In a quarry, thermoclines 'warn' you as you go deeper, viz. isn't as good as the nicer oceanic settings, there's not current, no long swim out, waves are generally not an issue, and coming up away from a boat or needing to think about deploying an SMB aren't issues. Someone once posted elsewhere that some northern divers can run into trouble at 1st in the tropics because they're unconsciously used to the visual cue of falling light levels to provide feedback about depth, but the viz. may be great way deep in the tropics.
At the risk of inspiring a heckling debate about whether PADI should start offering a 'Salt Water Diver' specialty, there are some differences in diving the ocean. And people vary in their aptitude for retaining & applying some of the info. for judging conditions. I've got the NAUI Master Diver course manual as a general reference, and enjoy it. I've read over the chapter discussing waves, currents and such more than once. But if you hauled me out to a shore, and asked me to point out what was going on, you'd probably get an 'Uhhh…'
I love shore diving Bonaire. But if I were going to hit a place (for shore diving) I didn't already know and haven't been, like Lauderdale by the Sea, I'd want to do some advance research on the site 1st.
Somebody boat diving the ocean for the 1st time, I'd suggest starting with guided dives. It's like the advice sometimes given that if you change your gear, dive the new equipment 1st in a familiar, non-challenging environment. Get 'dialed in' to minimize task loading. Well, a new diver gawking at the reef & oceanic life, in the ocean for the 1st time, trying to navigate by compass and swim into mild current and wondering if the planned turn pressure was a good choice, might get a bit task loaded.
What a person 'should' do is also impacted by thoroughness of training, natural aptitude for the knowledge and skills, and personality of the diver - are you meticulous and disciplined, laid back and not very focused, etc...
