Period Summary

Hog Says

739 wave-buoy observations covered all 31 days. Typical wave height was 3.1 ft (10th–90th percentile 1–7.8 ft), while mean peak wave period was 5.5 seconds (10th–90th percentile 3.4–8 seconds). Typical wind was 14.7 mph (10th–90th percentile 6.2–27.5 mph) and mean water temperature was 8.6°C (10th–90th percentile 8.3–8.9°C). 1 of 4,434 checked values (0%) were excluded by quality control. Across 5 comparable years, mean wave height was above the same-month mean of 3.2 ft and mean wave period was above the same-month mean of 5.2 seconds.

About M2 wave buoy

M2 (WMO 62091) is part of the Irish Marine Data Buoy Observation Network, managed by the Marine Institute in collaboration with Met Éireann. Moored in the Irish Sea east of Ireland, it provides open-water context for the busy, relatively enclosed waters between the Irish and British coasts.

Its current data source reports wave height, wave period, wave direction, directional spread, wind conditions and sea temperature.
