Survive Your Very Own Emergency With Nature’s Warnings

If You Spot Square Waves, Get Out The Water

This water pattern doesn’t seem possible at first, but it happens when two wave currents run into each other. One of the wave systems carried on despite the wind changing direction, creating what is called a “cross-sea.”

Even though they look cool from the shore, they can be especially dangerous for surfers, ships, and swimmers. Underneath the surface of these cross-seas is an especially strong current that can drag you out to sea.
