Rip currents are the proximate cause of 80% of rescues carried out by beach lifeguards. [10] Rip currents typically flow at about 0.5 m/s (1.6 ft/s). They can be as fast as 2.5 m/s (8.2 ft/s), which is faster than any human can swim. Most rip currents are fairly narrow, and even the widest rip currents are not very wide.
Rip currents are caused by the interaction of waves, tides, and underwater topography. When waves break unevenly, the water flows back out to sea in concentrated channels. Undertow vs Riptide
Rip currents can flow quickly, are unpredictable, and come about from what happens to waves as they interact with the shape of the sea bed. In contrast, a rip tide is caused by tidal movements, as opposed to wave action, and is a predictable rise and fall of the water level.

Rip currents can occur in any weather, so assume that they’re present at a surf beach and take the time to identify any of the indicators. What to do if you're caught in a rip current.
A rip current statement is a warning statement issued by the National Weather Service of the United States when there is a high threat of rip currents due to weather and ocean conditions. [ 1 ] The statement usually contains some detail about when and roughly where the rip currents are most likely to be forming.
Hurricane Lee is expected to cause dangerous rip currents and huge waves along the U.S. East Coast. Here’s what to know about rip current safety.
Rip currents are forceful currents of water flowing away from shore at surf beaches and usually extend from near the shoreline, through the surf zone and past the line of breaking waves, the ...
The surf zone can contain dangerous rip currents: strong local currents which flow offshore and pose a threat to swimmers. Rip-current outlooks use the following set of qualifications: Low-risk rip currents : Wind and/or wave conditions are not expected to support the development of rip currents; however, rip currents can sometimes occur ...
