Super El Niño Brings Wetter and Cooler Weather to U.S. South and Southwest
US · Published Sep 14, 2026
According to the Sierra Club, a Super El Niño event has officially begun, marked by a significant shift in atmospheric and oceanic patterns.
Normally, trade winds push warm surface water from South America toward Asia, but during El Niño, these winds weaken, causing warm water to accumulate in the Central and Eastern Pacific.

Impact & Risks

The Super El Niño is expected to have widespread effects, particularly in the southern and southwestern United States, where increased rainfall and cooler temperatures are anticipated. While this may alleviate drought conditions in some areas, it could also lead to flooding and other weather-related disruptions. Globally, El Niño events are known to influence weather patterns, potentially causing droughts in some regions and excessive rainfall in others, which could impact agriculture, water resources, and ecosystems.
