I just couldn't resist Chris! Sorry! :sorry:
Normally, I'm reasonably tolerant to cold as long as I'm IN the water. However on my checkout dives I called the second one early as I was so cold I could no longer control my shivering. Normally underwater I don't shiver at all - I recognized my core-cold by being unable to control my breathing (and buoyancy) to my satisfaction, and difficulty in thinking/absorbing more than one thing at a time (normally multi-tasking isn't that hard for me). When my mental gears turned far enough I came to the conclusion that I was cold - at an unsafe level to continue the dive (since I wasn't going to be getting any warmer underwater)
That's why I found it amusing (although in a sympathetic kind of way) that you were soooooooo cold while I was still remarkably toasty after that first dive.
In all seriousness, being fatigued (and 3 hours' sleep will NOT remedy that) makes a person way too susceptible to cold. You were right to call the second dive - if the wind had been less or from the other direction I still would've let you call it, but I would not have been the first one to say "abort". As it was, with the wind truckin' the way it was, I was ambivalent about the dive - and if you're not sure and eager, it's a sign you might not be perfectly happy with the dive. Once upon a time I was bound and determined to get wet and dived in marginal surface conditions despite that little voice in my head and despite the fact that I aborted from three sites previous to that, as being too rough - (this was a freedive mind you, and it's a different discipline) - and when I finally did the dive I had a positively ROTTEN time. Didn't really enjoy it one bit and climbed out early disgusted with myself.
The point of all this long story:
If it doesn't feel right, it's not.
And any diver can call any dive at any time etc etc.
But that doesn't stop my from poking
(a little) fun at you, at least.
