Period Summary

Programmatically generated summary. Hog Says

24 wave-buoy observations were recorded during the day. Typical wave height was 2.3 ft (10th–90th percentile 1.3–5.5 ft), while mean average wave period was 5.3 seconds (10th–90th percentile 4.5–6 seconds). Typical wind was 26 mph (10th–90th percentile 18.4–34.5 mph) and mean water temperature was 20.5°C (10th–90th percentile 20.5–20.6°C). All 120 checked values passed quality control.

About F3 wave buoy

F3 Light Vessel (WMO 62170) is a UK Met Office station in the southern North Sea, east of the Dover Strait. It provides an offshore reference for forecasts and shipping in the shallow waters between southeast England, Belgium and the Netherlands, beyond the immediate shelter or distortion of the coast.

Its current data source reports wave height, wave period, wind conditions 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.

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.
