How to read this buoy
Astoria Canyon, OR sits in open water, 50 km from the closest beach listed here. It sees swell before the coast bends, blocks or shrinks it, so expect beach surf to differ from this reading.
Over the readings shown here, most wave energy reached this buoy from the W and NW.
Biggest hourly reading in that record: 23.3 ft at 14 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.
