California Coastal Flooding and High Surf: What You Need to Know (2026)

California's coastal regions are bracing for another challenging week as the threat of high surf and coastal flooding persists until Wednesday, according to weather officials. While the waves are expected to be less intense than last week's historic swell, the potential for dangerous conditions remains, particularly for beachgoers and coastal residents.

One of the most alarming developments was the record-breaking ocean water level in San Francisco, which reached 1.83 feet above normal high tide on Saturday. This level is unprecedented for the summer months and is typically only seen during the winter storms of November to March. The National Weather Service's records, dating back to 1898, confirm this unusual surge.

The City of Newport Beach is taking proactive measures to mitigate the risks. City employees have been distributing sandbags to residents to protect their properties from potential flooding. Additionally, the city has issued a warning to beachgoers, urging them not to park in low-lying areas and to drive slowly through flooded zones to avoid creating wakes that could exacerbate flooding.

The beaches facing south or southwest have been identified as the most vulnerable to dangerous rip currents and sneaker waves over the past week. This information is crucial for beachgoers, as it highlights the specific areas where they are most at risk. The recent tragic incidents, including the rescue attempt in Santa Cruz and the recovery of a 5-year-old's body in Laguna Beach, underscore the very real dangers posed by high surf and rip currents.

To stay safe, officials recommend that beachgoers avoid rocks and jetties during high surf and remain vigilant. If caught in a rip current, it is advised not to panic but to swim along the shoreline until free of the current's pull. In cases of emergency, treading water and calling for help is a recommended course of action.

As the week progresses, residents and visitors alike must remain cautious and informed. The combination of high tides, strong currents, and potential flooding creates a complex and potentially dangerous situation. By staying updated on weather alerts and following safety guidelines, everyone can contribute to minimizing the risks associated with California's dynamic and sometimes treacherous coastline.
