Period Summary

Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 2.2 ft (10th–90th percentile 2–2.5 ft), while mean peak wave period was 12.6 seconds (10th–90th percentile 11.8–14.2 seconds). Typical calculated wave power was approximately 2 kW/m (10th–90th percentile 1.6–2.5 kW/m), derived from significant wave height and energy period. All 144 checked values passed quality control.

About Plateau du Four wave buoy

Plateau du Four is a CANDHIS station associated with the SEM-REV offshore test site off Loire-Atlantique. Located near a shallow offshore bank west of Le Croisic, it supplies environmental context for marine-energy research and for an exposed sector between the Loire estuary and southern Brittany.

Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
