Mont-Sainte-Anne QC
The short answer: PassCast projects a median of 155" at Mont-Sainte-Anne for 2026-27 — 87% of a typical season — with a skiability rating of 43/100, ~7 powder days, and Jan–Feb as the prime window. Updated daily from 10,000 simulations.
80% of simulated seasons land between 117" and 221". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.

What's driving this forecast
The 2026-27 season is simulated by resampling Mont-Sainte-Anne'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.
Quebec's El Niño signal is thermal — strong events run 2-4°C mild, converting marginal storms to rain (1997-98 was 'the winter El Niño cancelled' per Environment Canada). The juiced subtropical jet can still land big synoptic storms when cold air holds. Applied as a -5% tilt at partial weight.
The 51-member SEAS5 seasonal forecast puts Nov–Jan snowfall at this grid point at 87% of its ERA5 normal (ensemble mean 86", spread 61–112"). Applied as a -3% tilt — experimental, heavily shrunk and clamped because seasonal models and reanalysis have different biases.
Day-to-day weather models have no skill this far out, so the near-term forecast contributes 0% weight today. The simulation leans entirely on ENSO-conditioned climatology — exactly what an honest seasonal outlook should do in summer. Weighting shifts toward live forecasts as opening day approaches.
The regional readEastern Canada · from the 2026-27 outlook
Quebec's strong-El Niño problem is warmth more than storm count: 1997-98 — the winter Environment Canada says El Niño 'cancelled' — brought Quebec City its mildest winter on record, and 2015-16 repeated the trick at Tremblant. The wildcard is the El Niño-fueled subtropical jet, which can still land heavyweight synoptic snowstorms on the St. Lawrence when cold air cooperates. Expect a below-average, snowmaking-dependent season with a compressed mid-January-to-early-March core.

Mont-Sainte-Anne 2026-27: straight answers
- How much snow will Mont-Sainte-Anne get in the 2026-27 season?
- PassCast's latest 10,000-run simulation (reseeded 2026-07-10) puts the median at 155 inches — 87% of a typical season at Mont-Sainte-Anne — with 80% of outcomes between 117 and 221 inches. The forecast blends Mont-Sainte-Anne's own 36-season ENSO analog record with NOAA's seasonal outlook and the ECMWF SEAS5 ensemble.
- Is a season pass worth it for Mont-Sainte-Anne in 2026-27?
- Mont-Sainte-Anne is on Epic Pass for 2026-27, but with day caps at this mountain the pass only pays off combined with days at its other resorts — the simulator on this page runs that math for your plan.
- When is the best time to ski Mont-Sainte-Anne in 2026-27?
- Jan–Feb is the prime window — the deepest contiguous stretch of the ENSO-conditioned season at Mont-Sainte-Anne. Month-by-month medians are charted on this page.
- How reliable will the snow be at Mont-Sainte-Anne this season?
- The simulation gives Mont-Sainte-Anne a 30% chance of beating its typical season and a median of about 7 six-inch-plus powder days. Its skiability rating is 43/100 (“Selective — time it well”), updated daily.
