Period Summary

Programmatically generated summary. Hog Says

24 wave-buoy observations were recorded during the day. Typical wave height was 6.5 ft (10th–90th percentile 6.2–7.6 ft), while mean peak wave period was 10.7 seconds (10th–90th percentile 10.2–11.1 seconds). All 72 checked values passed quality control.

Generated only from the observations and comparisons shown on this page.

About Bilbao-Vizcaya wave buoy

Bilbao-Vizcaya is a Puertos del Estado REDEXT deep-water buoy moored in roughly 580 metres of water in the Bay of Biscay. Its offshore setting captures open-sea conditions before they are transformed by the continental shelf and coast, supporting forecasts and operations for Bilbao and the Basque ports.

Its current data source reports wave height, wave period and wave direction.

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.
