Last wave reading: Nov 12, 5:20 PM GMT+3

Last reading

This reading is more than 3 hours old. The buoy may have stopped sending waves for now.

Significant wave height at the buoy

2.6 ft

0.8 m

Dominant period: —
Direction: no direction

This station does not send a swell and wind-wave split, so the numbers are for the whole sea.

Waves: 2.6 ft.

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 (12.500°S, 45.000°E). Both lines are significant wave height at sea, the same measure the buoy reports. Model output, not a Quiver beach forecast.

How to read this buoy

Biggest hourly reading in that record: 3.6 ft on Nov 11.

Operator: Cerema
Program: Copernicus Marine In Situ
Position: 12.550°S, 45.067°E
Type: Moored buoy
Local time zone: Asia/Riyadh
Swell split: No, whole-sea numbers only

Source: E.U. Copernicus Marine Service Information; https://doi.org/10.48670/moi-00036. Data from Cerema. Licence: Copernicus Marine Service licence. Changes: Quiver converts the units (feet, knots, °F) and shows a subset of the published fields.

Not for navigation. Readings can be late, missing or wrong; check official marine forecasts before going to sea.

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.
