Period Summary

Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 6.5 ft (10th–90th percentile 5.9–7.8 ft), while mean peak wave period was 14.1 seconds (10th–90th percentile 13.1–16.4 seconds). Typical calculated wave power was approximately 24 kW/m (10th–90th percentile 19.3–39.9 kW/m), derived from significant wave height and energy period. All 144 checked values passed quality control.

About Cap Ferret wave buoy

Cap Ferret is a long-running CANDHIS directional buoy off the Aquitaine coast, operated within France's national in-situ sea-state observatory. It provides an offshore reference for the energetic Bay of Biscay swell approaching the Arcachon inlet and the long, sandy and erosion-prone Landes coastline.

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