Did another dive today,9/16, and the vis is back to being terrible. It had to be the rough surf from the hurricanes off the coast. Visibilty was about 5' and there is a really abnormally high tide. If you're snorkeling with 5' vis and an really high tide you can't see much unless you constantly hold your breath and go all the way to the bottom. Only problem with that is if you do too repidly you can hyperventilate. I know I've done it in the past.
