Period Summary

Hog Says

1,488 wave-buoy observations covered all 31 days. Typical wave height was 2 ft (10th–90th percentile 1.1–3.7 ft), while mean peak wave period was 5.1 seconds (10th–90th percentile 3.6–6.5 seconds). Mean water temperature was 18.3°C (10th–90th percentile 17.7–18.8°C). 1 of 5,952 checked values (0%) were excluded by quality control. Across 1 comparable year, mean wave height was above the same-month mean of 1.7 ft and mean wave period was above the same-month mean of 4.9 seconds.

About Lowestoft wave buoy

Lowestoft is a Channel Coastal Observatory wave station off the Suffolk coast at Britain's most easterly town. Its North Sea observations provide local context for the harbour approaches, developed seafront and low-lying coastline around Lowestoft and northern Suffolk.

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