Newport Beach recently faced record-breaking high tides that sent seawater surging over seawalls and into city streets, inundating homes and businesses. The phenomenon, driven by a combination of El Niño conditions, a full moon, and unusually warm ocean waters, affected several Southern California coastal communities, but Newport Beach felt a particularly strong impact.
On Tuesday, the tide in Newport Beach reached 8.4 feet, significantly higher than the predicted 6.7 feet and the highest the city has ever recorded. This unprecedented surge led to the temporary suspension of the Balboa Island Ferry, which has transported vehicles between Balboa Island and the peninsula for over a century. Bill Sharp, a resident of the Balboa Peninsula for six decades, noted that even past El Niño seasons, where residents occasionally swapped cars for paddleboards, hadn't prepared them for this. He observed, "It’s crazy. We’ve somehow added 2 feet of water to the normal sea level," and added that the city's infrastructure was not designed for an 8.5-foot tide.
Scientists explained that a convergence of factors led to these exceptional tides. A full moon on Monday amplified the high tides, exacerbated by warmer than normal ocean temperatures. These temperatures are influenced by human-caused climate change, an El Niño-fueled Kelvin wave carrying warm equatorial Pacific water, and a marine heat wave ongoing for months, unrelated to El Niño. Scientists indicated this marine heat wave alone contributed an additional 1.25 to 1.8 feet to sea levels beyond typical astronomical movements.
Other Southern California coastal areas also experienced significant flooding. Redondo Beach, Huntington Beach, and Long Beach were among them. In San Pedro, a preliminary high tide of 8.19 feet was recorded on Tuesday morning, setting a new all-time record for that location, having broken its previous record just the day before. This sent water rushing onto the International Boardwalk in Redondo Beach and Marine Stadium in Long Beach.
Newport Beach, specifically the Balboa Peninsula, is particularly vulnerable due to its unique topography. Bill Sharp explained that the Balboa Peninsula is "just pinched in between" the beach and the bay, describing it as "generally it’s just a beautiful thing," but acknowledging that "every so often Mother Nature comes to collect some tax." The city has responded by deploying sandbags, water pumps, sand berms, and drainage canals. Dozens of pump trucks were deployed to manage the overflow, working to keep pace with water seeping through defenses. Newport Beach Councilmember Joe Stapleton stated that "Everything the city has prepared is working," placing responsibility for breaches on "commercial or private residential property." He added that the city had tried to inform residents beforehand about shoring up their seawalls.
Despite clear blue skies and warm weather on Tuesday morning, the Fun Zone on the peninsula was effectively on a "war footing," with a four-foot sand wall and rows of sandbags attempting to block the determined ocean. Henk Wiessner, 60, owner of Fun Zone Boat, witnessed water pouring out of his office door. For him, the flooding threatened his livelihood, as the city's seawall blocked access to his dock. "Five minutes later, it was everywhere," Wiessner recalled from an earlier surge. Mark Vukojevic, the city’s director of utilities, was dispatched to the "Pirate House" near Marcus and 35th streets after reports of flooding. He mentioned that the city had sent volunteers to urge residents to build seawalls, emphasizing that those living directly on the water were the "last and only line of defense." An ordinary property near the "Pirate House" that reportedly failed to build a wall allowed water to flow from its back porch into the street. Vukojevic observed, "I think people underestimate the power of high tides." Tim Hogan, a 78-year-old peninsula resident for 37 years, noted that while the surf was calm and the water entering storm drains wasn't a deluge, he was concerned about what the coming months might bring.
Officials warned that this could mark the beginning of a challenging winter season for coastal communities. El Niño is expected to peak this winter, with even higher tides anticipated around the Thanksgiving, Christmas, and Martin Luther King Jr. Day holidays. The combination of these anticipated higher tides with a strong storm could lead to even more severe flooding. The city has been upgrading segments of its seawalls, many of which were built in the early to mid-1900s and are not designed for current rising tides, though much of the harbor-front property remains vulnerable. Despite the ongoing challenges and uncertainty, resident Bill Sharp conveyed a sense of resilience, stating that while "no one is moving because of this," residents are "keeping our sandbags ready."
