Beware of Square Waves: A Hidden Ocean Danger
Square waves, or cross seas, form when two wave systems collide at right angles, creating a grid-like pattern on the water. While striking to see, they signal dangerous conditions with strong currents and turbulence that can overwhelm swimmers and boats. Experts advise exiting the water immediately if you spot them. Always check local advisories and watch for warning signs like rip currents or sudden water changes to stay safe.
