Period Summary
Programmatically generated summary. Hog Says48 wave-buoy observations were recorded during the day. Typical wave height was 3.6 ft (10th–90th percentile 2.9–4.3 ft), while mean peak wave period was 8.8 seconds (10th–90th percentile 7–9.6 seconds). Typical calculated wave power was approximately 4.7 kW/m (10th–90th percentile 3–5.5 kW/m), derived from significant wave height and energy period. All 144 checked values passed quality control.

About Saint-Jean-de-Luz wave buoy
Saint-Jean-de-Luz is a CANDHIS directional buoy on the French Basque coast near the Spanish border. Maintained through the Cerema-coordinated national observatory and local partners, it provides offshore context for a naturally embayed and partly protected coast exposed to southern Bay of Biscay swell.
Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
