About Lowestoft wave buoy

Lowestoft is a Channel Coastal Observatory wave station off the Suffolk coast at Britain's most easterly town. Its North Sea observations provide local context for the harbour approaches, developed seafront and low-lying coastline around Lowestoft and northern Suffolk.

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