Rip currents form when waves break near the shoreline, piling up water between the breaking waves and the beach. One of the ways this water returns to sea is to form a rip current, a narrow stream of water moving swiftly away from shore, often perpendicular to the shoreline.

How often do rips occur?

According to NOAA, over a 10-year average, rip currents cause 46 deaths annually in the United States, and 64 people died in rip currents in 2013. However, the United States Lifesaving Association "estimates that the annual number of deaths due to rip currents on our nation's beaches exceeds 100."

Are rip currents seasonal?

How far out do rips take you?

"That's why no one bit of advice we give you can guarantee your safety. "Rips have been known to take people 400 metres offshore, whereas some have only taken them a few metres, and some of them have circulated back into the surf break and they've been able to get in."

What to do if you're caught in a rip?

What conditions bring about rip currents?

When waves travel from deep to shallow water, they break near the shoreline and generate currents. A rip current forms when a narrow, fast-moving section of water travels in an offshore direction.

Where are the worst rip currents?

Hanakapiai Beach, Hawaii - Powerful Rip Currents

• Flash rip. This current can form suddenly and vanish just as fast due to decreasing water levels or increasing wave heights.
• Fixed rip. This funnel is usually formed by the wave pressure breaking in the same spot for a long time, eventually making gaps in sandbars. ...
• Permanent Rip.

Do rip currents affect the bay?

What is the difference between a riptide and an undertow?

Undertow occurs along the entire beach face during times of large breaking waves, whereas rip currents are periodical at distinct locations. Riptides occur at inlets every day.
