Southern Jersey is beautiful.
I don't think the striped ones will be down that way then, they're ours till October
If you're near Ocean City, NJ - there is a nice park called Corsons Inlet that will give up blues and fluke. Get a minnow trap and use salami for bait in any of the marshes, you'll get more chubs (minnows) than you know what to do with.
Following the coast from OC to Cape May - any of the bridges that lead to the ocean will give up blues and maybe a weakfish. I had a blast casting a black swimmer, caught blues one after another. I don't remember if I was in Avalon or Sea Isle City.
This is the first time in 7years my family is not vacationing there, I miss it already.
Good Luck
