SoCal Coastal Weather Alert

By on September 26, 2026

As of Saturday afternoon, September 26, 2026, the main concern is ocean swell arriving during high tides not a direct hurricane landfall in Southern California. Ocean Swells from Polo and Hurricane Odalys could bring dangerous surf, rip currents, beach erosion and flooding in low-lying coastal areas.

The greatest overlap of surf and high tides is expected Monday and Tuesday, September 28–29. The size of the waves and the extent of flooding remain uncertain.

Area What forecasters are watching
Long Beach, Malibu, Avalon,Orange County and Santa Barbara The National Weather Service identifies these as particular flooding concerns. South-facing beaches could see seawater cross low walkways, parking lots and roads; erosion and localized structure damage are possible. Avalon is especially exposed to Polo’s southeasterly swell. forecast.weather.gov
Orange County beaches Polo’s swell is expected to affect Orange County, especially northern Orange County. South and southwest-facing beaches face the greatest risk when surf meets the morning high tides. forecast.weather.gov
San Diego County beaches Many beaches are more sheltered from Polo’s particular swell direction, but other swell and high tides still create a risk of tidal overflow, erosion and strong rip currents. forecast.weather.gov

Forecasters expect roughly 4–7-foot surf on south-facing beaches in the Los Angeles forecast area Sunday through Tuesday, with considerable uncertainty. For Orange and San Diego counties, the posted Beach Hazards Statement forecasts 3–5-foot surf, with sets to 6 feet, and morning tides approaching 7 feet Monday through Wednesday. Those tide figures describe the predicted water level at the tide gauge; they are not a forecast of seven feet of flooding on streets. forecast.weather.gov

Preparations are already underway in Long Beach. Crews have built sand berms to protect shoreline homes and businesses following damage from Hurricane Marie earlier this month. Residents in flood-prone blocks should follow city alerts, move vehicles and belongings away from exposed low areas, and have a plan if officials direct them to leave. Beachgoers should stay out of the water during hazardous surf and keep clear of breaking waves near seawalls and walkways. ABC7 Los Angeles

The NWS Los Angeles forecast discussion and NWS San Diego alerts are the best places to check for changes. Los Angeles forecasters said Saturday morning that they were considering whether to upgrade their Beach Hazards Statement to a Coastal Flood Advisory.
