NOAA Puts 69% Odds on a Record El Nino, Not the 81% Some Reports Suggest

NOAA's Climate Prediction Center put out an updated forecast this week, and the headline number is 69%. That's the chance, per the agency, that the El Nino now sitting in the tropical Pacific becomes the strongest ever recorded going back to 1950, with the October-December window as the likely peak.

That represents a significant jump in confidence. NOAA physical scientist Michelle L'Heureux told ABC News the agency now sees a greater than 90% chance of a 'very strong' El Nino, calling it 'the highest chance to date' and saying it reflects growing confidence in what could be 'a potentially historic El Nino event.'

NOAA does not use the word 'super' in its official classifications. The agency's tiers are weak, moderate, strong and very strong. The World Meteorological Organization said flatly in a recent statement that 'the term "super" is not part of standardized operational classifications,' according to ABC News. That hasn't stopped the word from showing up in headline after headline, including from Fox Weather and FOX 5 DC, both of which ran with 'super El Nino' language pulled from informal usage among some meteorologists rather than from NOAA itself.

The 81% Number Versus the 69% Number

Newsweek's report cites an 81% chance of a very strong El Nino developing October through December. ABC News, Fox Weather and FOX 5 DC all cite 69% as the chance the event becomes the strongest on record. These are two different statistics measuring two different things: one is the odds of hitting the 'very strong' category, the other is the odds of setting an all-time record. Conflating them muddies what NOAA is actually saying. The clearest, most consistent number across sources for the record-breaking claim is 69%.

NOAA's Oceanic Nino Index, which tracks sea-surface temperature anomalies in the equatorial Pacific, already has this event ranked as the second-strongest on record for this point in the calendar year, trailing only 1997, according to ABC News. The agency estimates a 97% chance the pattern persists into early spring 2027.

What This Actually Means on the Ground

Johnna Infanti, a meteorologist with NOAA's Climate Prediction Center, told Newsweek the agency is forecasting above-normal precipitation this fall and winter across much of the southern U.S., with the highest confidence over the Gulf States and parts of the Southeast into the Mid-Atlantic. Translation: wetter winter likely for Texas, Louisiana, Florida, the Carolinas. Northern-tier states should expect a better chance of warmer-than-average conditions.

On hurricanes, El Nino cuts both ways depending on which ocean you're in. Fox Weather's Bryan Norcross noted the pattern strengthens the subtropical jet stream, which shears apart developing storms in the Atlantic Basin. That's good news for the Gulf Coast and East Coast this hurricane season if it holds. But that same warm water and low wind shear flips the script in the Pacific, turning it into what Fox Weather described as "a hyper-fueled engine for major hurricanes and monster typhoons." That's bad news for Hawaii, the Philippines, and anyone in typhoon alleys.

NOAA was careful to caveat all of this. The Climate Prediction Center said in its outlook that "even the strongest El Nino events do not lead to the typical impact everywhere, but stronger events can more significantly tilt the odds in favor of expected outcomes." In plain English: a big El Nino raises the odds, it doesn't guarantee a specific outcome in your backyard.

The 1877 Comparison Is a Stretch

FOX 5 DC's piece reached back to the El Nino of 1877, tying it to the Great Famine in India, droughts in Brazil and China, and the Great Flood of 1877 in the Washington D.C. area, with global death tolls estimated at 30 to 60 million. That's real history, but it comes with a massive asterisk FOX 5 DC itself acknowledges: "data limitations from that era introduce some uncertainty." Reanalysis of 19th-century ocean data is nowhere near as reliable as satellite-era readings, and those historic famines were driven as much by colonial-era crop mismanagement and export policy as by weather. Leaning on a 149-year-old, data-poor event to frame 2026 forecasts risks scaring people with a comparison NOAA itself never makes in its official statements.

What Happens Next

NOAA's Climate Prediction Center is expected to issue updated monthly outlooks through the fall as the event approaches its projected October-December peak. The real test comes when actual sea-surface temperature readings either confirm or fall short of the current 69% probability. Until then, treat the record-breaking talk as a forecast, not a fact on the ground.
