Whatever you do here, don't ask me about knots... :-O. Everyone's spot on with their advice (per usual).
Seriously though it sounds like you are catching them, which is fantastic. My typical rule of thumb is by the second week in June, I'm exclusively in the surf. The bite slows down as it gets hotter, and I usually hit the beaches exclusively at night or predawn after July 4th. September fall runs...They used to be insane. That's been slowing down a bit, however, this year is unlike any I've ever seen. The size of the fish...wow. Hoping to have a more traditional Fall run. I used to fish well into October, but the last few years I stop around the last two weeks of September. Welcome to the forum, and don't be a stranger.
