An undertow occurs everywhere underneath shore-approaching waves, whereas rip currents are localized narrow offshore currents occurring at certain locations along the coast.
Which is stronger a rip current or undertow?
Rip currents are much more dangerous, because they flow on the surface of the water, can be very strong, and can extend some distance from the shore. An undertow can occur when water sinks back downhill into the sea after a wave has carried it uphill onto the beach.
Can undertow pull you under?
Most undertows are not very strong, and the risk of one is most severe for inexperienced swimmers who are standing or swimming near breaking waves. An undertow can pull someone underwater for a few seconds, but if the swimmer remains calm and swims towards the surface, he or she should be OK.
How can I get out of the undertow of a rip current?
Rip currents are often detected in about knee-to-waist high water. They can be difficult to escape by walking back toward shore against the current once you are in chest-deep water.
Can a rip current pull you underwater?
Myth: Rip currents pull you under water.
It can drag you down, but it's not truly treacherous because you won't be held under for long. Just relax and hold your breath, and you'll pop to the surface, often on the back side of the waves breaking near shore.
30 related questions foundHow far out do rip currents take you?
Rip currents are generally no wider than about 15 m (16.4 yards), so you only need to swim a short distance to try and get out of the current. Once out of it, you should be able to stand up and make your way back to shore in the areas where you can see breaking waves.
How do currents pull you under?
Rip currents move along the surface of the water, pulling you straight out into the ocean, but not underneath the water's surface. A rip current may knock you off your feet in shallow water, however, and if you thrash around and get disoriented, you may end up being pulled along the ocean bottom.
In what direction does an undertow flow?
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.
Will a life jacket save you in an undertow?
But you have to dive under the breaking wave crests or you make no progress swimming against the surf. If you wear a life jacket in that situation, it won't let you dive under.
Do life jackets help rip currents?
If you see someone in trouble:
Throw the rip current victim something that floats – a life jacket, a cooler, an inflatable ball.
Can lakes have undercurrents?
There are different types of undercurrents that you may encounter in lakes and in the ocean. Some are slow-moving masses of water that you can feel, but they provide very little resistance to swimming. Faster-moving undercurrents provide more resistance and may be difficult to swim against.
What is an undercurrent in the ocean?
An undercurrent is a type of current which runs below the surface of air or water currents. The direction of an undercurrent is typically opposite that of surface currents, and the strength of the undercurrent varies, depending on the situation and the circumstances.
Is the Gulf Stream a minor ocean current?
The Gulf Stream is a strong ocean current that brings warm water from the Gulf of Mexico into the Atlantic Ocean. It extends all the way up the eastern coast of the United States and Canada, where it starts to turn towards northwest Europe.
Can a rip current bring you back to shore?
A rip current won't pull you underwater. It'll just pull you away from shore. If you feel that you're able to swim, do so parallel to the shore until you're out of the current and then swim back to shore at an angle. If you feel that you can't swim, tread or back float, try to wave and yell for help while floating.
Are rip currents worse at high tide?
Rip tide is a misnomer
Heavy breaking waves can trigger a sudden rip current, but rip currents are most hazardous around low tide, when water is already pulling away from the beach.
How can you spot a rip current from shore?
How to spot a rip current
- Deeper and/or darker water.
- Fewer breaking waves.
- Sandy coloured water extending beyond the surf zone.
- Debris or seaweed.
- Significant water movement.
What is a riptide warning?

How wide is a rip?
A rip current, sometimes incorrectly called a rip tide, is a localized current that flows away from the shoreline toward the ocean, perpendicular or at an acute angle to the shoreline. It usually breaks up not far from shore and is generally not more than 25 meters (80 feet) wide.
