How to read this buoy
Neah Bay - 6 NM North of Cape Flattery, WA (Traffic Separation Lighted Buoy) sits 18 km from the closest beach listed here: near enough to show what is arriving, far enough that islands, points and the seabed still change it before it breaks.
Over the readings shown here, most wave energy reached this buoy from the W.
Biggest hourly reading in that record: 25.1 ft at 15 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.
