Rip currents are caused by

differences in density and temperature
breaks or changes in longshore currents
the moon's gravitational pull on earth's water
the force of impact from an external object

Rip currents are caused by breaks or changes in longshore currents.

Waves continually break upon the shore one after the other, they never stop.Water from previous waves runs underneath the waves currently breaking on the shore.
