Period Summary
Programmatically generated summary. Hog Says48 wave-buoy observations were recorded during the day. Typical wave height was 3.4 ft (10th–90th percentile 2.8–5.4 ft), while mean peak wave period was 9 seconds (10th–90th percentile 5–11 seconds). Typical calculated wave power was approximately 3.8 kW/m (10th–90th percentile 3–8 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.
