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.
