What's the coldest water temp you will wetsuit in??

[Diver-Drex]

My comfort limit is 55 for a wetsuit for dives over 40 minutes and for three or more dives in a day.
Dove dry this past Saturday and switch back to wet on Sunday. Water was 56 with a max depth of 80ffw. I wear a 3mm FJ bottom with a 5mm jacket and a hooded vest. Over 60 and I’ll dive no hood.
I’ll dive wet in the forties for 10 minutes or less then need to get back above the thermocline.

46-48 degrees -but it's a function of time as well.

Absolutely. As well, if you're doing a second dive that alters the picture. I've dived in the mid to high 30sF, but maybe squeezed out 20 minutes on one dive a day only. I did dive once in 33F, but that was I believe for 14 minutes (on the Deep course, in the ocean, in late May).

I've often done a couple of dives in a day--mostly in May/June--where it's been mid 40s and 20 minutes each. Shore dives, so no escaping from a thermocline.
