I went in June a few years ago. From the south side of the bay so it might have been different, but the stripers were not in the river then, I think they said it was the fall. But we did a charter trip and trolled for bluefish and had a lot of action and good fights. Trolling for bull reds is also supposed to be good then, but in our case unfortunately the captain was not prepared. We found a school on side scan, vectored over them on the troll with the too small bluefish rods, got four simultaneous knockdowns but broke off all of them. By the time they re-rigged it was over. But oh well it was still a good trip and the bay is awesome and there will definitely be something available.
Have a great trip.
