What NOAA buoy 46029 measures
As a NOAA meteorological station, 46029 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 Columbia River Bar?
- Sea surface temperature at Columbia River Bar was 56°F. Measured October 19, 2026 at 18:50 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Columbia River Bar?
- Air temperature at Columbia River Bar was 54°F. Measured October 19, 2026 at 18:50 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth).
- What is the wind doing at Columbia River Bar?
- Wind at Columbia River Bar was from the SSE at 11 mph, with peak gusts to 13 mph. Measured October 19, 2026 at 18:50 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth). 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 Columbia River Bar?
- Significant wave height at Columbia River Bar was 5.6 ft, with an 11-second dominant period. Measured October 19, 2026 at 18:50 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth). 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 Columbia River Bar?
- Waves at Columbia River Bar were arriving from 298° true (WNW) at the dominant period. Measured October 19, 2026 at 18:50 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth).
- What is the barometric pressure at Columbia River Bar?
- Sea-level pressure at Columbia River Bar was 29.96 inHg (1014.6 hPa). Measured October 19, 2026 at 18:50 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- What is the swell at Columbia River Bar?
- The swell at Columbia River Bar had a significant height of 5.2 ft at an 11-second peak period, arriving from the WNW. Measured October 19, 2026 at 18:40 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Columbia River Bar?
- The wind-wave component at Columbia River Bar had a significant height of 2.0 ft at a 4-second peak period, from the SSE. Measured October 19, 2026 at 18:40 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Columbia River Bar?
- NDBC classified the sea state at Columbia River Bar as swell, with a significant wave height of 5.6 ft. Measured October 19, 2026 at 18:40 UTC by NOAA station 46029 (COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 46029 located?
- COLUMBIA RIVER BAR - 20NM West of Columbia River Mouth (46029) reports from 46.148°N, 124.508°W in the eastern North Pacific.
- How often is NOAA buoy 46029 updated?
