Great White Shark Diving in Capetown?

[alison boler]

Will have 1 day free in Capetown right at the beginning of April next year and would like to do a dive with Great White Sharks :) Obviously no guarantees anywhere, but any views on whether it is better at this time of the year to go to Dyer Island or False Bay? We will only have 1 day and need to be back in Capetown by 530pm latest.

Thanks

Allie
