Ocean water flooded streets Monday morning in Newport Beach at the start of a week of possible record high tides in Southern California.
High tide reached 8.3 feet Monday in the Orange County with a high tide of 8.5 feet expected Tuesday, according to the Newport Beach Police Department. Coastal flooding is a major concern this week, especially along the city’s Balboa Peninsula and other low-lying areas.
Water pumps were activated and sand berms were in place in anticipation of the significant flood threat.
“If you live in a low-lying or waterfront area, please take precautions to protect your home and property,” police said in a statement. “Use sandbags or temporary flood barriers and move your vehicle to higher ground if needed.”
Parking enforcement will be suspected through Wednesday evening, allow residents to move vehicles.
Coastal communities are bracing for another round of high tides that could cause areas to flood, beach erosion and damage infrastructure. Tracey Leong reports for the NBC4 News at 11 p.m. on Saturday, Oct. 24, 2026.
A coastal flooding advisory is in effect through 1 p.m. Thursday in parts of Orange County. A coastal flood advisory also was declared until 1 p.m. Thursday at Los Angeles and Ventura County beaches.
“For the start of the week, out main focus is going to be at the coast with the possibility of record high tides,” said NBCLA forecaster Belen De Leon.
Morning tides ranging from 7.5 to 8 feet are expected along the Los Angeles County coastline. The tides could challenge the record at San Pedro, where a high tide of 7.93 feet was recorded Jan. 10, 2005. Records at that location date to 1924.
Areas of Long Beach, Malibu and Newport Beach have already seen damage to homes from high surf in recent weeks.
Tides are running about 1 to 1.7 feet above astronomical predictions in Orange County and roughly 1 to 1.5 feet above predictions along the Los Angeles County coastline.
Minor coastal flooding is likely in vulnerable low-lying areas, including harbor walkways, beach parking lots, bike paths and normally sandy beaches. More significant flooding and damage are possible in locations with little or no remaining sandy beach or where previous high tides have already caused problems.
The anticipated tides will also disrupt rail service along the Orange County coastline. Metrolink Orange County Line service will be suspended beginning today between the Laguna Niguel/Mission Viejo and Oceanside stations. Trains will originate and terminate at the Laguna Niguel/Mission Viejo Station through Friday.
Away from the beaches, dry and warm weather is expected to continue across Los Angeles and Orange counties through Monday, with mostly clear skies and generally weak winds. A gradual return of onshore winds is expected Tuesday, bringing slightly cooler temperatures and an increasing marine layer along the coast.
Another storm system could reach Southern California late Thursday or Friday. Measurable rain is possible for most, if not all, of the region between Friday and the weekend,
although the timing and rainfall amounts remained uncertain.
