Period Summary

Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 8 ft (10th–90th percentile 5.3–9.6 ft), while mean peak wave period was 13.8 seconds (10th–90th percentile 13.4–14.1 seconds). Typical calculated wave power was approximately 35.5 kW/m (10th–90th percentile 14–51.6 kW/m), derived from significant wave height and energy period. All 144 checked values passed quality control.

About Les Pierres Noires wave buoy

Les Pierres Noires is a CANDHIS directional buoy west of Brittany, maintained through the French national sea-state observatory and its scientific and maritime partners. Its position near the offshore reef and lighthouse represents fully exposed Atlantic conditions approaching the Iroise Sea and western Brittany.

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