Wave data are measured using a Datawell Directional WaveRider Mk III buoy. The buoy was first deployed on 18 December 2006, 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.

The met station was first installed on 01 August 2011. On 29 September 2023, the meterological instrumentation was changed from a Gill Met Pack II to a Gill MaxiMet GMX600.

31/03/2009 Re-deployment of buoy
17/03/2009

Although wave heights and periods are being correctly recorded, the reported wave direction has been suspiciously erratic for several weeks.  Following detailed discussions with Datawell, the buoy will be recovered as soon as possible for investigation.

18/02/2009 A spare buoy has been deployed.  The damaged buoy has been returned to Datawell for assessment.
12/02/2009 The buoy has been recovered.  In addition to the damage near the handles, the HF antenna has been snapped off and the radar reflectors crushed.  The hull appears to be intact, but the impact was sufficiently hard to shock the internal components, to cause the electronics to break free and to shatter some of the batteries.  A spare buoy will be deployed as soon as possible.
10/02/2009 The buoy was run over around 01:00 this morning, and has been badly damaged (one of the handles has come off so clearly the buoy itself has been impacted).  The buoy has been tracked and a boat is en route to recover it.
25/09/2008 Scheduled service and battery change
22/07/2008 The shore station computer has been damaged and will be replaced as soon as possible.
04/01/2008 The buoy has been hit, cut from its mooring and has now beached. It is currently being recovered and will be re-deployed as soon as the weather permits.
17/08/2007 The wave buoy came adrift at around 11:30 today and recovered later that afternoon. The mooring had been sliced through. The buoy will be re-deployed as soon as possible, when the weather conditions improve.
01/02/2007 The buoy has been returned to Datawell for investigation.  A replacement buoy has been deployed.
20/01/2007 The wave buoy has developed a fault, which is currently under investigation by Datawell. Only the GPS position and sea surface temperature are correct.
