SOUTHERN CALIFORNIA FLOODS — 114 Properties Damaged as Ocean Water Invades Streets

Описание: Record-breaking high tides flooded streets, homes, businesses, and coastal roads across California on October 27–29, 2026. From Sunset Beach and Newport Beach in Orange County to Mission Bay in San Diego, ocean water pushed into neighborhoods even without a major rainstorm.

In Huntington Beach, ABC7 reported 114 damaged properties as residents assessed the aftermath. Pacific Coast Highway was temporarily closed, while record tide readings showed that the flooding was part of a much larger coastal event.

CALIFORNIA STREETS FLOODED BY HISTORIC TIDES

In Sunset Beach, a low-lying Huntington Beach community, seawater covered roads and reached residential properties and businesses.

A section of Pacific Coast Highway between Warner Avenue and Anderson Street faced temporary closures during the high-tide periods.

Residents placed sandbags and protective barriers around homes, but some reported seawater entering their properties.

At Newport Beach, officials measured an 8.3-foot high tide on October 26, followed by a record 8.4-foot tide on October 27.

The Balboa Peninsula and Newport Harbor were particularly vulnerable.

The city declared a local emergency, activated its Emergency Operations Center, and deployed pumps, sand berms, sandbags, and other flood-control equipment.

SAN DIEGO AND MISSION BAY FACE FLOODING

Farther south, rising water reached streets around Pacific Beach and Mission Bay.

San Diego's tide gauge registered 8.52 feet on October 27, while La Jolla recorded a preliminary all-time high of 7.98 feet.

These figures measure water levels relative to tidal reference points, not floodwater depth inside homes or across roads.

The measurements demonstrate the extraordinary conditions along Southern California's coastline.

WHY DID CALIFORNIA'S OCEAN LEVELS RISE?

The October 25 full moon contributed to higher astronomical tides, but other influences made the flooding more serious.

Forecasters identified unusually warm Pacific Ocean waters, strengthening El Niño conditions, and a coastal Kelvin wave that helped elevate sea levels.

On October 29, the National Weather Service reported observed water levels in Orange and San Diego counties approximately 1.3–1.6 feet above astronomical predictions.

When ocean levels are already unusually high, additional tidal increases can push seawater across curbs, harbor edges, and coastal flood barriers.

That explains why neighborhoods experienced flooding without a major rainstorm directly overhead.

COASTAL FLOOD WARNINGS AND ADVISORIES

On October 29, the National Weather Service allowed its Coastal Flood Warning for Orange and San Diego counties to expire.

However, a Coastal Flood Advisory remained scheduled through 2 p.m. Friday, October 30.

Forecasters warned that minor coastal flooding could continue around roads, parking lots, parks, and vulnerable waterfront areas.

Farther north, coastal advisories around San Francisco Bay, San Pablo Bay, and Monterey Bay were extended through Sunday, November 1. Some Pacific-facing coastal areas remained covered through Saturday, October 31.

These were location-specific forecasts, not confirmation that every community would experience flooding.
