Period Summary

Programmatically generated summary. Hog Says

737 wave-buoy observations covered all 31 days. Typical wave height was 4.9 ft (10th–90th percentile 2.6–11.2 ft), while mean reported wave period; measurement type unavailable was 5.3 seconds (10th–90th percentile 4–7 seconds). Typical wind was 15 mph (10th–90th percentile 5.8–25.3 mph) and mean water temperature was 14.7°C (10th–90th percentile 13.3–17.2°C). All 3,567 checked values passed quality control. Across 4 comparable years, mean wave height was above the same-month mean of 4.2 ft and mean wave period was above the same-month mean of 4.6 seconds.

About Anasuria AWS wave buoy

Anasuria AWS (WMO 62164) is an automatic weather station on privately operated offshore infrastructure in the central North Sea. It is not a free-floating wave buoy. The station contributes meteorological and, when fitted, sea-state observations from an area with extensive offshore energy activity.

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.

Which wave period is shown?

The table shows the best period measurement supplied for each observation. It is not necessarily the energy period used to calculate wave power.

Tp
Peak period: the period at the strongest spectral peak.
Tavg
The provider's average wave period.
Tm02
A mean period calculated from the wave spectrum.
Tz
Mean zero-crossing period.
Reported
A legacy value whose period type was not recorded.
Mixed
A daily or monthly mean containing more than one period type.

Wave power needs a genuine energy period (Te). SurfHog does not substitute Tp, Tavg, Tm02 or Tz when Te is missing.

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.
