Last wave reading:
Now at the buoy
Significant wave height at the buoy
1.3 ft

- no direction
This reading came without the swell and wind-wave split, so the numbers are for the whole sea.
Short-period wind chop: 1.3 ft at 5 s. 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.

How to read this buoy
UTMSI_BUOY_3 - Hydro List 1415.01 (SPOT-33553C) sits close to shore, 5.4 km from the closest beach listed here. Its readings already include some of the local shadowing, so they track nearby beaches more closely than an offshore buoy.
Biggest hourly reading in that record: 6.9 ft at 6.5 s on Nov 8.

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.
