The Atlantic side of the Cape is mainly dived in the summer months of October to February. The visibility is usually in the 10 meter range and which, after a South Easter blows, can go up to 25m! Average temperature for these dives is typically in the region of 12-13°C, but can drop to the 9-10°C range. (Definitely better on the warmer days) A good quality 5 or 7mm wetsuit will do the job, but grabbing a semi-dry or dry suit can only improve your dives. However if you do decide to brave the chill the Atlantic offers some phenomenal diving!
