Classic example of a Riptide (undertow). Turn your sound up, ocean is loud. Save a life and watch

Please put up with the soft spoken narration, there were kids sleeping in the room and the ocean noise drowned out most of the voice. Panama City Beach FL

After a little research, what you're seeing is a riptide or some call it an undertow.
As you can see, the beach is closed, two red flags.
The water is coming IN where it is white and washing into the center where the water is a darker color. It's coming in from both sides and dumping into the middle. then it's going back out in the middle. The incoming waves are deceiving (over the dark area), but that's why some call it undertow. The water under the incoming waves is moving outward with great strength. You can see the white foam moving out in the middle. From this angle (in the air), it's easy to see, but on the beach, most of it looks the same. It's good that the beach-goers are there, as they give the immensity of the phenomenon some scale. See the white bubbles coming up beyond the break of the surf. This is where a person "might"resurface after being taken out by the undertow or riptide as some would call it. Be careful out there people. This is dangerous.
