El Niño’s Dreaded ‘Kelvin Wave’ Is About to Hit California
Southern California communities such as Malibu, Long Beach, and San Clemente are watching their beaches disappear. In recent years, rising sea levels have swallowed huge chunks of the coastline, threatening waterfront homes. Now, an El Niño-driven phenomenon is expected to make this situation even worse.

Southern California communities such as Malibu, Long Beach, and San Clemente are watching their beaches disappear. In recent years, rising sea levels have swallowed huge chunks of the coastline, threatening waterfront homes. Now, an El Niño-driven phenomenon is expected to make this situation even worse. During El Niño, winds that normally blow east to west along the equator weaken and periodically reverse, creating westerly wind bursts that set off oceanic Kelvin waves. These massive, slow-moving pulses of warm water travel from the western Pacific Ocean east across the equator until they reach Central and South America, at which point they travel north as “coastal trapped waves” along North America’s Pacific coast. That’s exactly what’s happening now.
