Period Summary

Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 17.5 ft (10th–90th percentile 10.5–23.9 ft), while mean peak wave period was 14.9 seconds (10th–90th percentile 13.7–15.8 seconds). Typical calculated wave power was approximately 166.7 kW/m (10th–90th percentile 61.5–322.7 kW/m), derived from significant wave height and energy period. 1 of 144 checked values (0.7%) were excluded by quality control.

About Île de Batz wave buoy

Île de Batz is a CANDHIS directional buoy off northern Brittany, within the French national sea-state observatory coordinated by Cerema. The station sits at the western entrance to the English Channel, where Atlantic swell rounds Brittany towards the exposed Finistère and Channel coasts.

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