What NOAA buoy 46086 measures
As a NOAA meteorological station, 46086 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 San Clemente Basin?
- Sea surface temperature at San Clemente Basin was 73°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, CA). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at San Clemente Basin?
- Air temperature at San Clemente Basin was 69°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, CA).
- What is the wind doing at San Clemente Basin?
- Wind at San Clemente Basin was from the WNW at 11 mph, with peak gusts to 13 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, 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 San Clemente Basin?
- Significant wave height at San Clemente Basin was 5.9 ft, with a 16-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, 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 San Clemente Basin?
- Waves at San Clemente Basin were arriving from 162° true (SSE) at the dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, CA).
- What is the barometric pressure at San Clemente Basin?
- Sea-level pressure at San Clemente Basin was 29.93 inHg (1013.6 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, CA). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- What is the swell at San Clemente Basin?
- The swell at San Clemente Basin had a significant height of 5.6 ft at a 16-second peak period, arriving from the SSE. Measured October 19, 2026 at 18:40 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, CA). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at San Clemente Basin?
- The wind-wave component at San Clemente Basin had a significant height of 1.0 ft at a 4-second peak period, from the WNW. Measured October 19, 2026 at 18:40 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, CA). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at San Clemente Basin?
- NDBC classified the sea state at San Clemente Basin as swell, with a significant wave height of 5.9 ft. Measured October 19, 2026 at 18:40 UTC by NOAA station 46086 (SAN CLEMENTE BASIN - 27NM SE Of San Clemente Is, CA). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 46086 located?
