Period Summary
Programmatically generated summary. Hog Says
718 wave-buoy observations covered all 30 days. Typical wave height was 2.3 ft (10th–90th percentile 0.7–4.9 ft), while mean reported wave period; measurement type unavailable was 6 seconds (10th–90th percentile 5–7 seconds). Typical wind was 21.9 mph (10th–90th percentile 8.1–34.5 mph) and mean water temperature was 18°C (10th–90th percentile 17.2–18.9°C). All 3,590 checked values passed quality control. Across 2 comparable years, mean wave height was above the same-month mean of 1.8 ft and mean wave period was above the same-month mean of 5.7 seconds.
