Riptide redirects here. Riptide may also refer to an American TV series.
A rip current is a strong flow of water returning seaward from the shore. It is also called a "rip tide" or "riptide", or colloquially simply a rip. Rip currents typically flow at 0.5 metres per second (1-2 feet per second), and can be as fast as 2.5 metres/second (8 feet per second). They can occur at any beach with breaking waves, including the world's oceans and large lakes such as the Great Lakes in the United States and Canada. A common misconception is that a rip occurring under the water, instead of on top -- an undertow -- is strong enough to drag people under the water; this is not true.
Such currents can all be extremely dangerous, dragging swimmers away from the beach and leading to death by drowning when they attempt to fight the current and become exhausted. Rip currents cause approximately 100 deaths annually in the United States. About 80% of rescues by surf beach lifeguards are due to rip currents.
Surviving an encounter with a rip current
It is important to never attempt to fight a rip current. One should always swim parallel to the shoreline. If you see a person caught in one, yell at them to do so. This removes the swimmer from the current, which typically occurs most strongly between sandbars. Floating until the current disperses into deeper waters is also another method of surviving such a dangerous incident, but it may leave the swimmer farther out from shore. Rip currents can be deadly for non-swimmers as well. A person standing waist deep in water can be dragged out into deeper waters. If they are unable to swim, and are not wearing a flotation device, drowning is a strong possibility.
Avoiding the shore when surf is rough (such as during high onshorewinds, or when a strong hurricane is far offshore) is an advisable safety measure, as this is when very strong tides or currents are most prevalent. Posted warnings, where available, should always be heeded. Also, check the local newspaper and internet for tide timetables. (Beware, tides can be substantially different at beaches relatively close to each other.) Never go into the water without lifeguard supervision from -2 to +4 hours of low tide--especially at night.
The truth is that the gentle ripples will prevail because the stormy riptides, their beliefs and attitudes are fading away and dying off.
You can see this change in the eyes of the younger instructors and students as they listen to, observe, and put into action the wisdom they learn from the wiser, older, gentler teachers, who display their talents and skills at seminars, trade shows, or wherever these gentle giants are assembled to pass on their knowledge.
Until this is done on a college type level, these titles will float around in the riptides for the amateurs and the unqualified to crown them selves with, and for the public to continue to be led astray.
Riptides at that section of the beach have been especially severe this season because the May storms apparently changed the beach's underwater profile, said Sgt. Cheryl Clancy of the New Hampshire Marine Patrol.
A riptide is a fast current that rushes seaward after in-coming waves pile up on the beach.
He said he can recognize a riptide has formed because the water is foamy and discolored with sediment.
