Wave buoy location
||50° 21.19' N 005° 10.48' W|
|Approximate water depth||14 m CD|
|Approximate spring tidal range||6.1 m|
|Storm alert threshold||5.33 m|
|Met station location||50° 20.77' N 005° 09.71' W|
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.
The shore station is kindly hosted by Perranporth Youth Hostel.
|24/02/2015||A problem with the phone line at the shore station has prevented data being uploaded to the website. BT will fix ASAP.|
|29/10/2014||Buoy swapped out today.|
|12/03/2014||Buoy has now been redeployed.|
|09/02/2014||The buoy has been recovered; the efforts of local beach staff and users to assist with the recovery are much appreciated.|
|08/02/2014||The buoy has come ashore and appears to be badly damaged; rescue attempts are underway.|
|16/05/2013||Buoy came adrift. Possibly entangled with fishing vessel. Now towed to Newquay harbour.|
|09/03/2013||Buoy swapped out|
|12/07/2011||Data not coming through to the website, BT alerted|
|12/09/2010||Data from Plymouth University's met. station at Perranporth have been added to the website, by kind permission of Dr M. A. Davidson|
|08/07/2009||The service visit has indicated that the majority of equipment at shore station needs replacing, BT engineer on route to fix the phone line|
|03/07/2009||The shore station computer and ancillary equipment were destroyed by a lightning strike last night.|
|31/03/2009||Re-deployment of buoy|
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.|
