Wetsuit thickness for 40 F water?

[LucasG]

I have moved to Argentina from South Texas where I used to have a 3/2 for Winter surfing and I'm looking for a wetsuit now that will keep me warm on 40 F (10 C) water. Any recommendations? I might be looking at a front zipper to avoid those little streams of water getting into the suit in the back. I also need the booties, gloves and hat.

For Spring and Fall (12ºC) wetsuit 4/3 and booties
in Winter i don't surf ^-^ (7-9ºC) but at least 4/3, booties, gloves, hood

In colder water, wear a thicker wet suit to prevent chill and hypothermia. The chart below gives average recommendations for wet suit thickness for water temperatures.

The ranges overlap depending on individual body heat and comfort; some divers may be more comfortable in a lighter suit, while others may appreciate a thicker neoprene.
