Sharks get a bad rap, but they're not the number one danger in these waters. Rip currents are. And you don't have to be in deep water to be at risk. Someone standing waist deep could be pulled offshore before they even realize what's happening. Here's how to spot one. From the shoreline, look for a flat, calm-looking gap between breaking waves. That calmness is not a safe spot. That's where the water is moving away fast from the shore. You might also see discolored water, foam, or seaweed being pulled offshore. If you get caught in one, do not swim against it. You will lose. These currents can move faster than an Olympic swimmer. Stay calm, float, and swim parallel to the shore till you're out of it. Then angle back in. If you can't do that, wave your arms and yell. Teach your family about this and check the rip current safety before hitting the beach.
