What NOAA buoy 41004 measures
As a NOAA meteorological station, 41004 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 Edisto?
- Sea surface temperature at Edisto was 78°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Edisto?
- Air temperature at Edisto was 65°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC).
- What is the wind doing at Edisto?
- Wind at Edisto was from the NNE at 20 mph, with peak gusts to 27 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC). 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 Edisto?
- Significant wave height at Edisto was 8.9 ft, with a 13-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC). 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 Edisto?
- Waves at Edisto were arriving from 92° true (E) at the dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC).
- What is the barometric pressure at Edisto?
- Sea-level pressure at Edisto was 30.21 inHg (1022.9 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- What is the swell at Edisto?
- The swell at Edisto had a significant height of 6.6 ft at a 13-second peak period, arriving from the E. Measured October 19, 2026 at 18:40 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Edisto?
- The wind-wave component at Edisto had a significant height of 5.9 ft at an 8-second peak period, from the ENE. Measured October 19, 2026 at 18:40 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Edisto?
- NDBC classified the sea state at Edisto as swell, with a significant wave height of 8.9 ft. Measured October 19, 2026 at 18:40 UTC by NOAA station 41004 (EDISTO - 41 NM Southeast of Charleston, SC). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 41004 located?
- EDISTO - 41 NM Southeast of Charleston, SC (41004) reports from 32.502°N, 79.099°W in the western North Atlantic (South Carolina).
- How often is NOAA buoy 41004 updated?
- Station 41004 typically reports new observations about every 10 minutes. Big Buoy refreshes continuously so you always see the latest readings, alongside 7-day tide predictions and a solunar table for the area.
- What does NOAA buoy 41004 measure?
