Coastal North Bay including Point Reyes National Seashore, San Francisco Peninsula Coast, Northern Monterey Bay and Southern Monterey Bay and Big Sur Coast as well as San Francisco County are under an updated high surf warning which was issued by the National Weather Service on Friday at 9:16 p.m. The warning is in effect until Saturday at 3 a.m.
The NWS San Francisco CA said, “Dangerously large breaking waves of 20 to 30 feet and up to 45 feet for the highest waves on west facing beaches. Non-west facing beaches will see dangerously large breaking waves of 15 to 20 feet and up to 30 feet for the highest waves.”
“Breaking waves can sweep people off jetties and docks, and into dangerous seas. Life-threatening swimming conditions and significant beach erosion can be expected. Sudden immersion in cold water can result in cold water shock even for the most experienced swimmers. Cold water shock can result in dramatic changes in breathing, heart rate and blood pressure, greatly increasing the risk of drowning in rough open waters,” according to the NWS. “Everyone should remain out of the water due to life-threatening surf conditions. Stay off of jetties, piers, and other waterside infrastructure.”
