The City of Seal Beach is implementing measures to prepare its residents and infrastructure for the upcoming El Niño season, which experts indicate could be among the strongest on record. Discussions at the Sept. 14 City Council meeting included warnings of potential coastal flooding from high tides, with preparedness actions already underway and expected to extend into March.
Climate Scientist Dr. Daniel Swain informed the City Council at the Sept. 14 meeting that there is a 95% to 99% likelihood that this El Niño event will become one of the strongest on record. Dr. Swain noted, "We are in rare, if not unprecedented, territory here." El Niño is a natural climate pattern in the Pacific, occurring every two to seven years, that results in warmer ocean waters. While the peak intensity of this event is anticipated between October and December, Dr. Swain stated that California will likely experience the strongest impacts from December through March of next year.
Experts expect a high risk of coastal flooding and significant rainfall during this period. Dr. Swain indicated that at least some parts of the California coast could experience their worst coastal inundations on record, potentially rivaling severe El Niño years of 1997-98 and 1982-83. Southern California, in particular, is forecast to see disruptions in marine ecosystems, increased coastal humidity, and temporarily higher sea levels, possibly up to two feet, worsening through fall and winter. For Seal Beach, a worst-case scenario could affect significant residential areas, including Naples and Sunset Beach. Waves are projected to be more energetic and prone to causing damage, and heavy rainfall could lead to dangerous stormwater runoff containing untreated waste.
In response to these forecasts, Seal Beach Police Sergeant Brian Gray detailed the city's preparedness strategy at the Sept. 14 City Council meeting. The city has accelerated construction of its annual 14-foot winter sand berm, which Senior Engineer David Spitz explained is crucial for reducing the force of waves, though some flooding and ponding on the boardwalk may still occur. The city is also staging pumps and barricades, and public updates are being issued as conditions evolve. Sergeant Gray confirmed that city staff continuously monitor National Weather Service forecasts, tide, surf, and field conditions, with police, public works, marine safety, city management, and OCFA coordinating efforts before and during significant events.
Beyond physical infrastructure, the city is focusing on resident education. Sergeant Gray emphasized the importance of preparing residents and directed attention to the police department’s emergency preparedness website. During the rainy season, Seal Beach city officials plan to distribute free sandbags at Arbor Park, Fire Stations 44 and 48, and Marina Park. Participants in the Seal Beach Neighbor 4 Neighbor program, a police department initiative for community assistance, will receive a 25% discount on emergency preparedness supplies. Additionally, the Seal Beach Police Department will host a flood mitigation workshop on October 6 to train residents in practical flood prevention techniques.
These preparations come as other Orange County coastal cities have already addressed recent high tide impacts. Following high tides and surf from Hurricane Marie, Laguna Beach and Dana Point declared states of emergency to facilitate funding for beach erosion repairs. Most recently, the San Clemente City Council declared a local emergency and approved emergency sand placement at North Beach after high tides damaged private property and the city pier. Dr. Swain concluded his remarks by emphasizing the timeliness of Seal Beach's preparations, stating, "The time to prepare is now."
