NOAA

There aren't many organizations that work with as much data as the
National Oceanic and Atmospheric Administration. NOAA provides
weather information in multiple ways including a Web site and radio
stations.

At night and early in the morning we check the site and the radio.
What if NOAA is wrong. For instance, southwest winds at 10 knots is
really northwest winds at 20 knots with 4-6 foot seas. That was our
morning.
