Period Summary

Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 12.3 ft (10th–90th percentile 10.8–16.4 ft), while mean peak wave period was 13.7 seconds (10th–90th percentile 12.9–14.4 seconds). Typical calculated wave power was approximately 81.5 kW/m (10th–90th percentile 60.3–147.8 kW/m), derived from significant wave height and energy period. All 144 checked values passed quality control.

About Belle-Île wave buoy

Belle-Île is a CANDHIS directional buoy south of Brittany, maintained through the Cerema-coordinated sea-state observatory and research partners. Its open Atlantic position represents conditions approaching Belle-Île and the sheltered-to-exposed transition along the Morbihan coast.

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