Catedral (Bariloche) AR
The short answer: PassCast projects a median of 180" at Catedral (Bariloche) for 2026 — 98% of a typical season — with a skiability rating of 52/100, ~7 powder days, and Jul–Aug as the prime window. Updated daily from 10,000 simulations.
80% of simulated seasons land between 132" and 264". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.

What's driving this forecast
The 2026 season is simulated by resampling Catedral (Bariloche)'s historical seasons weighted toward El Niño analog years. NOAA CPC El Niño Advisory (June 11, 2026): El Niño conditions are present and expected to strengthen into winter 2026-27, with a 63% chance of a very strong event (Niño3.4 ≥ +2.0°C) during Nov-Jan. CPC DJF strength odds: very strong 46%, strong 33%, moderate 16%. IRI (June 22) concurs at 98% El Niño for DJF. Latest observed ONI (AMJ 2026): +1.0.
The strongest ENSO-snow teleconnection of any ski region on Earth: El Niño parks the subtropical jet over 30-37°S and hammers the high Andes (Masiokas et al. 2006). Portillo averages ~+45% snowfall in warm-ENSO seasons; storms are characteristically back-loaded into July-September. Applied as a +16% tilt at partial weight.
The 51-member SEAS5 seasonal forecast puts Aug–Sep snowfall at this grid point at 66% of its ERA5 normal (ensemble mean 50", spread 30–73"). Applied as a -8% tilt — experimental, heavily shrunk and clamped because seasonal models and reanalysis have different biases.
The reanalysis archive could not be reached, so snow already on the ground is not blended in today — this outlook is running on climate drivers alone and will pick the observations back up on the next refresh.
The regional readAndes · from the 2026-27 outlook
This is El Niño's flagship ski trade: with Niño3.4 possibly reaching +2.0°C, the subtropical jet should park over central Chile and hammer the 30-37°S Andes through late winter — Portillo averages roughly +45% snowfall in warm-ENSO seasons (Masiokas et al. 2006; bestsnow.net). The dry, slow June 2026 start fits the pattern rather than breaking it: 1997 and 2015 also began quietly before multi-meter July-September storm cycles produced some of the deepest Portillo bases on record. August and September should be the payoff months. If you hold a multi-resort pass, this is the hemisphere to spend it in.
