Period Summary

Hog Says

666 wave-buoy observations covered 29 of 31 days (94%). Typical wave height was 2.3 ft (10th–90th percentile 1–4.9 ft), while mean zero-crossing wave period was 4 seconds (10th–90th percentile 3–5 seconds). Typical wind was 12.7 mph (10th–90th percentile 5.8–21.9 mph) and mean water temperature was 13.5°C (10th–90th percentile 12.7–14.5°C). All 3,323 checked values passed quality control.

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.
