Beach Hazards Statement

Sneaker Waves Possible

A long period, southerly swell is entering our coastal waters. This swell brings a moderate potential for sneaker waves along South and Southwest facing beaches. Sneaker waves are a unique hazard, with many minutes between waves. Pay attention and stay above the high water line and any wet sand during both high and low tides to stay safe. If the ground is wet, water has been there recently. Stay safe and never turn your back on the ocean!
