Record-breaking tides flood Newport Beach and Southern California coast

Summary

Exceptionally high tides caused by El Niño, a marine heat wave, a full moon, and a Kelvin wave produced record-breaking coastal flooding across Southern California in late October 2026. Newport Beach experienced an 8.3 to 8.4-foot high tide, the highest ever recorded in the city, with seawater surging over seawalls and flooding low-lying areas; streets near 38th Street and River Avenue disappeared beneath roughly a foot of water. San Pedro recorded a preliminary tide level of 8.02 feet, surpassing the previous 2005 record of 7.93 feet. Flooding also affected other coastal communities including Long Beach, Huntington Beach, Redondo Beach, and Malibu. Authorities deployed sandbags, water pumps, sand berms, and drainage canals to mitigate damage. The Balboa Island Ferry suspended operations, and Metrolink halted rail service between Oceanside and Laguna Niguel through October 30. Coastal flood warnings remained in effect for Orange County through Thursday, with advisories for Los Angeles and Ventura counties. High tides were expected to persist through the week, with additional severe conditions anticipated as El Niño reached its peak in winter.
