My landlord is a huge windsurfing guy, and a code engineer to boot. He has a blog, linked below, and works from home and constantly is updated with weather info.
On the right of the blog is the weather apps he uses to forecast offshore conditions here in northern OBX for windsurfing. You guys need to check these out.
Pay particular attention to the windguru link, that is awesome info for us smaller boats getting to and from the gulfstream. And, everything is there, sea surface and all.
