Here is a weather site I have had good results using when planning when to cross the corner of the Gulf.
Tampa Bay Surf Report (STORMSURF)
When it opens it will show the Gulf off Tampa Bay, just scroll down to the "MWxPro Control Panel". In the "Gulf of Mexico" line click on the "Sea height" Icon it will give you several days forecast at 6 hr intervals, you can pause or back it up using symbols the screen image.
If you have to wait for good weather head up to Tarpon Springs, it is a great place to stop.
Good Luck!
