Primary target in that timeframe will be stripers. Sept in Oct there will be some bluefish as well.
Depending on the bait movement, the bass will be feeding on mullet, peanut bunker, adult bunker and sandeels. The sandeels will be what they feed on into December.
So if you're fishing bait, bunker chunks, mullet and peanut bunker would be choices early on. Clams later on in the fall.
If you're fishing artificials, swimming plugs and poppers early on. And AVAs, needlefish and other skinny lures later on.
The beaches further south (southern monmouth co. and most of ocean co.) are typically much more productive in the fall. But every year is different.
Your best chance for success is to be willing to try different areas as the fish migrate.
