What NOAA buoy 46219 measures
As a NOAA meteorological station, 46219 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 San Nicolas Island?
- Sea surface temperature at San Nicolas Island was 70°F. Measured October 19, 2026 at 19:26 UTC by NOAA station 46219 (San Nicolas Island, CA (067)). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at San Nicolas Island?
- Air temperature at San Nicolas Island was 69°F. Measured October 19, 2026 at 19:26 UTC by NOAA station 46219 (San Nicolas Island, CA (067)).
- How big are the waves at San Nicolas Island?
- Significant wave height at San Nicolas Island was 8.2 ft, with a 13-second dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46219 (San Nicolas Island, CA (067)). 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 San Nicolas Island?
- Waves at San Nicolas Island were arriving from 293° true (WNW) at the dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46219 (San Nicolas Island, CA (067)).
- What is the swell at San Nicolas Island?
- The swell at San Nicolas Island had a significant height of 5.9 ft at a 13-second peak period, arriving from the WNW. Measured October 19, 2026 at 19:26 UTC by NOAA station 46219 (San Nicolas Island, CA (067)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at San Nicolas Island?
- The wind-wave component at San Nicolas Island had a significant height of 5.9 ft at a 10-second peak period, from the NW. Measured October 19, 2026 at 19:26 UTC by NOAA station 46219 (San Nicolas Island, CA (067)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at San Nicolas Island?
- NDBC classified the sea state at San Nicolas Island as swell, with a significant wave height of 8.2 ft. Measured October 19, 2026 at 19:26 UTC by NOAA station 46219 (San Nicolas Island, CA (067)). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 46219 located?
- San Nicolas Island, CA (067) (46219) reports from 33.226°N, 119.891°W in the eastern North Pacific (California).
- How often is NOAA buoy 46219 updated?
