5mm... too much. We used 5mm suits a lot this summer in the Bahamas, where it's chillier than the rest of the Caribbean. Our teaching groups were SUPPOSED to be assigned 3mm suits, but there was an office snafu.
Anyways, the 5mm were unnecessary, and dealing with the extra buoyancy and surface overheating problems made for a real nightmare. Eventually we ended up chucking all of them in a pile, and most of the students dove with just their swimsuits on. Very rarely did they get cold.
In the winter, most people dive with a 3mm suit, either a shorty or full.
