Super El Niño to Shape Winter 2026/2027 Weather Patterns
US · Published Aug 27, 2026
The upcoming winter season of 2026/2027 is expected to be heavily influenced by a strong Super El Niño event, according to seasonal forecasts (Severe Weather Europe, 2026).
This phenomenon is driving a split-flow jet stream pattern across North America and Europe, with milder conditions anticipated in northern regions and an active storm track in the southern United States.

Impact & Risks

The Super El Niño is expected to bring significant weather impacts, including above-average rainfall and snowfall in the southern United States, which could lead to flooding in vulnerable areas. Northern regions, including the Pacific Northwest and parts of Canada, may experience drier and milder conditions, potentially affecting water resources and winter sports. In Europe, the dominant westerly flow may result in widespread snowfall deficits at lower elevations, impacting ski resorts and winter tourism. The Polar Vortex may also weaken mid-winter, increasing the likelihood of cold air outbreaks in the central and eastern United States.
