The effects of this super El Niño could be severe for San Diego's coastline, particularly in low-lying areas such as Imperial Beach, Coronado, Ocean Beach, La Jolla Shores, and Del Mar. Warmer ocean temperatures may disrupt marine ecosystems and fisheries, while higher sea levels combined with strong storms and large waves could exacerbate coastal erosion and flooding. Vulnerable infrastructure, including buildings, roads, and drainage systems, is at heightened risk. High tides around Thanksgiving, Christmas Eve, and late January are expected to peak at approximately 7 feet, increasing the potential for significant coastal impacts if storms coincide with these events. While the strength of this El Niño surpasses the 1982-83 event, its exact impact on the region remains uncertain (inewsource, 2026).
