Super El Niño is Coming: What it Means for Our Winter.

If you skied here last winter, you remember how thin it was. Colorado had a historically low snow season, with snowpack well below normal from December through April because of erratic storms and very warm temperatures (OpenSnow). Now the Pacific is setting up a possible plot twist: one of the strongest El Niños ever recorded. Everyone from federal forecasters to resort press offices is dusting off the word "powder."

Here's what's known, what's likely, and what's still a coin flip for the Vail Valley.

NOAA's Climate Prediction Center says El Niño is strengthening, with better than 90% odds of a very strong event this fall and winter, and a 75% chance of a record-setter that would exceed every El Niño back to 1950 (NOAA, Sept. 10). The latest weekly reading for the key Niño-3.4 zone has hit +2.0°C, the informal "super" line, with parts of the eastern Pacific running more than 3°C above normal (NOAA, Sept. 17).

Scale per OpenSnow; current reading per NOAA.

Scientists at UCAR (University Corporation for Atmospheric Research), the consortium that runs NCAR (National Center for Atmospheric Research), note that "super" is the media's word for very strong. They also note that as the oceans warm overall, forecasters are adjusting how they measure El Niño by subtracting the background warming (UCAR). NOAA's newer index, the Relative Oceanic Niño Index, works this way.

El Niño pushes the winter jet stream south. That usually means more storms across the southern U.S. and a warmer, drier north, and Colorado sits right on the seam between the two (NOAA).

OpenSnow sees the clearest snow signal in the San Juans and along the eastern side of the Divide, including Wolf Creek, Telluride, Winter Park and Loveland. Vail, Aspen, Breckenridge, Copper and Steamboat show no clear signal in either direction (OpenSnow). The National Weather Service in Grand Junction agrees: its hydrologist puts western Colorado at roughly 50-50 for a wetter or drier winter (Colorado Sun via HPPR).

Colorado's assistant state climatologist, Peter Goble, adds a useful reality check. El Niño years have tended to be wetter across much of the state, but that hasn't lined up neatly with peak snowpack, and he hasn't yet seen a clear El Niño fingerprint on Colorado's weather. He worries people are getting overexcited.

NOAA adds a wrinkle. The three biggest past El Niños (1982-83, 1997-98, 2015-16) all happened while a long-term North Pacific pattern called the PDO was in its warm phase. This year it's in its cool phase, which could dampen typical El Niño effects in some areas. NOAA also says that with an event this strong, El Niño-type impacts are more likely but not guaranteed (NOAA).

OpenSnow's Sam Collentine looked at the ten El Niño winters since 1982 using the snowpack station on Vail Mountain. On March 31, the median El Niño winter came in at 104% of normal, essentially average, with a wide range from 78% to 131% (OpenSnow). The last super event, 2015-16, landed right at normal.

The more useful finding is timing. At Vail, El Niño winters have tended to run well ahead of normal in October and November, fall short in December and January, then finish strong in March and April. OpenSnow's broader Colorado outlook shows the same shape: a solid start, a softer middle, a stronger finish.

The closest analog to this year is 1997-98, since this year's ocean reading is the warmest since then, per OpenSnow. Statewide that winter finished at 101% of normal, but Vail's own station ended at 86%. Analogs are guides, not promises.

Warmth is a bigger worry than dryness. OpenSnow favors above-average temperatures for northern Colorado (OpenSnow), and NOAA's outlooks lean warm across many areas west of the Rockies from late fall through early spring (NOAA). But OpenSnow stresses that last winter was the warmest on record for much of the West and is unlikely to repeat, even if the warm outlook verifies.

Elevation is our friend. OpenSnow's Alan Smith told the Denver Gazette that Colorado is more resilient to rain-instead-of-snow than nearly anywhere else, while cautioning that snow density and quality could change (Denver Gazette). That points to the valley floor and lower terrain being more exposed than the upper mountain.

The stakes go beyond lift tickets. Colorado is coming off a record-low snowpack (Denver Gazette) and a punishing summer drought, and climatologists say they can't yet promise relief (Colorado Sun via HPPR). A healthy snowpack matters for agriculture, recreation and water supplies well beyond the ski season.

Vail Mountain is targeting a Nov. 13 opening and Beaver Creek Nov. 25, according to Vail Resorts' August announcement.

These are targets, and they depend on weather. Vail Resorts' Bill Rock said the company is taking an aggressive approach to snowmaking whether or not the super El Niño delivers, and the company says it has invested more than $100 million in snowmaking across its resorts since 2015.

Flexibility will beat forecasting this winter.

Two NOAA releases will show whether the outlook is shifting as El Niño keeps strengthening. On Oct 8, 2026, NOAA issues its next monthly El Niño update (NOAA). On Oct 15, 2026, it releases its next set of seasonal outlooks, with another month of data behind them (NOAA).

After a punishing year, the most likely outcome is a real step up: solid odds of a strong start and a strong finish, bracketing a midwinter that's simply a coin flip instead of a bad bet. That's not a guaranteed epic season, but the setup is genuinely better than it's been in years, and there's real upside if the storms cooperate.
