Period Summary

Hog Says

1,487 wave-buoy observations covered all 31 days. Typical wave height was 2.6 ft (10th–90th percentile 1.1–5.8 ft), while mean average of more than one wave period type was 6.3 seconds (10th–90th percentile 4.4–8 seconds). Mean water temperature was 6.4°C (10th–90th percentile 5.6–7.6°C). 5 of 5,908 checked values (0.1%) were excluded by quality control. Across 1 comparable year, mean wave height was above the same-month mean of 2.1 ft and mean wave period was above the same-month mean of 5.2 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.
