What NOAA buoy 46232 measures
As a NOAA meteorological station, 46232 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 Point Loma South?
- Sea surface temperature at Point Loma South was 74°F. Measured October 19, 2026 at 19:26 UTC by NOAA station 46232 (Point Loma South, CA (191)). NDBC measures this near the surface, at a depth that varies by station.
- How big are the waves at Point Loma South?
- Significant wave height at Point Loma South was 4.6 ft, with a 17-second dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46232 (Point Loma South, CA (191)). 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 Point Loma South?
- Waves at Point Loma South were arriving from 176° true (S) at the dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46232 (Point Loma South, CA (191)).
- What is the swell at Point Loma South?
- The swell at Point Loma South had a significant height of 4.3 ft at a 17-second peak period, arriving from the S. Measured October 19, 2026 at 19:26 UTC by NOAA station 46232 (Point Loma South, CA (191)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Point Loma South?
- The wind-wave component at Point Loma South had a significant height of 1.6 ft at a 10-second peak period, from the WSW. Measured October 19, 2026 at 19:26 UTC by NOAA station 46232 (Point Loma South, CA (191)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Point Loma South?
- NDBC classified the sea state at Point Loma South as swell, with a significant wave height of 4.6 ft. Measured October 19, 2026 at 19:26 UTC by NOAA station 46232 (Point Loma South, CA (191)). The classification describes wave steepness relative to period, not wave size.
