Period Summary

Programmatically generated summary. Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 4 ft (10th–90th percentile 3.7–4.4 ft), while mean peak wave period was 6.5 seconds (10th–90th percentile 6.3–7 seconds). Typical calculated wave power was approximately 4.4 kW/m (10th–90th percentile 3.8–5 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.
