What NOAA buoy 46069 measures
As a NOAA meteorological station, 46069 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 South Santa Rosa?
- Sea surface temperature at South Santa Rosa was 70°F. Measured October 19, 2026 at 19:30 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at South Santa Rosa?
- Air temperature at South Santa Rosa was 67°F. Measured October 19, 2026 at 19:30 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA).
- What is the wind doing at South Santa Rosa?
- Wind at South Santa Rosa was from the NW at 20 mph, with peak gusts to 25 mph. Measured October 19, 2026 at 19:30 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, 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 South Santa Rosa?
- Significant wave height at South Santa Rosa was 9.2 ft, with a 15-second dominant period. Measured October 19, 2026 at 19:30 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, 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 South Santa Rosa?
- Waves at South Santa Rosa were arriving from 241° true (WSW) at the dominant period. Measured October 19, 2026 at 19:30 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA).
- What is the barometric pressure at South Santa Rosa?
- Sea-level pressure at South Santa Rosa was 29.96 inHg (1014.6 hPa). Measured October 19, 2026 at 19:30 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- What is the swell at South Santa Rosa?
- The swell at South Santa Rosa had a significant height of 7.5 ft at a 15-second peak period, arriving from the WSW. Measured October 19, 2026 at 19:10 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at South Santa Rosa?
- The wind-wave component at South Santa Rosa had a significant height of 4.9 ft at an 8-second peak period, from the NW. Measured October 19, 2026 at 19:10 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at South Santa Rosa?
- NDBC classified the sea state at South Santa Rosa as swell, with a significant wave height of 9.2 ft. Measured October 19, 2026 at 19:10 UTC by NOAA station 46069 (SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 46069 located?
- SOUTH SANTA ROSA - 14 NM SW of Santa Rosa Island, CA (46069) reports from 33.657°N, 120.227°W in the eastern North Pacific (California).
- How often is NOAA buoy 46069 updated?
- Station 46069 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 46069 measure?
