Nice wind, attack fish, man-o-war, sharks and other sea pests?

Wow man. I would have completely panicked. I know now in the Winter time there is like a huge migration of sharks heading North. Do you happen to know when that migration finishes? I would assume sometime in the summer, like May, when the water is warmer. Be careful man, last year or the year before (I don't remember exactly) a kitesurfer was killed by a school of sharks after falling into the water in West Palm Beach. I believe it was during the time of the shark migration.
