What could the super El Niño warming be doing to Southern California?
Southern California may face coastal flooding and traffic shutdowns due to super El Niño The ongoing super El Niño has warmed the ocean along the California coast, which increased the volume of seawater. This effect, combined with Kelvin waves that lift sea level, led to record high tides in Southern California. These high tides caused coastal inundation, resulting in flooding of streets, homes, and businesses. Officials were forced to shut down traffic on a flooded portion of the Pacific Coast Highway.

How it reaches Southern California
-
King tides have inundated parts of both US coasts, flooding streets and sending seawater into homes and businesses in beach communities in California, Florida, and the Carolinas. These tides were caused by the gravitational pull and alignments of the Earth, moon, and sun, and were exacerbated by additional factors this week.
The full event1independent outlet -
The ongoing super El Niño warmed the ocean along the California coast, leading to an increased volume of seawater. This was compounded by Kelvin waves, which are pulses of warm water that lift the sea level. This combination resulted in record high tides in Southern California, causing streets, homes, and businesses to flood, and forcing traffic shutdowns on the Pacific Coast Highway.

Why it matters
Coastal regions of Southern California are highly susceptible to sea level changes and extreme weather events. The combination of super El Niño warming and King tides creates a powerful mechanism for inundation, threatening infrastructure, property, and daily operations along the Pacific Coast Highway and in seaside communities.
While King tides are not new, the reports indicate that the current event was unusual, with residents noting that the flooding reached a level never seen before. This highlights the compounding risk posed by climate phenomena like El Niño interacting with natural tidal cycles.
