If I understand correctly, a "wet" suit keeps its wearer warm by allowing a layer of water between the wet suit and the wearer's skin. This layer is then warmed by the wearer's own body heat. The effect seems to be good only above a certain temperature range.
Math Problem: John puts on a rubber onesie, seals it off at the wrists, neck and ankles, fills the interior with water, and then stands outside in -10°C weather. Assuming that John's initial body temperature is 37°C, how long before John's bum freezes and falls off?
This is why I would say No - unless Maybe the person/suit was wet and the temperature was above freezing. Then maybe.
Otherwise a dry suit would be way better as you can layer up warm clothing underneath it as insulation. Drysuits are waterproof so you stay dry. (I own one, it's just super old and the replaced cuffs have also worn out.. might buy a new suit come Spring.)
But overall I would Not choose a wet suit to stay warm in freezing temperatures UNLESS I was going to be underwater, then maybe a thick Winter wetsuit would be Ok. Scuba diving is more of a Fall & Winter activity here, because the water is clearer with higher visibility w/o Summer Sun growing algae blooms. Water temperatures in the ocean aren't much colder in the Winter than Summer, especially deep down.. and neither is there much change in light - it's dark. So, people dive in the Winter as well as at night sometimes. And they can do it in a good Winter wetsuit instead of a drysuit - just depends how hot someone's body runs, too. My older brother is pretty warm-blooded and can dive in a wetsuit whereas skinny minnie people with no bodyfat may all opt for drysuits for cold water.
But I would not choose a wetsuit to try to keep warm above the surface in freezing temperatures - maybe as a last resort it might be better than being naked to wear a wetsuit and try to stay dry vs get wet, but it most certainly wouldn't be my first choice.
