What NOAA buoy 46211 measures
As a NOAA meteorological station, 46211 reports wind speed, gusts and direction, barometric pressure, air and water temperature, and — where wave sensors are fitted — significant wave height, swell period, and wave direction.
What to watch in the eastern North Pacific
The U.S. Pacific coast is dominated by long-period groundswell and strong seasonal upwelling that keeps nearshore water cold. Watch swell period as closely as wave height — a long-period west swell can make harbor entrances and bar crossings hazardous even when the wave height looks modest.
Frequently asked questions
- What is the water temperature at Grays Harbor?
- Sea surface temperature at Grays Harbor was 55°F. Measured October 19, 2026 at 19:26 UTC by NOAA station 46211 (Grays Harbor, WA (036)). NDBC measures this near the surface, at a depth that varies by station.
- How big are the waves at Grays Harbor?
- Significant wave height at Grays Harbor was 4.9 ft, with an 11-second dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46211 (Grays Harbor, WA (036)). Significant wave height is the average of the highest one-third of waves — individual waves can be larger.
- Which direction are the waves coming from at Grays Harbor?
- Waves at Grays Harbor were arriving from 278° true (W) at the dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46211 (Grays Harbor, WA (036)).
- What is the swell at Grays Harbor?
- The swell at Grays Harbor had a significant height of 3.0 ft at an 11-second peak period, arriving from the W. Measured October 19, 2026 at 19:26 UTC by NOAA station 46211 (Grays Harbor, WA (036)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Grays Harbor?
- The wind-wave component at Grays Harbor had a significant height of 3.6 ft at a 9-second peak period, from the WNW. Measured October 19, 2026 at 19:26 UTC by NOAA station 46211 (Grays Harbor, WA (036)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Grays Harbor?
- NDBC classified the sea state at Grays Harbor as average, with a significant wave height of 4.9 ft. Measured October 19, 2026 at 19:26 UTC by NOAA station 46211 (Grays Harbor, WA (036)). The classification describes wave steepness relative to period, not wave size.
