Here in Ontario going in in 40 degree water is pretty normal and I use a 7mm. The coldest I have gone in I saw 39 degrees and it was chilling but I was about 30 minutes. I know some that will still use a 7mm down to mid 30’s. When it starts getting chilly we usualy bring a thermos of warm/hot water to pour in the suite before jumping in and this helps with the shock of hitting the cold water and slows the cooling down.
