Super El Niño Expected to Amplify Global Weather Extremes
US · Published Aug 15, 2026
A record-breaking Super El Niño is underway, with Pacific Ocean sea surface temperatures averaging 2.7°C (4.9°F) above normal as of early June 2026, according to the Climate Prediction Center and ClimateBrink.
These temperatures are forecast to peak at nearly 4°C (7°F) above average by November.

Impact & Risks

The Super El Niño is expected to bring significant weather disruptions. In New England, warmer temperatures and increased rainfall could lead to flooding, especially with reduced snowpack and midwinter thaws. California faces heightened risks of flooding, mudslides, and debris flows due to an anticipated increase in atmospheric rivers. The Pacific Northwest may see reduced snowpack and prolonged wildfire seasons, exacerbating water shortages. Globally, Indonesia and Australia could experience severe drought and wildfires, while Peru and Ecuador may face torrential rains and flooding. These extreme weather patterns could also impact agriculture and food supplies worldwide, particularly in regions like South America.
