Morning dives with them lots of times...I'm kind of a regular....but what the other posters said. Also, if you look at the GCS meetup site for the dive, they list who's going. Most folks are pretty conscientious about cancelling on the board if they change their mind. I tend to check it before I leave the house on days with iffy conditions.
If you're talking about tomorrow, I'm on a boat dive elsewhere, but beach conditions are looking pretty good for all weekend and they're doing two morning beach dives at two locations...an 8am in lbts and a 9 am in Dania (two groups of divers). Given the forecast (flat to 1' surf) I doubt there's much chance of either of those dives cancelling.
If you're looking for an awesome beach dive (long swim but cool dive), they're going out to the Copenhagen wreck on Sunday morning.
