Never swim alone.Many drownings involve single swimmers.When you swim with someone else,if one of you has a problem,the other may be able to get help,including signaling for assistance from others.
Don't fight the current.The facts show that some 80% of rescues by lifeguards at ocean beaches are caused by currents.These currents are formed by surf and gravity,because once surf pushes water up the slope of a beach,gravity pulls it back.This can create concentrated rivers of water moving offshore.If you are caught in a rip current,don't fight it by trying to swim directly to shore.Instead,swim parallel to shore until you feel the current relax,then swim to shore.Most rip currents are narrow and a short swim parallel to shore will help bring you to safety.
