What NOAA buoy 44029 measures
As a NOAA meteorological station, 44029 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.
