Summary

Exceptionally high tides struck the Southern California coast from October 26-27, 2026, causing coastal flooding across Newport Beach, Long Beach, and other communities in Los Angeles and Orange counties. Tides reached record or near-record levels, with San Pedro recording 8.02 feet (surpassing the 2005 record of 7.93 feet) and Newport Beach experiencing 8.3-foot tides. Floodwaters inundated low-lying areas, with streets near 38th Street and River Avenue in Newport Beach disappearing beneath roughly a foot of water. Authorities deployed sandbags, water pumps, and sand berms to protect vulnerable neighborhoods, and parking enforcement was halted to allow residents to relocate vehicles. Metrolink suspended rail operations between Oceanside and Laguna Niguel through October 30. Coastal flood warnings remained in effect for Orange County through Thursday afternoon, with coastal flood advisories for Los Angeles, Ventura, and San Luis Obispo counties. The flooding was attributed to a rare combination of factors including El Niño, a marine heat wave, and an astronomical alignment occurring once every 20 years, with ocean levels running approximately 22 inches above predicted levels.
