3/2 is fine for me in anything above 68 or so. You'll be fine. Weather is a bit unpredictable that time of year though.
I'm just in the Miami International Airport waiting my fly back to my country. I've arrived last Saturday morning for a Telecom Conference starting on Monday. I had reserved a place for a dive trip on Sunday morning.
All diving activities were suspended this week owing to hurricane IDA. Strong winds and high seas.
You cannot imagine how upset I was. I've been waiting this trip and the diving reward for months. Nothing could be done. No one is to blame, please, do not misunderstand me, but it was a real pitty.
