My grandpa used to have a house there. DW is right - there will be tons of snapper blues around. At high tide in the middle of the day you can find them hiding under docks and piers. Most of the ones I caught down there were under 10", the bigger ones will be out in the bay toward the inlet. Big flounder over there too, but may not be accessible with a fly rod.
Also around the docks, you'll find spot and black sea bass up to about 8". A lot of fun on light tackle. Actually never caught a spot on the fly but the BSB's are greedy and will eat those same small clousers that the snapper blues will. They hang out very close to the pilings, near the bottom.
