Last week I was in a decent 5mm suit and was a comfortable temperature on all dives. My wife really feels the cold and was in a 7mm semidry with a sharkskin vest, she was fine in the water but always chilled getting her suit off on deck. The Red Sea was very windy last week. On the boat there was a proper mix of suits everything from 3mm shorties to full suits and hoods. It depends a bit on how long you stay under, all our dives where around 60mins, while others on the boat would do 40 minute dives - due to air not the cold.
