Just make sure you rinse your rod and reel with freshwater really well after fishing. Unless you have a saltwater reel or one with a sealed drag system, you want to keep it free of salt.

As for the fishing, I like to cast parallel to the bank when surf fishing. If you can wade out to a sandbar or some higher ground and fish all the troughs around it, that is pretty productive too.

Surf fishing is tough with a fly rod, but it can be done. Good luck!
