What NOAA buoy 46275 measures
As a NOAA meteorological station, 46275 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 Red Beach Nearshore?
- Sea surface temperature at Red Beach Nearshore was 73°F. Measured October 19, 2026 at 21:00 UTC by NOAA station 46275 (Red Beach Nearshore, CA (264)). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Red Beach Nearshore?
- Air temperature at Red Beach Nearshore was 73°F. Measured October 19, 2026 at 21:00 UTC by NOAA station 46275 (Red Beach Nearshore, CA (264)).
- How big are the waves at Red Beach Nearshore?
- Significant wave height at Red Beach Nearshore was 4.3 ft, with a 17-second dominant period. Measured October 19, 2026 at 21:00 UTC by NOAA station 46275 (Red Beach Nearshore, CA (264)). 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 Red Beach Nearshore?
- Waves at Red Beach Nearshore were arriving from 214° true (SW) at the dominant period. Measured October 19, 2026 at 21:00 UTC by NOAA station 46275 (Red Beach Nearshore, CA (264)).
- What is the swell at Red Beach Nearshore?
- The swell at Red Beach Nearshore had a significant height of 3.9 ft at a 17-second peak period, arriving from the SW. Measured October 19, 2026 at 21:00 UTC by NOAA station 46275 (Red Beach Nearshore, CA (264)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Red Beach Nearshore?
- The wind-wave component at Red Beach Nearshore had a significant height of 1.3 ft at a 10-second peak period, from the WSW. Measured October 19, 2026 at 21:00 UTC by NOAA station 46275 (Red Beach Nearshore, CA (264)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Red Beach Nearshore?
- NDBC classified the sea state at Red Beach Nearshore as swell, with a significant wave height of 3.9 ft. Measured October 19, 2026 at 21:00 UTC by NOAA station 46275 (Red Beach Nearshore, CA (264)). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 46275 located?
- Red Beach Nearshore, CA (264) (46275) reports from 33.291°N, 117.501°W in the eastern North Pacific (California).
- How often is NOAA buoy 46275 updated?
- Station 46275 typically reports new observations about every 10 minutes. Big Buoy refreshes continuously so you always see the latest readings, alongside 7-day tide predictions and a solunar table for the area.
- What does NOAA buoy 46275 measure?
- Big Buoy shows wind, barometric pressure, air and water temperature, and wave height and period where available for Red Beach Nearshore, CA (264), plus 7-day tides, solunar peak windows, and a multi-day weather outlook.
- Is Big Buoy free to use?
- Yes. Live data for Red Beach Nearshore, CA (264) and every other NOAA buoy is free with no account required. Big Buoy Pro adds the Wind Tab, the Depth Chart, satellite overlays (sea surface temp, chlorophyll, currents), 16-day forecasts, and forecast model switching.
