Period Summary

Hog Says

1,482 wave-buoy observations covered all 31 days. Typical wave height was 3 ft (10th–90th percentile 1.7–4.7 ft), while mean average of more than one wave period type was 5.9 seconds (10th–90th percentile 4.1–8 seconds). Mean water temperature was 6.6°C (10th–90th percentile 6–7.5°C). 16 of 5,898 checked values (0.3%) were excluded by quality control. Across 6 comparable years, mean wave height was above the same-month mean of 2.9 ft and mean wave period was the same as the same-month mean of 5.9 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.
