Period Summary

Programmatically generated summary. Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 3.4 ft (10th–90th percentile 2.6–6.2 ft), while mean peak wave period was 9.3 seconds (10th–90th percentile 8.4–10.2 seconds). Typical calculated wave power was approximately 4.2 kW/m (10th–90th percentile 2.7–12.3 kW/m), derived from significant wave height and energy period. All 144 checked values passed quality control.
