Rip currents move perpendicular to the shore, and are common at most beaches. These are transitory currents, which means they can suddenly appear without warning.

Rip currents form when backwash from surf is forced to travel back into the water through a narrow passage such as a reef or sandbar. They are identified by a stream of foam traveling away from the surf zone.

While rip currents can be too strong to swim against, they are also quite narrow in size. If you become caught by one while trying to swim to shore, the best response is to swim parallel to shore until you exit the current.

Some rip currents can be beneficial. If you are surface swimming to a dive site, a rip current can assist you during your swim and carry you closer to your destination.
