“Sneaker waves are disproportionately large waves which surge unexpectedly up the beach without warning,” the U.S. Coast Guard website states. “They are characterized by insignificant heights within period groups of small waves, giving the appearance of light sea conditions. The sudden rush of water will immerse the dry shore and send large logs rolling, becoming dangerous projectiles. Other hazards include being swept out to sea and immersion into cold water. Sneaker waves are the deadliest natural hazard on the West Coast.”
