Wave data are measured using a Datawell Directional Waverider Mk III buoy. The buoy was deployed on the 10th September 2009, at which time the magnetic declination at the site was 2.8° west, changing by 0.15° east per year. Wave direction is reported following the nautical convention, meaning that the direction is where the waves come from, measured clockwise from magnetic north.

A Vaisala WXT536 meteorological station was installed at the Beach Office on Marine Paride in Weston-Super-Mare on 17 June 2021.
