A rip tide, or riptide, is a strong offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide.
The differences between rip currents, undertows and rip tides
What Is a Rip Tide? 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 .
