Period Summary

Programmatically generated summary. Hog Says

24 wave-buoy observations were recorded during the day. Typical wave height was 1.9 ft (10th–90th percentile 1.5–2.3 ft), while mean peak wave period was 7.8 seconds (10th–90th percentile 5.7–8.6 seconds). All 72 checked values passed quality control.

About Golfo de Cádiz wave buoy

Golfo de Cádiz is a Puertos del Estado REDEXT buoy moored in about 450 metres of water off southwest Spain. It provides an open-water reference for the broad gulf between Cape St Vincent and the Strait of Gibraltar, relevant to Andalusian and Algarve coasts and their major shipping routes.

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

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.

The observation data displayed on this page is from the Puertos del Estado Portus network.
