Mission Beach’s berm was meant to hold. Seawater reached inside a home.

The sand berm was supposed to keep the ocean out. On Monday morning, October 26, 2026, it broke—and seawater crossed the sidewalk and entered Debbilyn Kovalik’s Mission Beach home. San Diego’s response was to reinforce the barrier and deploy pumps. Whether that work kept the next high tide out of the affected properties has not been confirmed. ¹

On October 25, we reported that exceptionally high tides threatened low-lying coastal property. That was a forecast, not a damage report. Monday’s breach supplies a concrete answer to whether the water would reach homes: it reached inside Kovalik’s, and flooded a nearby yard used by Mission Bay Puppy Rescue. The detailed household accounts come from 10News; a dated Desert Sun video description separately identifies Mission Beach flooding on October 26. ^{1 78}

The distinction matters for another earlier assessment. NBC 7 San Diego reported on October 25 that no damage had been reported in the county as of Sunday morning. That account described conditions before Monday’s breach; it is not a conflicting account of what happened afterward. ^{9 1}

Kovalik learned from neighbors that the berm had broken and water was rushing toward her home. When 10News reporter Yasmeen Ludy walked inside with her, water sloshed underfoot. Kovalik said Mission Beach had flooded before, but the water had never previously entered her house. “It came up to here, and right in the sliding glass door, there’s water all the way through,” she said. ¹

She expected trouble behind the baseboards. “All the drywall behind the baseboards. Yeah, there’s going to be some damage,” Kovalik told 10News. That was her expectation of concealed damage, not a completed assessment. The extent and repair cost remain unknown. Her immediate concern was preventing another intrusion. ¹

A couple of houses away, Jackie Nipper said her yard filled within seconds. She described a tiny gap that allowed water through. Nipper runs Mission Bay Puppy Rescue, making the flooded outdoor space more than a residential yard: puppies play there, and prospective adopters come to meet them. ¹

The reporting establishes flooding of that yard—not flooding inside Nipper’s home, injury to puppies or an evacuation of the animals. The loss of a usable outdoor space is consequential without assuming an animal casualty or an adoption disrupted. “This is their front yard. This is where they play during the day,” Nipper said. ¹

Before the tide receded, residents waded through knee-deep water to enter and leave homes. Camille LeFever, visiting from Arizona, encountered the floodwater returning from a morning beach walk. She told 10News the muck reached her knees and that she showered immediately afterward. These accounts describe difficult access, not a measured, uniform flood depth throughout the neighborhood. ¹

Christopher McGinnis said he had lived in Mission Beach for 30 years and had never seen flooding like it. “We had the berms and everything, so I’m thinking, no big deal,” he said. His surprise captures the neighborhood’s problem: a protective barrier had encouraged confidence, but the water found a way through. ¹

McGinnis estimated the water was about a foot above prediction. The National Weather Service’s broader coastal observations described high tides running 1.5 to 1.7 feet above astronomical predictions—the levels expected from tidal cycles. His estimate and the warning-area measurements are not interchangeable, and neither figure measures the depth inside Kovalik’s home. ^{1 3}

10News, citing the weather service, reported Monday morning’s La Jolla tide as nearly eight feet. La Jolla is a separate location farther north along the coast. A tide elevation is measured relative to a reference level; it does not mean eight feet of water covered Mission Beach floors or sidewalks. The exact peak, observation time and reference datum behind that rounded report have not been independently verified. ¹

“Nearly eight feet” also cannot establish a record. The Los Angeles Times cited an earlier La Jolla benchmark of 7.81 feet on November 25, 2015. Determining whether Monday exceeded it requires an exact observation on a comparable datum, not a rounded description. The earlier question of whether La Jolla actually topped eight feet therefore remains open. ^{7 1}

10News identified warmer ocean temperatures and a Kelvin wave—a broad ocean disturbance that can raise coastal sea levels—as contributors to the unusually elevated water during this El Niño season. Its local outlook called for morning tides above seven feet on Tuesday, October 27, and Wednesday, October 28. Those were expected peaks, not final measurements. No verified later flood at Kovalik’s home or Nipper’s yard has been established here. ¹

The city said crews were reinforcing the breached berm and using pumps, according to 10News. Residents argued the barrier should have been higher. That complaint deserves an answer, but it is not an engineering finding: no verified dimensions, design threshold or post-breach assessment establishes why this berm failed or what height would have prevented the flooding. ¹

The warning’s duration also needs a clear distinction between competing accounts. On October 27, KTLA Los Angeles reported that the coastal flood warning for Orange and San Diego counties ran through Tuesday at 1 p.m. The National Weather Service’s October 27 warning text instead specified Thursday, October 29, at 1 p.m. PDT. A later bulletin issued Tuesday at 12:53 p.m. PDT retained that Thursday end. The dated weather service text supports the Thursday schedule, not KTLA’s Tuesday end. ^{2 3 132 136}

An earlier Tuesday alert’s metadata separately listed an expiration of 2:30 p.m. PDT that day, even though its warning text continued through Thursday. That metadata time should not replace the announced hazard end. The later dated bulletin establishes the schedule as of its issuance; we have not independently confirmed the warning’s live status. Nor does a scheduled end promise that an individual property will then be safe. ^{3 132 136}

The warning identified further risks to low-lying homes, businesses and some critical infrastructure, along with possible road closures and shoreline erosion. Those are potential additional consequences, not a verified inventory of Mission Beach damage. Officials urged people to avoid flooded areas and use caution near the water. Drivers should not go around barricades or enter water of unknown depth. ^{3 11}

For the affected households, an announced repair is only the beginning of an answer. Monday showed that water could pass the barrier and reach a living space. What residents still need to know is whether the revised protection can withstand the next high tide.
