Oct 28, 2023 · It’s an undertow, a powerful current that can quickly turn a fun day at the beach into a dangerous situation. But fear not! In this blog post, we’ll dive deep into the topic of undertows and give you all the information you need to know to stay safe in the water.
In physical oceanography, undertow is the undercurrent that moves offshore while waves approach the shore. Undertow is a natural and universal feature for almost any large body of water; it is a return flow compensating for the onshore-directed average transport of water by the waves in the zone above the wave troughs.
Undertow, a strong seaward bottom current returning the water of broken waves back out to sea. There is in fact no such current in a gross sense, for the overall flow of surface water toward the shore in a surf zone is very small. The water actually thrown up on the shore by breaking waves does.

What’s an Undertow? It’s a type of ocean current that occurs when waves break on the shore and the water recedes back to the ocean. Unlike rip currents, which move away from the shore, an undertow flows back to the sea along the ocean floor.

Rip currents are strong offshore flows and often occur when breaking waves push water up the beach face. This piled-up water must escape back out to the sea as water seeks its own level. Typically, the return flow (backwash) is relatively uniform along the beach, so rip currents aren't present. A rip current can form if there's an area where the wa...
Every day, some 6,000 waves break on a given beach. The broken wave pushes water up the beach, and gravity pulls the water back down the beach as a backwash. When big waves break on the beach, a large uprush and backwash of water and sand are generated; this seaward-flowing water/sand mixture is pulled strongly into the next breaking wave. Beachgoe...
A rip tide - or riptide - is a powerful current caused by the tide pulling water through an inlet along a barrier beach. When there is a falling or ebbing tide, the water flows strongly through an inlet toward the ocean, especially one stabilized by jetties. During slack tide, the water is not moving for a short time until the flooding - or rising ...
An undertow refers to the current that flows beneath the surface of the water when waves are breaking upon the shore. It occurs when the seaward-flowing water and sand mixture, created by the uprush and backwash of big waves, is pulled strongly into the next breaking wave.
