Period Summary

Programmatically generated summary. Hog Says

608 wave-buoy observations covered 13 of 30 days (43%). Typical wave height was 1 ft (10th–90th percentile 0.6–1.8 ft), while mean average of more than one wave period type was 4.5 seconds (10th–90th percentile 2.8–7.1 seconds). Mean water temperature was 15.2°C (10th–90th percentile 13.9–16.5°C). 1 of 2,412 checked values (0%) were excluded by quality control.

About Spurn Point wave buoy

Spurn Point is a Channel Coastal Observatory wave station off the narrow spit at the mouth of the Humber. It records North Sea conditions beside a highly mobile coastal landform and provides context for the estuary entrance, nearby shipping routes and the exposed southern Holderness coast.

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

Wave metric colour key

Colours move through the scale as each number increases. They do not by themselves mean that conditions are good, safe or suitable for you.

Wave & swell height0–40+ ft
Wave & swell period0–22+ s
Wind speed0–75 mph

The displayed numbers remain the source of truth; colour is an additional visual cue.

What does buoy wave power mean?

kW/m means kilowatts of wave power per metre of wave crest. It describes the rate at which the observed sea state carries energy past the buoy.

Unlike the shore-directed forecast value, buoy wave power is the total power at the observation point. It is not projected towards a particular beach and does not predict breaking wave height.

In deep water, wave power can be calculated with:

P is approximately 0.49 times significant wave height squared times wave energy period.

P is power in kW/m, Hs is significant wave height in metres, and Te is wave energy period in seconds.

  • Provider-reported power is used when available.
  • Otherwise, a value is calculated only when both significant height and a genuine energy period are available. The ≈ symbol marks calculated values.
  • A dash is shown instead of substituting peak, Tm02, zero-crossing or other period measurements.
  • Daily and monthly figures use the mean of hourly-normalized observation power values; they are not calculated from mean height and period.

Wave direction, spectrum, water depth and local bathymetry still matter. Wave power is best read alongside height, period and direction rather than as a standalone surf-quality score.
