Super El Niño 2026: Forecast, Impacts, and Uncertainties
7/13/2026, 11:58:12 PM
Core Event – A Historic Climate Pattern Takes Shape
The Climate Prediction Center (CPC) announced a 97 % chance that the 2026 El Niño will be “strong” or “very strong” through the three-month period ending December, with an 81 % chance it will be “very strong.” The same CPC briefing gave a 97 % chance the pattern will persist through the upcoming winter and into spring 2027. Meteorologists label such intensity “super” El Niño.
Background & Context – Formation and Past California Encounters
El Niño arises when east-to-west trade winds weaken, allowing a downwelling Kelvin wave to push warm water eastward. “Basically, it’s a wave in the ocean that will bring warm water from the western Pacific to the central and eastern Pacific.” — Jon Gottschalck, Climate Prediction Center operational prediction branch chief. Historically, “very strong” events in 1982-83 and 1997-98 delivered more than double the usual rainfall to downtown Los Angeles, while the 2015-16 episode produced record coastal erosion. The most recent “strong” El Niño of 2023-24 yielded 22.15 inches of rain in downtown L.A.—155 % of the 14.25-inch average—triggering hundreds of landslides.
Data & Statistics – Numbers Shaping the Outlook
- CPC probability: 97 % strong/very strong, 81 % very strong.
- AccuWeather projects a 70 % likelihood of reaching “very strong” by winter.
- Global sea-surface temperature in June set a record for this time of year (July 1 confirmation).
- 2024 water year: downtown L.A. received 22.15 inches of rain; the three-day period was the second-rainiest since 1877.
- Coastal California experienced “record coastal erosion” during the 2015-16 super El Niño.
Expected Impacts – Weather Extremes, Flooding, and Travel Disruptions
Southern California can expect above-average rainfall, raising flash-flood and landslide risk. “There’s really a wide array of impacts that can come that vary significantly from place to place across the globe.” — Ariel Cohen, National Weather Service meteorologist, Oxnard. A marine heat wave already affecting the Southern California coast is expected to intensify. The FOX Forecast Center warns that the “highly energized, subtropical jet stream” will lock across the southern U.S., likely causing “a high chance of travel delays due to the severe weather.”
Official Statements & Responses – Agency Perspectives
The World Meteorological Organization notes that El Niño “typically increases global temperatures,” while the Copernicus Climate Change Service reported that “current conditions could indicate the beginning of a new phase… we are likely to see more temperature records fall in the coming months.”
Criticism & Opposition – Limits of Predictability
CPC cautions that even the strongest El Niño events “do not lead to the typical impact everywhere,” meaning regional outcomes remain uncertain.
On-the-Ground Reports – Early Signs of Trouble
In Baldwin Vista, a 2024 landslide left mud piled in a homeowner’s backyard, illustrating the immediate hazards already materializing.
Conflicting Reports & Gaps – Inconsistent Rainfall Patterns
The 2015-16 super El Niño doubled downtown L.A.’s rainfall, yet the 2023-24 strong event produced only half the typical amount, highlighting the difficulty of projecting precise precipitation totals.
Verbatim Quotes – Voices from Scientists and Forecasters
- “Basically, it’s a wave in the ocean that will bring warm water from the western Pacific to the central and eastern Pacific.” — Jon Gottschalck, Climate Prediction Center
- “There’s really a wide array of impacts that can come that vary significantly from place to place across the globe.” — Ariel Cohen, National Weather Service
- “We know that temperatures are warming in the long term, linked to human-caused climate change, and El Niño acts to boost those temperatures temporarily.” — Zachary Labe, Climate Central
- “Current conditions could indicate the beginning of a new phase, leading, once more, to uncharted territory… we are likely to see more temperature records fall in the coming months.” — Carlo Buontempo, Copernicus Climate Change Service
- “I think it’s fair to say that, depending on [the] model, the forecasts are close to unprecedented.” — Michael Tippett, Columbia University atmospheric scientist
What’s Next – Monitoring the Evolving Threat
The CPC will issue weekly updates through winter, with the peak expected in early winter 2026-27. Travelers are advised to monitor FOX Weather alerts and NOAA flood warnings as the pattern intensifies.
