Period Summary

Hog Says

47 wave-buoy observations were recorded during the day. Typical wave height was 3.4 ft (10th–90th percentile 2.8–3.8 ft), while mean peak wave period was 9.9 seconds (10th–90th percentile 9.1–10.5 seconds). Mean water temperature was 12.5°C (10th–90th percentile 12.1–13.1°C). 1 of 188 checked values (0.5%) were excluded by quality control.

About Perranporth wave buoy

Perranporth is a National Network Datawell Directional WaveRider in about 14 metres of water off Cornwall's exposed north coast. First deployed on 18 December 2006, it records Atlantic swell approaching Perranporth and neighbouring beaches; a separate shore station supplies the local weather context.

Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
