Boat Fishing at that time of the year is much more productive than shore fishing, and even if you had have traveled down to the Cape, you might have struggled a bit from the shore, especially so during the day.....Heat and the seals would be the main problems. Sport is normally infinitely better from a boat, or if you are shore bound, at night.
Just to put a further downer on things, you might find you struggle during the autumn, even down along the Cape, as mid September usually sees the beginning of the striper migration, and you would then have to look to Rhode Island, or Long Island, for the best of the sport with Stripers and Albies.
I have fished the 1st week of October off of Montauk for a few years now, and in all honesty most (But NOT all) years you can't call it fishing, for the only way you are not going to catch a fish, is to not cast your fly in the water or stay well clear of the blitz's


...Great for a few days, but then you look to do other things like, fish deep to try and get some big mommas, or cut the bend off of poppers or crease flies and start ripping them back to see who can get the most hits in one cast!! .
I can absolutely assure you, unfortunate though it is, the fishing is infinitely better over there than off of our coast, and here are a few shots of blitzes taken over the past 5 years or so to perhaps whet your appetite for your next trip over....If time and travel distance constraints allow, you really should give either of these areas a try out.
