What NOAA buoy 46224 measures
As a NOAA meteorological station, 46224 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 Oceanside Offshore?
- Sea surface temperature at Oceanside Offshore was 73°F. Measured October 19, 2026 at 19:56 UTC by NOAA station 46224 (Oceanside Offshore, CA (045)). NDBC measures this near the surface, at a depth that varies by station.
- How big are the waves at Oceanside Offshore?
- Significant wave height at Oceanside Offshore was 4.3 ft, with a 17-second dominant period. Measured October 19, 2026 at 19:56 UTC by NOAA station 46224 (Oceanside Offshore, CA (045)). 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 Oceanside Offshore?
- Waves at Oceanside Offshore were arriving from 202° true (SSW) at the dominant period. Measured October 19, 2026 at 19:56 UTC by NOAA station 46224 (Oceanside Offshore, CA (045)).
- What is the swell at Oceanside Offshore?
- The swell at Oceanside Offshore had a significant height of 4.6 ft at a 15-second peak period, arriving from the SSW. Measured October 19, 2026 at 20:26 UTC by NOAA station 46224 (Oceanside Offshore, CA (045)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Oceanside Offshore?
- The wind-wave component at Oceanside Offshore had a significant height of 1.6 ft at a 10-second peak period, from the W. Measured October 19, 2026 at 20:26 UTC by NOAA station 46224 (Oceanside Offshore, CA (045)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Oceanside Offshore?
- NDBC classified the sea state at Oceanside Offshore as swell, with a significant wave height of 4.6 ft. Measured October 19, 2026 at 20:26 UTC by NOAA station 46224 (Oceanside Offshore, CA (045)). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 46224 located?
- Oceanside Offshore, CA (045) (46224) reports from 33.178°N, 117.472°W in the eastern North Pacific (California).
- How often is NOAA buoy 46224 updated?
- Station 46224 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 46224 measure?
- Big Buoy shows wind, barometric pressure, air and water temperature, and wave height and period where available for Oceanside Offshore, CA (045), plus 7-day tides, solunar peak windows, and a multi-day weather outlook.
- Is Big Buoy free to use?
- Yes. Live data for Oceanside Offshore, CA (045) 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.
