Hi - I will be heading out to Lembeh for a quick dive trip soon. I am wondering if I will need to get a new 5mm wetsuit (only have an 3mm full suit). I read on a couple of diving websites that the Strait water is cold in the summer. Wondering what do most people wear during that time of the year (3mm + hood or 5mm)? I am a petite woman so the rental suits at the dive shops usually doesn't fit me well (too many loose pockets of space so lots of water movement = cold!) I usually dive in 83-85F carribbean water and feels nice and toasty in my 3mm full suit. Thanks!
