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.
