This is the time of the year that most Cape May co. back bay flounder fishermen move on to the Delaware bay or Atlantic ocean summer flounder hot spots like reef 11 and the old grounds. I continue fishing the back bay for flounder all summer, only less frequently after July 15. There is always a couple of keepers lurking around, it just takes 10 times the patients to find one or two keepers in late summer. If you want to fill the cooler with summer flounder head to the upper Delaware bay from number 1 north to Fortqescue, the upper Delaware bay flounder bite continues red hot.
