Significant wave height at the buoy

2.3 ft

0.7 m

Dominant period
3 s
Direction
from NW 322°

This reading came without the swell and wind-wave split, so the numbers are for the whole sea.

Short-period wind chop: 2.3 ft at 3 s from the NW. 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.
