The primary risks include sneaker waves, which can knock people off their feet and drag them into the ocean, and strong rip currents, which can pull swimmers away from shore. These conditions are dangerous even for experienced swimmers. The NWS has emphasized that these hazards can lead to life-threatening situations, especially for those near rocks, jetties, or piers. Federal safety data indicates that rip currents are responsible for over 100 deaths annually in the U.S. and account for more than 80% of beach lifeguard rescues.
