Well most people don`t know what to do and its very easy to get out if you don`t panic
You can sometimes identify a rip current by its foamy and choppy surface. The water in a rip current may be dirty (from the sand being turned up by the current). The water may be colder than the surrounding water. Waves usually do not break as readily in a rip current as in adjacent water.
If caught in a rip current, try to relax. A rip current is not an "undertow" -- it will not pull you under. Do not try to swim against the current as this is very difficult, even for an experienced swimmer. If you can do so, tread water and float. Call or wave for assistance. You can also try to swim parallel to shore until you are out of the current, then swim directly toward shore...
