What NOAA buoy WASD2 measures
As a NOAA meteorological station, WASD2 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 NOAA buoy WASD2?
- Sea surface temperature at NOAA buoy WASD2 was 65°F. Measured October 19, 2026 at 20:00 UTC by NOAA station WASD2 (8594900 - Washington, DC). NDBC measures this near the surface, at a depth that varies by station.
