Significant wave height at the buoy
0.3 ft
0.1 m
- Dominant period
- —
- Direction
- from SE 124°
This reading came without the swell and wind-wave split, so the numbers are for the whole sea.
Close to flat at the buoy: 0.3 ft of total wave height.
Significant wave height is the average of the biggest third of waves at the buoy. It is not surf height at a beach.

Buoy terms
- Significant height
- The average of the biggest third of waves the buoy measured. Sets in the surf zone can be bigger or smaller.
- Dominant period
- Seconds between the waves carrying the most energy. Longer period means more power and more bend around points.
- Swell vs wind waves
- Swell was made by distant wind; wind waves were made nearby. The buoy splits its spectrum at a cutoff period to report each.
- Direction
- Where waves come from, in degrees true. 270° is from the west.
