Answer
Rip currents are concentrated channels of water flowing away from shore and are a leading surf hazard; “undertow” is a looser popular term that does not replace rip-current safety guidance. If caught in a rip, swim parallel to shore until free, then angle back in. Ask Beach Patrol about same-day conditions.
