I was there in December and whilst the wind could make the rhib rides "fun" it certainly didn't hamper the diving at all. The house reef is pretty well sheltered and just a woddle in from the changing area.
We are going back in March (hopefully about the 5th). The water should be the same temperature as in December. Maria got away with a 3mm full length and I wore a 5mm/3mm suit. Neither of us were cold during, or after, our dives. Here are a
couple of pictures if you want a look.
