El Niño is a natural phenomenon that causes significant weather changes along the Pacific Coast, leading to warmer and wetter conditions.

El Niño is a climate phenomenon that occurs when sea surface temperatures in the central and eastern Pacific Oceans become unusually warm. This disrupts normal weather patterns, influencing regions along the Pacific Coast of North and South America. During an El Niño event, the Pacific Coast may experience increased rainfall and warmer temperatures than usual, which can lead to flooding, droughts, and wildfires. The phenomenon is part of a larger cycle known as the El Niño-Southern Oscillation (ENSO), which also includes the cooler counterpart, La Niña, which brings different weather effects.
