Period Summary

Hog Says

1,486 wave-buoy observations covered all 31 days. Typical wave height was 2 ft (10th–90th percentile 0.9–3.6 ft), while mean average of more than one wave period type was 5.1 seconds (10th–90th percentile 3.5–6.7 seconds). Mean water temperature was 7.1°C (10th–90th percentile 6.2–8.1°C). All 5,937 checked values passed quality control. Across 4 comparable years, mean wave height was below the same-month mean of 2.7 ft and mean wave period was below the same-month mean of 6.8 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.
