This is really simple spot a rip current.
Unfortunately, it's where it looks easiest and safest to enter the sea.
This is because the rip current is looping around and pulling back OUT.
Hence no waves rolling IN. NEVER ENTER THE SEA HERE.
If you are already in the sea and get caught in a rip current (you'll know because you will suddenly be moved from your location and it will be impossible to swim against it) don't panic. Swim ACROSS, not against the rip current.
For example, rather than trying to swim to shore while being pushed out, swim parallel to the beach and you will be able to get out. Then you can swim ashore. Please educate friends or family visiting the beaches this summer. Stay safe 🙏
