NOAA maintains data buoys all along U.S. coasts and elsewhere in the world, such as this one off Boston. These buoys gather a range of information about weather and sea conditions, including:
- Current and recent wind speed and direction
- Wave height and period
- Atmospheric pressure and trending
- Air and water temperature
You should know the current weather conditions before and while sailing. The next pages show you how to access this buoy information via the Internet or with a cell phone while underway.
