The Old Farmer’s Almanac has released its Winter 2026-2027 forecast, highlighting the potential impact of a strengthening Super El Niño on weather patterns across the United States.
According to the Almanac, ocean temperatures in the tropical Pacific are rising, which could disrupt the jet stream and lead to significant winter storms.

Impact & Risks

The strengthening Super El Niño is expected to bring significant weather risks across the U.S. Southern regions, including California, the Southwest, and the Gulf Coast, may face heavy rainfall, flooding, and severe weather, with Florida particularly vulnerable to tornadoes. Northern areas, such as the West, northern Plains, and Great Lakes, could experience sudden cold snaps, snow squalls, and volatile temperature swings. Businesses in energy and transportation sectors may face operational disruptions, including travel delays, infrastructure impacts, and fluctuating demand. The polar vortex could further exacerbate risks by introducing extreme cold to areas expecting near-normal temperatures.
