Period Summary

Programmatically generated summary. Hog Says

48 wave-buoy observations were recorded during the day. Typical wave height was 6 ft (10th–90th percentile 5.3–6.6 ft), while mean average of more than one wave period type was 9.2 seconds (10th–90th percentile 8.7–10 seconds). Typical calculated wave power was approximately 12.6 kW/m (10th–90th percentile 9.5–16.4 kW/m), derived from significant wave height and energy period. All 143 checked values passed quality control.
