A rip current (or just rip) is a specific type of water current that can occur near beaches where waves break. A rip is a strong, localized, and narrow current of water that moves directly away from the shore by cutting through the lines of breaking waves, like a river flowing out to sea.
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.
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.

Ocean current, a current in the ocean Rip current, a kind of water current; Current (hydrology), currents in rivers and streams; Convection current, flow caused by unstable density variation due to temperature differences; Current (mathematics), geometrical current in differential topology
The Ventura County sheriff suggested that Rivera and Dorsey likely found themselves caught in a rip current – these can be common in the area of the lake they were in, especially during the afternoon – and struggled to get back to the boat, which was found unanchored and so may have drifted from where they entered the water. He concluded ...
In contrast to undertow, rip currents are responsible for the great majority of drownings close to beaches. When a swimmer enters a rip current, it starts to carry them offshore. The swimmer can exit the rip current by swimming at right angles to the flow, parallel to the shore, or by simply treading water or floating until the rip releases them.
This current as part of a baroclinically unstable system meanders and creates eddies (in much the same way as a meandering river forms an oxbow lake). These types of mesoscale eddies have been observed in many major ocean currents, including the Gulf Stream , the Agulhas Current , the Kuroshio Current , and the Antarctic Circumpolar Current ...
In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry. In tidal zones, the current and streams may reverse on the flood tide before resuming on the ebb tide.
