Period Summary

Hog Says

1,489 wave-buoy observations covered all 31 days. Typical wave height was 1.4 ft (10th–90th percentile 0.8–3.1 ft), while mean average of more than one wave period type was 7.6 seconds (10th–90th percentile 3.6–13.3 seconds). Mean water temperature was 15°C (10th–90th percentile 13.6–17.1°C). 17 of 5,701 checked values (0.3%) were excluded by quality control. Across 6 comparable years, mean wave height was below the same-month mean of 2.7 ft and mean wave period was above the same-month mean of 7 seconds.

About Bracklesham Bay wave buoy

Bracklesham Bay is a Channel Coastal Observatory National Network wave station off the West Sussex coast. Its nearshore position records conditions entering the broad bay between Selsey and Hayling Island, supporting coastal management along an exposed beach frontage west of Chichester Harbour.

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