Southern California Braces for Record-Breaking Tides and Flooding 2026

Southern California is bracing for record-breaking tides and potential flooding this week, as coastal communities from San Diego to Los Angeles prepare for significant impacts. The National Weather Service (NWS) has warned of unusually high tides that could close roads, inundate homes and businesses, and threaten critical infrastructure.

Record-Breaking Tides Hit Southern California

By Monday morning, the NWS office in Los Angeles reported that record tides were already occurring. Preliminary observations from the San Pedro tide gauge showed a water level of 8.02 feet, the highest since data collection began in November 1923. This surpasses previous records and underscores the severity of the current tidal event.

The NWS warned that significant coastal flooding is expected in San Diego and Orange counties through Thursday. To the north, a wide swath of coastline from San Luis Obispo County to Los Angeles County could see minor to moderate coastal flooding, with tides as high as 8 feet.

Communities Mobilize to Protect Residents and Property

In response to the threat, Newport Beach in Orange County declared a local emergency more than a week before the exceptionally high tides were forecast to arrive. City staff are deploying across the area to inspect infrastructure, reinforce beach berms, and install sandbags and other equipment. The city is also providing free sandbags to residents and advising them to take precautions.

Other coastal communities are similarly preparing. The NWS office in San Diego issued a statement urging people to avoid beaches during high tides, stay farther back from the ocean than usual, stay off rock walls and jetties, and ensure flood-prone property is protected.

Why These Tides Are Exceptionally High

The record tides are the result of a combination of astronomical and meteorological factors. High tides occur when the gravitational pull of the moon and sun align, but this week's tides are amplified by other conditions. While the article does not specify the exact causes, such extreme tides can be influenced by sea level rise, storm surges, and other climatic factors.

Regardless of the cause, the impacts are clear: low-lying coastal areas are at risk of flooding, and residents and visitors need to take the warnings seriously.

What You Can Do to Stay Safe

If you live in or are visiting coastal Southern California, follow these safety tips:

• Avoid beaches during high tides and stay farther back from the water than usual, as waves will run much farther up the beach.
• Stay off rock walls and jetties, which can be dangerous during high surf.
• Protect flood-prone property by using sandbags and other barriers, and move valuables to higher ground.
• Monitor local weather forecasts and heed evacuation orders if issued.
• Never drive through flooded roads—turn around, don't drown.
