K1
- offshoreAbout
K1 (WMO 62029) is a UK Met Office buoy in the Atlantic approaches, southwest of Ireland. Its exposed position provides an early view of Atlantic weather and sea conditions moving towards Ireland and western UK waters. The international station feed can include wind, pressure, air and sea temperature, and wave observations when the relevant sensors are reporting.
St Mary's Sound
- inshoreAbout
St Mary's Sound station lies between the islands of St Mary's and St Agnes in the Isles of Scilly. The National Network first deployed its Datawell Directional WaveRider in May 2014 to measure the exposed nearshore wave climate around the archipelago. The station reports wave height, period and direction together with sea temperature.
Sevenstones
- offshoreAbout
Sevenstones Lightship (WMO 62107) is a UK Met Office station west of Land's End in the Western Approaches. It is well placed to show Atlantic swell before it reaches Cornwall and the western English Channel. The station feed includes wave height and period, pressure, air and sea temperature, and other marine observations when available.
Penzance
- inshoreAbout
Penzance is a Datawell Directional WaveRider station in Mount's Bay off west Cornwall. First deployed by the National Network in April 2007, it records the comparatively sheltered wave climate on the bay's western side. Available observations include wave height, period and direction, sea temperature and calculated wave power.
Porthleven
- inshoreAbout
Porthleven is a Datawell Directional WaveRider station off Cornwall's exposed south coast. First deployed by the National Network in October 2011, it measures waves approaching the Porthleven frontage from the western English Channel. Observations include wave height, period and direction, sea temperature and calculated wave power.
Perranporth
- inshoreAbout
Perranporth is a Datawell Directional WaveRider station in about 14 metres of water off Cornwall's exposed north coast. First deployed in December 2006, it measures Atlantic swell approaching Perranporth and the surrounding beaches. Observations include wave height, period and direction, sea temperature and calculated wave power; a nearby shore station supplies separate weather data.
Port Isaac
- inshoreAbout
Port Isaac is a National Network step-gauge station off north Cornwall, first deployed in July 2010. Unlike the directional WaveRider buoys elsewhere in the network, this installation measures the local sea surface using a fixed gauge. Its record helps describe wave and water-level conditions on the exposed coast around Port Isaac.
Looe Bay
- inshoreAbout
Looe Bay is a Datawell Directional WaveRider station off southeast Cornwall. First deployed in June 2009, it measures the wave climate entering the bay and the approaches to Looe. Observations include wave height, period and direction, sea temperature and calculated wave power; a nearby meteorological station provides separate weather measurements.
Bideford Bay
- inshoreAbout
Bideford Bay is a Datawell Directional WaveRider station in about 11 metres of water off north Devon. Deployed in June 2009, it records Atlantic waves entering the broad bay between Hartland Point and Morte Point. The station reports wave height, period and direction, sea temperature and calculated wave power, with its shore receiver hosted by RNLI Appledore.
Minehead
- inshoreAbout
Minehead is a Datawell Directional WaveRider station in the Bristol Channel off the Somerset coast. First deployed in December 2006, it records the short-period and locally generated waves that reach the Minehead frontage. Available observations include wave height, period and direction, sea temperature and calculated wave power.
Weston Bay
- inshoreAbout
Weston Bay is a Datawell Directional WaveRider station in the upper Bristol Channel off Weston-super-Mare. Deployed in September 2009, it records waves in a shallow, strongly tidal part of the estuary. Available observations include wave height, period and direction, sea temperature and calculated wave power.
