Rip currents

A relatively small-scale surf-zone current moving away from the beach. Rip currents form as waves disperse along the beach causing water to become trapped between the beach and a sandbar or other underwater feature. The water converges into a narrow, river-like channel moving away from the shore at high speed. A rip current consists of three parts: the feeder current flowing parallel to the shore inside the breakers; the neck, where the feeder currents converge and flow through the breakers in a narrow band or "rip"; and the head, where the current widens and slackens outside the breaker line in deeper water.

A channel of churning, choppy water
An area having a notable difference in water color
A line of foam, seaweed, or debris moving steadily seaward
A break in the incoming wave pattern

These areas may hold fish, they are deeper holes and should be searched at lower tides. The shore line changes frequently depending on swell size, swell direction, tidal flow and time of year. Fish will generally hold in the deeper sections, for these are feeding zones and safe zones. You will want to determine the direction of a trough, whether it angle away from the beach, parallel to it or directly out to sea. This will determine the best way to approach and fish them.
