Period Summary
Programmatically generated summary. Hog Says
717 wave-buoy observations covered all 30 days. Typical wave height was 3 ft (10th–90th percentile 1.3–7.9 ft), while mean reported wave period; measurement type unavailable was 6.9 seconds (10th–90th percentile 5–8 seconds). Typical wind was 20.8 mph (10th–90th percentile 11.4–32.2 mph) and mean water temperature was 16.7°C (10th–90th percentile 16.5–17°C). All 3,585 checked values passed quality control. Across 9 comparable years, mean wave height was above the same-month mean of 3.3 ft and mean wave period was below the same-month mean of 7.5 seconds.

About Ch. Lightship wave buoy
Channel Lightship (WMO 62103) is a UK Met Office station in the central English Channel. Its offshore position provides marine observations away from the immediate influence of the coast and is useful for tracking conditions along this major shipping route. The feed can include wind, pressure, air and sea temperature, visibility and wave observations when available.
Metrics are rows; days run left to right.
