Wave data are measured using a Datawell Directional WaveRider Mk III buoy. The buoy was first deployed on 06 April 2007, at which time the magnetic declination at the site was 3.9° 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 Penzance Harbour Office on 8 December 2020.
