculates wave power when wave height and energy period are available.
