I was out at 4th ave from 3:45pm to 4:30pm and it was barely ridable and I also looked at it at 5:30 am. It sucked then also. Honestly at best maybe knee high.
So it was knee? at least there was something. And just because it's flat in Belmar, Avon, OG, Asbury. Doesn't necessarily mean it's flat in BB. Sounds stupid but I have seen waves there for years when nothing else around is breaking. (4th Ave). that place just works.
As i said before I didn't see it myself so i cannot say what it truly was. But some people's perspective of waves can be way off. I don't doubt him when he said there was something rideable tho.
Shark River Hills is not its own town it is part of Neptune. You live in "THE TUNE" embrace the lifestyle don't hide it.
As for 4th ave its alright up to chest, over that the places stinks. I found that after the reblenishment it holds smaller surf better then other spots but, at size its no good.
