Period Summary
Programmatically generated summary. Hog Says
737 wave-buoy observations covered all 31 days. Typical wave height was 8.9 ft (10th–90th percentile 5.9–17.1 ft), while mean reported wave period; measurement type unavailable was 7.3 seconds (10th–90th percentile 6–9 seconds). Typical wind was 17.3 mph (10th–90th percentile 9.2–30 mph) and mean water temperature was 10.7°C (10th–90th percentile 10.6–11°C). All 3,685 checked values passed quality control. Across 3 comparable years, mean wave height was above the same-month mean of 8.6 ft and mean wave period was above the same-month mean of 6.5 seconds.

About K4 wave buoy
K4 (WMO 62105) is a UK Met Office buoy in the North Atlantic northwest of Ireland. Its remote position samples weather and sea conditions moving towards northern UK and Irish waters. The international station feed can include wind, pressure, temperature and wave observations, although the reported parameters vary with sensor availability.
Metrics are rows; days run left to right.
