San Diego Prepares for Potential “Super” El Niño Event

San Diego, CA, September 12, 2026 —

San Diego is making preparations for a significant El Niño event anticipated for the upcoming fall and winter seasons. Officials are anticipating a potentially record-breaking “Super” El Niño, though the precise volume of rainfall remains uncertain and contingent upon evolving weather patterns.

The forecast indicates that this El Niño is expected to bring about elevated high tides and substantial ocean swells. These conditions are projected to heighten the risk of coastal flooding and erosion along San Diego’s shoreline.

In response to these potential threats, the city has initiated measures to mitigate flood risks. Sand berms are currently being installed along the city’s beaches and within Mission Bay. These structures are intended to serve as a protective barrier against the anticipated rise in sea levels and wave action.

Specific details regarding the projected intensity of the rainfall or the precise timelines for the El Niño’s full impact were not detailed in the information available. The duration and exact geographical extent of the anticipated coastal flooding and erosion are also subject to the developing meteorological conditions. The city’s proactive installation of sand berms represents an effort to enhance coastal resilience ahead of the predicted weather phenomena.
