Period Summary

Hog Says

1,261 wave-buoy observations covered all 30 days. Typical wave height was 2 ft (10th–90th percentile 1–4.8 ft), while mean peak wave period was 5.8 seconds (10th–90th percentile 4.3–7.4 seconds). Mean water temperature was 9.5°C (10th–90th percentile 8.4–10.3°C). All 5,044 checked values passed quality control. Across 4 comparable years, mean wave height was above the same-month mean of 2.4 ft and mean wave period was below the same-month mean of 7 seconds.

About Happisburgh wave buoy

Happisburgh is a Channel Coastal Observatory wave station off the northeast Norfolk coast. It supplies a nearshore North Sea record for one of England's most rapidly changing soft-cliff frontages, where communities, beaches and coastal defences are exposed to frequent erosion.

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