A potential Super El Niño is putting the US winter weather forecast for 2026 into sharper focus after researchers at Columbia Climate School said the tropical Pacific is displaying several early warning signs associated with a stronger El Niño event later this year.

While no Super El Niño has been officially declared, scientists say unusually warm ocean temperatures beneath the equatorial Pacific deserve close attention because they could influence weather patterns across much of the United States during the upcoming autumn and winter.
