What NOAA buoy 46248 measures
As a NOAA meteorological station, 46248 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 Astoria Canyon?
- Sea surface temperature at Astoria Canyon was 57°F. Measured October 19, 2026 at 19:26 UTC by NOAA station 46248 (Astoria Canyon, OR (179)). NDBC measures this near the surface, at a depth that varies by station.
- How big are the waves at Astoria Canyon?
- Significant wave height at Astoria Canyon was 5.2 ft, with a 12-second dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46248 (Astoria Canyon, OR (179)). 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 Astoria Canyon?
- Waves at Astoria Canyon were arriving from 295° true (WNW) at the dominant period. Measured October 19, 2026 at 19:26 UTC by NOAA station 46248 (Astoria Canyon, OR (179)).
- What is the swell at Astoria Canyon?
- The swell at Astoria Canyon had a significant height of 3.9 ft at a 12-second peak period, arriving from the WNW. Measured October 19, 2026 at 19:26 UTC by NOAA station 46248 (Astoria Canyon, OR (179)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Astoria Canyon?
- The wind-wave component at Astoria Canyon had a significant height of 3.6 ft at a 9-second peak period, from the W. Measured October 19, 2026 at 19:26 UTC by NOAA station 46248 (Astoria Canyon, OR (179)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Astoria Canyon?
- NDBC classified the sea state at Astoria Canyon as swell, with a significant wave height of 5.2 ft. Measured October 19, 2026 at 19:26 UTC by NOAA station 46248 (Astoria Canyon, OR (179)). The classification describes wave steepness relative to period, not wave size.
