Is there a designated swimming area?

You also have to check water quality even before wading. Don't ever go in bay or river/estuary water with any broken skin. Check online.

There's an area protected by a jetty where its safe to swim, it extends out about 20 - 25 yards from shore, but you gotta take caution of the wildlife

Their website says No Swimming

You can wade, but not swim, a.k.a. don't go past the breakers.

Swimming is not allowed at this beach

I believe the signs say you can wade in the water but not swim.

Nope, not even lifeguards
