Dec 16, 2012. Cage Diving with Great White Sharks off the Coast of South Africa. This was a birthday gift from my daughter Shevaun to me on my visit to Cape Town. We were cage diving with Great White Shark Adventures, about 2 hours east of Cape Town. As in the video, we did manage to see a couple of small great whites which was a thrill. The ideal time to see them would have been around October as they migrate through following the seals. Seeing the sharks up close was still exciting, but be warned, the water temps are 13-14C and it was quite chilly even with the supplied wet suits. After half and hour in the water, it was a releif to get out and warm up again. This was filmed with my GoPro2 and my Nikon P7000. Enjoy!
