I agree with everything Sexy2011 said and would add that it makes a difference whether you're swimming where there's a life guard and whether you have someone with you. Even with a lifeguard, on a beach with a lot of people you can be missed, take a friend so there's someone to yell for help if you get into trouble. The best swimmers can have problems in a heavy undertow or if they get cramps.
Never swim alone where's there's no lifeguard.
