Period Summary

Hog Says

1,488 wave-buoy observations covered all 31 days. Typical wave height was 2.5 ft (10th–90th percentile 1.1–5.7 ft), while mean average of more than one wave period type was 7.2 seconds (10th–90th percentile 3.2–11.1 seconds). Mean water temperature was 11.8°C (10th–90th percentile 10.8–12.6°C). 3 of 5,799 checked values (0.1%) were excluded by quality control. Across 2 comparable years, mean wave height was below the same-month mean of 3.1 ft and mean wave period was below the same-month mean of 7.5 seconds.

About Hornsea wave buoy

Hornsea is a Channel Coastal Observatory wave station off the rapidly eroding Holderness coast of East Yorkshire. Its North Sea record provides local wave context for Hornsea's defended frontage and the adjacent soft-cliff coastline, where storms drive substantial shoreline change.

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