Newport Beach coastal flooding pushed city leaders to declare a local emergency on Friday, October 9, 2026, after seawater spilled onto streets and properties on the Balboa Peninsula. According to NBC Los Angeles, the declaration helps the city secure extra resources while crews respond to the flooding and elevated surf through the weekend.
Newport Beach coastal flooding sent ocean water across Balboa Peninsula streets on Friday, and the city declared a local emergency. Tides are running well above normal, and officials say Sunday carries the highest flood risk. Crews are rebuilding sand berms, and free sandbags are available. Residents are urged to stay out of flooded streets.
How the Newport Beach Coastal Flooding Unfolded
The trouble started with Friday morning’s high tide. Voice of OC reported that high surf kept pushing seawater into Balboa Peninsula streets, and the city declared its emergency shortly after noon.
The water was deeper than forecasters had expected. A city utilities director told ABC7 that the morning tide arrived about 20 inches above its prediction, the Los Angeles Times reported. Video showed flooding across roughly 10 blocks, with water knee-high in places.
Fire Chief Jeff Boyles warned that parts of Balboa Boulevard were covered by nearly 2 feet of water. He told people not to drive, walk or bike through it. By afternoon the water had drained away, CBS Los Angeles said, leaving businesses and homeowners to start cleaning up.
What City Crews Are Doing to Hold Back the Water
Work continued overnight. Officials said at an evening news conference that crews would keep rebuilding sand berms through the weekend, and City Manager Seimone Jurjis said the aim is to strengthen as many weak spots as possible before the next high tide.
Police said crews were also pumping water off streets. City News Service reported that Newport Beach runs 86 tidal valves to stop ocean water from backing up through storm drains, plus 18 pumps for standing water near the harbor.
The city says its measures cannot remove every risk. Temporary street closures and parking restrictions may follow if conditions worsen.
Why the Tides Are Running So High
City Councilmember Erik Weigand pointed to Kelvin waves, which he described as a tidal push rather than a typical swell. He said tides were projected to run about 20 inches above predicted highs. A Kelvin wave is a warm-water anomaly that travels from near the equator and can lift sea levels for extended periods.
Officials expect every high tide to run above normal, especially on south-facing beaches such as parts of Newport Beach, Long Beach, Dana Point and Laguna Beach.
The exact cause is still being sorted out. Some outlets tie the surf to distant Tropical Storm Rachel, while Patch noted that the flooding and erosion have not been conclusively linked to the Kelvin wave.
Residents and Businesses Start Cleaning Up
The Newport Beach coastal flooding hit close to home. One musician waded through chest-high water in her garage on West Balboa Boulevard and managed to save only her keyboard. A tour company owner spent the afternoon rinsing saltwater off beach cruisers after the street filled up like a lake that morning.
Several neighbors said they moved quickly to block doorways with sandbags. The extent of the damage was not immediately known, according to City News Service.
Where to Get Sandbags
- Filled sandbags are free at the City Corporation Yard, 592 Superior Ave., which stays open overnight.
- Peninsula residents can also pick them up at Marina Park.
- Lifeguard vehicles on the peninsula carry sandbags.
- Empty bags are at fire stations while supplies last.
Safety Steps From Officials
The city asked drivers to avoid flooded streets, choose alternate routes and follow directions from public safety crews. Officials also encouraged residents to clear gutters, move cars out of flood-prone areas and sign up for Newport Notified alerts. Orange County also launched an El Niño information website at ocgov.com/el-nino.
What to Watch Through the Weekend
Saturday morning’s high tide was expected to run about 3 inches above Friday’s, the city manager said. Sunday looks harder still. The National Weather Service expects tides 1 to 1.5 feet above astronomical charts, and the fire chief said Sunday morning would likely be worse because of a larger swell.
The coastal flood warning ends at 3 p.m. Sunday, but a coastal flooding advisory stays in place through Tuesday. For anyone living near the water, Newport Beach coastal flooding remains a live concern until those alerts expire.
