What NOAA buoy 44084 measures
As a NOAA meteorological station, 44084 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 Bethany Beach?
- Sea surface temperature at Bethany Beach was 63°F. Measured October 19, 2026 at 18:26 UTC by NOAA station 44084 (Bethany Beach, DE (263)). NDBC measures this near the surface, at a depth that varies by station.
- How big are the waves at Bethany Beach?
- Significant wave height at Bethany Beach was 6.6 ft, with an 8-second dominant period. Measured October 19, 2026 at 18:26 UTC by NOAA station 44084 (Bethany Beach, DE (263)). 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 Bethany Beach?
- Waves at Bethany Beach were arriving from 85° true (E) at the dominant period. Measured October 19, 2026 at 18:26 UTC by NOAA station 44084 (Bethany Beach, DE (263)).
- What is the swell at Bethany Beach?
- The swell at Bethany Beach had a significant height of 1.6 ft at an 11-second peak period, arriving from the E. Measured October 19, 2026 at 18:26 UTC by NOAA station 44084 (Bethany Beach, DE (263)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Bethany Beach?
- The wind-wave component at Bethany Beach had a significant height of 6.2 ft at an 8-second peak period, from the E. Measured October 19, 2026 at 18:26 UTC by NOAA station 44084 (Bethany Beach, DE (263)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Bethany Beach?
- NDBC classified the sea state at Bethany Beach as steep, with a significant wave height of 6.6 ft. Measured October 19, 2026 at 18:26 UTC by NOAA station 44084 (Bethany Beach, DE (263)). The classification describes wave steepness relative to period, not wave size.
