Period Summary
Programmatically generated summary. Hog Says24 wave-buoy observations were recorded during the day. Typical wave height was 2.5 ft (10th–90th percentile 1.9–4 ft), while mean peak wave period was 9 seconds (10th–90th percentile 6.7–14.8 seconds). Typical wind was 10.1 mph (10th–90th percentile 6.4–15.1 mph) and mean water temperature was 8.9°C (10th–90th percentile 8.8–8.9°C). 1 of 144 checked values (0.7%) were excluded by 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.
