Period Summary

Hog Says

1,440 wave-buoy observations covered all 30 days. Typical wave height was 2 ft (10th–90th percentile 0.9–3.8 ft), while mean average of more than one wave period type was 6.8 seconds (10th–90th percentile 4–10 seconds). Mean water temperature was 14.4°C (10th–90th percentile 13.8–15.1°C). 2 of 5,730 checked values (0%) were excluded by quality control. Across 9 comparable years, mean wave height was below the same-month mean of 2.4 ft and mean wave period was below the same-month mean of 7.5 seconds.

About Chesil wave buoy

Chesil is a Channel Coastal Observatory National Network wave station off Dorset's exposed Jurassic Coast. It records waves approaching Chesil Beach and the western side of Portland, providing a nearshore reference for the long shingle barrier and the communities and infrastructure behind it.

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