"Today might not be the best day to go surfing, tidepooling, or frolicking along the shoreline. The National Weather Service has issued a warning to Northern Californians of potentially deadly sneaker waves reaching 13 to 18 feet in height along the coast until at least 10 p.m. Sunday. These waves get their name because they occur spontaneously during seemingly normal surf, when an offshore swell and coastal winds meet at the perfect intersection."
"The NWS warns that sneaker waves can run significantly farther up the beach than typical waves, and that accompanying rip currents can appear, especially around piers, jetties, and inlets. If that wasn't enough to disincentivize would-be beachgoers, a buoy off the San Francisco coast reports a water temperature of 57 degrees Fahrenheit cold enough to make a person lose dexterity within 15 minutes and to kill them within one to six hours, according to the University of Sea Kayaking."
The National Weather Service issued a warning to Northern Californians of potentially deadly sneaker waves reaching 13 to 18 feet along the coast until at least 10 p.m. Sunday. Sneaker waves occur when offshore swells and coastal winds align. Westward-facing beaches such as Ocean Beach, areas of Santa Cruz County, and peninsula towns like Pacifica face higher risk. Sneaker waves can run farther up the beach than typical waves, and rip currents can appear, especially around piers, jetties, and inlets. A buoy off San Francisco reports 57°F water, cold enough to impair dexterity within 15 minutes and to be fatal within one to six hours.
