San Francisco, CA – Sneaker waves could surge up the beaches of Northern California starting Friday evening, posing a serious threat to swimmers, walkers, and anglers along the coast. A Beach Hazards Statement is now in effect from Friday through Saturday evening, covering the San Francisco Peninsula and surrounding counties.
According to the National Weather Service, a long-period northwesterly swell will increase the risk of strong rip currents and unexpected wave run-ups. Areas near jetties, rocks, and inlets—including popular stretches along Highway 1 and the Big Sur Coast—are especially vulnerable. Officials urge beachgoers to remain out of the water and avoid climbing on wet rocks or walking near the surf zone.
While conditions inland will feel ideal for fall, the coastal zone tells a different story. San Francisco and nearby areas will stay dry, with sunny skies and highs in the low-to-mid 70s through the weekend. Morning fog remains minimal, and winds will stay light—ideal for pumpkin patches, park strolls, or Halloween setup.
Saturday and Sunday will be warm and bright citywide, but the surf hazard along the Pacific will remain in effect until Saturday evening. Lifeguards advise extreme caution, as sneaker waves often strike without warning and can drag people into dangerous waters.

- Saturday: Sunny, high near 75°F, beach hazard warning in effect
