The NOAA forecasts are notoriously inaccurate. They are quite poor a lot of the time.
The best use is to watch for fronts. Usually the passage of the front denotes stronger wind and wind direction. Usually once the front passes the winds are Northerly (a lot of the times they are North West). The buoy reports are also helpful because they give you wind speed, direction, and wave height.
I use several wind, wave, and weather apps on my iPhone. I will listen to NOAA for the storm warnings as well, but I have found watching the radar on the phone and having a weatherbug app is priceless.
