smolderinglime:isurus, yes, Monterey is supposed to be a really cool place to dive. But it sure wasn't on my 4 dives (due to weather mostly). That's ok, hopefully when I hook up with the university, I'll see more in Monterey.
Ayisha, I'm a tall female but not very wide and the wetsuits they had at the rental place fit me verticially, but were too roomy...so, I'll probably have to get mine custom fitted or find a company that makes taller wetsuits. We wore 7mm two piece wetsuits. Our instructor wore a drysuit and said it was just better. And, yes, I was wearing gloves and a hood. Neoprene socks sound like a good idea, because my feet were super cold!
My congrats also - but you have had a pretty ugly start to diving. It should be enjoyable at the worst, or at least one would hope so.
Having that poor fitting suit was most likely far more of an issue than just being cold, they can hold a lot of water. My name in this forum refers to a night dive a long time ago, where we came upon a school of giant puffer fish, all sleeping, but swimming together into the current. I brilliantly decided to wake one and take it back to the boat. It filled itself up to the size of a beach ball, and I actually tried to pick it up- providing years of jokes for all that were there.
You have gotten some excellent advice here, but I don't understand two aspects of your first ocean dive:
1. It sounds like there was no predive walk through that covered what to do when things go wrong? Anyone diving from the shore in So Ca is going to see varying waves, and some will knock anyone down. Not all entries are with the BC inflated, not all involve crawling, if you fall.
2. What happened to the post dive review? You should have had the chance to tell how you felt and what you though was going on. This is for your benefit and the instructor.
If you have to tell your instuctor, there is something very wrong.
Without a plan, almost every new diver will want to standup and head to the shore (it is dryer there)
I hope you will stick around to see the great aspects of diving.
