At least at the beach near the Disney resort I've never seen any jet skis or wind surfers. There are cats and sailfish for rent nearby though. Wind surfing would be great- jet skis would have to watch carefully for low tide sand bars.
At low tide, you can easily wade out 50-100 yards from the beach (nice white sand) and still be comfortable with the ocean depth.
Boogie boards and body surfing are great in the usual waves. if there are off-shore storms, the waves will be larger.
We just returned to our villa from the beach. Ocean temps are 84 right now!
