This reading is more than 3 hours old. The buoy may have stopped sending waves for now.
Significant wave height at the buoy
0.0 ft
0.0 m
- Dominant period
- —
- Direction
- from N 0°
This station does not send a swell and wind-wave split, so the numbers are for the whole sea.
Close to flat at the buoy: 0.0 ft of total wave height.
Significant wave height is the average of the biggest third of waves at the buoy. It is not surf height at a beach.

ECMWF WAM wave model via Open-Meteo, nearest model cell (35.500°N, 25.000°E). Both lines are significant wave height at sea, the same measure the buoy reports. Model output, not a Quiver beach forecast.

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.
