| It really depends exactly how much you feel the cold. I was in Sharm in November last year and dived in a 3mm shortie (3 dives per day) without any problems. My buddy used a 3mm full suit and felt a bit cold (although not badly) when surfacing at the end of the second and third dives each day.
The water temperature at the bottom then was 25-26 degrees according to Suunto.
For October, given that you say that you do feel the cold, I would suggest a 3mm full suit. |
