Last year we split our dives up between morning and afternoon dives, all dives were great, the wind does have a bit of a tendancy to kick up in the afternoon, especially the very southern dive sites can get a little choppy but still very diveable, depending on your experiance of course. The simple cure to this to do dive sites in the more northern section of the park, shorter boat ride too!
I had a couple of very nice shore dives off Caribe Blu in May, sure there were sand deposits and the sea fans weren't as abundant as they used to be, but that's just first impressions.
In fact, at first glance it looked pretty barron, but then I started looking around, we found tons of eels, arrow crabs, blenny's, slipper lobsters, yellow sting rays, cuddle fish, scorpion fish, barracuda (what's the big one named? Molly?), anyway, saw her.
It really was a very good dive for someone who likes to poke around in the coral and rocks like I do.
HEY ANN! how did you get in at airplane flats, we stopped by Martin's shop in May and they wouldn't let us get in saying there was no diving there because of too much debris.
