Rip Currents

 

What is a rip current ?

Most waves are formed by wind on the water. Sea waves usually result from storms, often hundreds of miles from shore. Waves are not all equal in size. Sometimes a group of larger waves comes ashore one after another. This is known as a "set" of waves.  When waves break, water is pushed up the slope of the shore. Gravity pulls this water back toward the sea. If it converges in a narrow, river-like current moving away from shore, it forms what is known as a rip current.

      Rip currents can be 50 feet to 50 yards or more wide. They can flow to a point just past the breaking surf (the surfline) or hundreds of yards offshore. Some 80% of rescues by lifeguards at America's surf beaches are due to persons being caught in rip currents. Rip currents may pull continuously, but they can suddenly appear or intensify after a set of waves, or when there is a breach in an offshore sandbar

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.

What to do if you get caught in a rip current

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.
