San Clemente commuters relying on Metrolink's Orange County Line face a five-day service suspension next week as anticipated "exceptionally high king tides" are expected to impact rail operations along the beachfront tracks near San Clemente. Metrolink officials announced the temporary suspension will run from Monday, Oct. 26, through Friday, Oct. 30, for trains operating between Laguna Niguel/Mission Viejo and Oceanside. This measure is intended to prevent disruptions for travelers, as high tides could lead to delays and cancellations.
The upcoming king tides are expected to bring ocean water levels 18 to 22 inches above previous projections in Orange County and other parts of Southern California, according to city officials. In preparation, Newport Beach announced Thursday that crews are actively reinforcing protective sand berms and strategically placing sandbags in vulnerable areas. Newport Beach officials also issued a warning to residents in low-lying, waterfront, and other potentially flood-prone areas, strongly urging them to take immediate precautions to safeguard their homes, vehicles, and property. Areas specifically identified as being at risk by city officials on Monday include the Balboa Peninsula and islands within Newport Harbor.
During the service suspension, Orange County Line trains will only operate between Los Angeles Union Station and the Laguna Niguel/Mission Viejo station. Passengers planning to travel south of Laguna Niguel/Mission Viejo during this period will need to seek alternative transportation.
This is not the first time high ocean levels have affected coastal rail service. In September, high tides combined with powerful waves overtopped tracks near San Clemente. This previous incident caused significant erosion and slope damage, which led to a temporary suspension of Metrolink, Amtrak, and freight service while emergency repairs were carried out. The decision by Metrolink officials to suspend service preemptively highlights the vulnerability of the rail line to these natural phenomena.
The series of unusually high tide events is just beginning, with more king tides expected in October, November, December, and extending into the new year. City officials further noted that El Niño conditions are anticipated to contribute to elevated ocean water levels in the coming months, potentially exacerbating the impact of these future tide events on coastal communities and infrastructure like the critical rail line running through San Clemente. Residents and commuters are advised to stay informed about coastal conditions and any further advisories regarding transportation or potential flooding.
