Period Summary

Programmatically generated summary. Hog Says

1,448 wave-buoy observations covered all 31 days. Typical wave height was 2.5 ft (10th–90th percentile 0.9–6.5 ft), while mean average of more than one wave period type was 4.2 seconds (10th–90th percentile 3–5.3 seconds). All 4,332 checked values passed quality control. Across 9 comparable years, mean wave height was above the same-month mean of 3 ft and mean wave period was the same as the same-month mean of 4.2 seconds.

About Nymindegab wave buoy

Nymindegab is a Danish Coastal Authority directional buoy in the North Sea off the southern part of Jutland's exposed west coast. The station supports long-term understanding and management of the sandy barrier coast around the southern end of Ringkøbing Fjord and the Lodbjerg–Nymindegab protection area.

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

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.

The observation data displayed on this page is from the Danish Coastal Authority wave-measurement network.
