If the wind is relatively calm and the water is relatively clear, try the surf at dawn. I prefer the beachfront closer to the west end of the island. You can get live shrimp at the Sea Isle marina or a few miles to the west at the Rusty Hook. I like to fish anywhere from the Sea Isle beach access to the water tower near the western tip of the island. If the surf is too rough or dirty, you can access the bay at 8-mile road, which is right where you are staying, or at the State Park a little to the west, or at the Sea Isle fishing pier (you need a pass to get on the pier, but can park there and access the bay without the pass). Some like to fish at San Luis Pass, but I have not had much luck there. You also need to be very careful if you go to the pass due to the strong currents.
