1) Yes, quiets down progressively thru these coming months. [The odd looking dive boats look that way for a purposeful design utility. Center moon wells, four entries, three ladders, just for such conditions]
2) Never, except rare occasions at night. There are many times that people venture out and i just shake my head, but…
Even if it’s pure crap, crazy cross current, bad viz, all that…i have had magical dives inside of the reef, no deeper than 6’. Get tired? Stand up.
CCV has very few “rules”.
3) It? As in the Front Yard? Yes. Just keep one thing in mind: you have the only real viable shore dive on Roatan. No one else, anywhere else- even has the option. This shore ingress/egress access is used many times daily, guessing 100-125x per day. Night divers are a part of that guess, usually 5-20 each night.
The Front Yard is a study in hydrology that is pretty simple if you gave me an hour to explain it and keep buying me Salva Vidas. Suffice to say: never skip a drop off dive where you scuba in from the boat. It’s never any advanced challenge coming in.
If the waves are crashing over CCV Wall (on the L), that water’s going to affect your outbound paddle.
No matter how bad things manage to get near shore, once you get to the Prince Albert wreck, the vertical walls will be fine.
Talk with DMs, but your best source will be guests with 15 or 50 prior trips. Well before dinner, they’ve decided if they’re night diving or drinking beer. Divers are a friendly group, esp at CCV where sharing their familiarity with the terrain is a big thing.
