Surf may be slow, but try IRI and 3 Rs.
Also, there's some bridge (or two) just west of Fenwick/Bethany area that supposedly has some nice resident striper activity. Check at Fenwick tackle and maybe they can point you in the right direction. I've never fished there but have seen a couple nice ones brought in to the tackle shop from there.
A little further south you can try Homer Gudulsky Park (aka Stinky Beach) for some hickory shad action. Fish the rips area at the right side of the beach, casting out maybe 100 ft with a tandem jig rig (1/4 and 1/2 oz bucktail style) or gotcha plugs.
The OC Inlet jetty is another god place for early blues mixed with shad. Fish the north jetty on the end, but on the beach side ... cast out from 10:00 to 11:00 direction.
