What NOAA buoy 41008 measures
As a NOAA meteorological station, 41008 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 air temperature at Grays Reef?
- Air temperature at Grays Reef was 64°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA).
- What is the wind doing at Grays Reef?
- Wind at Grays Reef was from the N at 16 mph, with peak gusts to 20 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA). 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 Grays Reef?
- Significant wave height at Grays Reef was 6.2 ft, with a 14-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA). 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 Grays Reef?
- Waves at Grays Reef were arriving from 101° true (E) at the dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA).
- What is the barometric pressure at Grays Reef?
- Sea-level pressure at Grays Reef was 30.22 inHg (1023.3 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- What is the swell at Grays Reef?
- The swell at Grays Reef had a significant height of 3.9 ft at a 14-second peak period, arriving from the E. Measured October 19, 2026 at 18:40 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Grays Reef?
- The wind-wave component at Grays Reef had a significant height of 4.6 ft at a 6-second peak period, from the ENE. Measured October 19, 2026 at 18:40 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Grays Reef?
- NDBC classified the sea state at Grays Reef as average, with a significant wave height of 6.2 ft. Measured October 19, 2026 at 18:40 UTC by NOAA station 41008 (GRAYS REEF - 40 NM Southeast of Savannah, GA). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 41008 located?
- GRAYS REEF - 40 NM Southeast of Savannah, GA (41008) reports from 31.400°N, 80.866°W in the western North Atlantic (Georgia).
- How often is NOAA buoy 41008 updated?
