Whale Sharks are supposed to be around in the summer months, from early July through November, but we didn't see any. Of course, they were there the week before! We were told that during the 'Whale Shark season' you can see five or so on a single dive. When we headed out into the blue at the end of the dive it was common to have Hammerhead Sharks on the sands below, pods of Dolphins moving through above us and the Silky Sharks moving in close and circling around us.
