Now at the buoy

Significant wave height at the buoy

5.3 ft

1.6 m

Dominant period: 11 s
Direction: from WSW 248°

This station does not send a swell and wind-wave split, so the numbers are for the whole sea.

Mid-period swell: 5.3 ft at 11 s from the WSW. Holding steady over the last 6 hours.

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.
