What NOAA buoy 41025 measures
As a NOAA meteorological station, 41025 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 western North Atlantic
Conditions along the Atlantic coast are driven by swell direction and the shifting western edge of the Gulf Stream. Northeast winds against an outgoing tide stack up steep, dangerous seas at inlets, and water temperature can change 10–20°F over just a few miles as the Gulf Stream boundary moves.
Frequently asked questions
- What is the water temperature at Diamond Shoals?
- Sea surface temperature at Diamond Shoals was 70°F. Measured October 19, 2026 at 19:20 UTC by NOAA station 41025 (Diamond Shoals, NC). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Diamond Shoals?
- Air temperature at Diamond Shoals was 65°F. Measured October 19, 2026 at 19:20 UTC by NOAA station 41025 (Diamond Shoals, NC).
- What is the wind doing at Diamond Shoals?
- Wind at Diamond Shoals was from the N at 36 mph, with peak gusts to 45 mph. Measured October 19, 2026 at 19:20 UTC by NOAA station 41025 (Diamond Shoals, NC). 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 Diamond Shoals?
- Significant wave height at Diamond Shoals was 16.1 ft, with a 13-second dominant period. Measured October 19, 2026 at 19:20 UTC by NOAA station 41025 (Diamond Shoals, NC). 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 Diamond Shoals?
- Waves at Diamond Shoals were arriving from 67° true (ENE) at the dominant period. Measured October 19, 2026 at 19:20 UTC by NOAA station 41025 (Diamond Shoals, NC).
- What is the barometric pressure at Diamond Shoals?
- Sea-level pressure at Diamond Shoals was 30.10 inHg (1019.2 hPa). Measured October 19, 2026 at 19:20 UTC by NOAA station 41025 (Diamond Shoals, NC). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- Is it swell or wind chop at Diamond Shoals?
- NDBC classified the sea state at Diamond Shoals as average, with a significant wave height of 16.1 ft. Measured October 19, 2026 at 19:10 UTC by NOAA station 41025 (Diamond Shoals, NC). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 41025 located?
- Diamond Shoals, NC (41025) reports from 35.026°N, 75.380°W in the western North Atlantic (North Carolina).
- How often is NOAA buoy 41025 updated?
