Unusually high surf and flooding over the weekend of September 12–13, 2026, caused multiple incidents along the Southern California coastline. A seawall in Long Beach gave way under the force of the waves, a sinkhole opened at a Malibu celebrity residence, and homes in Dana Point suffered damage from the surge.
In Long Beach, the strong surf broke through a seawall that protects the shoreline. The breach allowed water to surge onto the adjacent area, prompting immediate concern for nearby infrastructure. Local officials reported the damage but did not provide further details on the extent of repairs needed.
Further north, the same wave action produced a sinkhole at a well-known Malibu home. The property, identified as belonging to a celebrity, experienced a sudden collapse of ground beneath part of the residence as the water undermined the soil. The incident was observed by passersby and quickly reported to emergency responders.
In Dana Point, the elevated surf levels caused damage to residential structures. Several homes along the coast reported water intrusion and structural impacts resulting from the high waves. Residents were advised to take precautions as the flooding persisted through the weekend.
The series of events reflects the broader pattern of unusually strong surf and flooding that affected the Southern California coast during those two days. While the specific causes of the heightened wave activity have not been detailed, the incidents underscore the vulnerability of coastal infrastructure to extreme ocean conditions. Authorities continue to assess the damage and coordinate repairs across the affected communities.
