What NOAA buoy PORT2 measures
As a NOAA meteorological station, PORT2 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 Gulf of Mexico
The Gulf’s shallow, broad shelf means seas build and lay down quickly with the wind — short-period chop is the norm rather than long ocean swell. Summer afternoons bring fast-developing thunderstorms, so watch barometric pressure and wind trends closely before heading out.
