Rays in San Juan

Hi all,

Seems as though there are quite a few large (up to 5/6 foot wide) rays around and there was about 10 all at once in the beach at Playa San Juan, up and around the swimmers.

Two questions: 1) Are these rays dangerous in these waters?
2) Is this seasonal with the summer?

Thanks in advance.

The rays here are not dangerous for swimmers.

Thanks cressrt

Unless cornered hassled... ;)
