Many beachgoers enjoying the waters off Newport Beach on the July Fourth holiday were in for a rude awakening. Lifeguards rescued 350 people Friday after the surf turned dangerous. In one instance, multiple people were rescued from a “monster rip current,” according to social media posts from Newport Beach Lifeguards.

Drone footage from Newport Beach, California shows a massive rip that forced hundreds of rescues. A police boat was required for some of the rescues.
