Here is another useful source of sea information:
http://www.ndbc.noaa.gov/dial.shtml
This one allows you to call and get detailed information from the weather buoys.
If you call 888-701-8992 and key in 41114 as the station ID you will get the data for the buoy off of Ft. Pierce. Pay close attention to the date and time from the recording though. I have seen a few times where it does not update for a few days. Also, I find the detailed wave information at the end of the message to be more useful. You will get a feel for what the buoy says vs the actual sea conditions in time.
