Precautionary actions
Inexperienced swimmers should remain out of the water due to dangerous surf conditions.
Swim near a lifeguard. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.
