What NOAA buoy 46025 measures
As a NOAA meteorological station, 46025 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 Santa Monica Basin?
- Sea surface temperature at Santa Monica Basin was 73°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Santa Monica Basin?
- Air temperature at Santa Monica Basin was 71°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA).
- What is the wind doing at Santa Monica Basin?
- Wind at Santa Monica Basin was from the WSW at 2 mph, with peak gusts to 4 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA). NDBC records wind at the station’s anemometer height, which is not the 10 m height used in marine forecasts.
- How big are the waves at Santa Monica Basin?
- Significant wave height at Santa Monica Basin was 4.6 ft, with a 16-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA). 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 Santa Monica Basin?
- Waves at Santa Monica Basin were arriving from 191° true (S) at the dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA).
- What is the barometric pressure at Santa Monica Basin?
- Sea-level pressure at Santa Monica Basin was 29.93 inHg (1013.6 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- What is the swell at Santa Monica Basin?
- The swell at Santa Monica Basin had a significant height of 4.6 ft at a 16-second peak period, arriving from the S. Measured October 19, 2026 at 18:40 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Santa Monica Basin?
- The wind-wave component at Santa Monica Basin had a significant height of 1.0 ft at a 4-second peak period, from the W. Measured October 19, 2026 at 18:40 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Santa Monica Basin?
- NDBC classified the sea state at Santa Monica Basin as swell, with a significant wave height of 4.6 ft. Measured October 19, 2026 at 18:40 UTC by NOAA station 46025 (Santa Monica Basin - 33NM WSW of Santa Monica, CA). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 46025 located?
- Santa Monica Basin - 33NM WSW of Santa Monica, CA (46025) reports from 33.765°N, 119.077°W in the eastern North Pacific (California).
