Every few years the Pacific Ocean near the equator warms up, and suddenly half the country is talking about El Niño. This year the talk is louder than usual, and for good reason: NOAA now gives the 2026 event a very high chance of becoming very strong, and forecasts a real chance that it could become the strongest since records began in 1950. That is a forecast, not a done deal. So what does that mean for the snow shovel, the rain gauge and the power bill in your part of the country? Let me walk you through it, without the hype.
Short answer: very likely very strong, and possibly historically strong. In its September 10, 2026 update, NOAA's Climate Prediction Center gave a greater than 90% chance of a very strong El Niño this fall and winter, and forecast a 75% chance of an event that could be historically strong, stronger than any since 1950, during October to December (NOAA CPC). For U.S. winter weather, that tilts the odds toward a wetter South and California and a milder North. Tilts the odds, not guarantees: every El Niño winter still has its own surprises.

Where the 2026 El Niño Stands Right Now
NOAA has an El Niño Advisory in effect. That is the official way of saying: El Niño is here and expected to continue. In its September update, the Climate Prediction Center wrote that El Niño "strengthened over the past month, with sea surface temperature anomalies exceeding +3.0°C in the eastern equatorial Pacific" (NOAA CPC ENSO discussion). In plain English: parts of the ocean there are more than 5°F warmer than normal. That is a lot of extra heat sitting right under the jet stream's nose.
Figures from NOAA's September 2026 ENSO discussion and strength probabilities (NOAA CPC strength table). The next ENSO update is due on October 8, 2026, and we will update this page after it.
How Strong Is "Very Strong"? The Scale Explained
NOAA measures El Niño with an index called RONI (Relative Oceanic Niño Index). Since February 2026 it has replaced the older ONI. RONI compares the key area of the Pacific with the rest of the tropical oceans, so a warming planet does not make every El Niño look stronger than it really is (NOAA CPC). The number is the temperature difference in °C, averaged over three months:
The famous "super" El Niños of 1982-83, 1997-98 and 2015-16 were all in the very strong class. "Super" is a nickname, not an official NOAA category. If you like the history, our page on the strongest El Niño events in history lines them all up, and what causes El Niño explains the ocean and wind behind it.
What It Could Mean for U.S. Winter Weather
Here is the key idea. During El Niño the Pacific jet stream, the fast river of air that steers storms, tends to stretch out and run across the southern United States. The polar jet tends to stay farther north. The result is a fairly familiar pattern, and NOAA's September outlook calls it "a classic El Niño signature" (NOAA CPC seasonal outlook):
| Region | What the odds favor this winter | Read more |
|---|---|---|
| California | Wetter than normal, 50 to 60% chance near the coast in winter. Storms, atmospheric rivers, flooding risk. | El Niño winter in California |
| Southwest, Gulf Coast, Southeast | Wetter than normal, up to 70 to 80% chance over southern Georgia and northern Florida. | Track rainfall at home |
| Colorado and the Rockies | NOAA's broad wet signal covers the southern and central U.S., while the interior Northwest leans slightly dry. Temperatures in the southern Rockies are a coin flip. | El Niño and western snowpack |
| Northern tier and Midwest | Milder than normal, with a slight dry tilt around the Great Lakes. Cold snaps still happen. | El Niño in the Midwest |
| Interior Northwest | Slightly drier and warmer than normal. | Super El Niño 2026 tracker |
NOAA climate scientists note that the Gulf Coast is the most consistent signal in strong El Niño winters, that the Ohio and Tennessee Valleys often run drier, and that California's wet signal gets more reliable the stronger the event is (NOAA Climate.gov).
Why a Strong El Niño Is Not a Guarantee
I wish El Niño came with a money-back guarantee. It does not. NOAA itself says that with an event this big, the chance of typical El Niño impacts is larger, "though not guaranteed". Two reminders keep me humble:
So think of El Niño as loaded dice, not a script. Your local forecast and warnings still decide what you do on any given day.
The Side Effect Everyone Noticed: A Quiet Hurricane Season
El Niño also adds strong upper-level winds over the tropical Atlantic, which tear young storms apart. That is a big reason why the 2026 Atlantic season reached late September without a single hurricane, something not seen since 1914. The full story is in why the 2026 Atlantic hurricane season has had no hurricanes, and the mechanism in how El Niño affects the Atlantic hurricane season.
What to Do at Home This Winter
You cannot change El Niño, but you can make sure it does not catch you off guard. Here is my short list, from cheapest to most fun:
Get the warnings
A NOAA weather radio with S.A.M.E. wakes you for a flood or winter storm warning, even when the phone is on silent. Program it with our S.A.M.E. code steps.
Measure your own rain
In a wet El Niño winter, knowing how fast rain is falling at your house tells you more than a regional total. See how much rain is too much.
Plan for outages
Storms bring down trees and power lines. A crank radio and a charged power bank keep you informed. More in weather radio for power outages.

2026 El Niño FAQ
How strong will the 2026 El Niño get?
NOAA's September 2026 update gives a greater than 90% chance of a very strong El Niño this fall and winter, and forecasts a 75% chance of an event during October to December that could be historically strong, stronger than any El Niño since 1950. That is a forecast: whether 2026 actually becomes historic will only be known once the season's data is in.
Is the 2026 El Niño a "super El Niño"?
"Super El Niño" is a nickname, not an official category. NOAA's top official classes are very strong (2.0°C or more) and, for this event, historic (2.5°C or more on the RONI index). NOAA's forecast gives 2026 a good chance to reach those classes, but that is not yet confirmed.
What does El Niño mean for winter in the United States?
It tilts the odds toward a wetter southern U.S. and California, and a milder, often drier northern U.S. and Ohio Valley. These are odds, not guarantees: storms, ice and cold snaps can still happen anywhere.
When will El Niño end?
NOAA's strength table shows the event weakening during spring 2027, with neutral conditions becoming the most likely outcome by around April to June 2027.
