What's driving this forecast
The 2026-27 season is simulated by resampling Tremblant'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.
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.
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.

- Breakeven is 7.7 days at ~$132/day window tickets; you plan 10.
- Covers Tremblant (unlimited).
- Snow-adjusted across the simulated seasons, expect ~9.4 covered days; the pass beats window tickets in 100% of 10,000 simulated seasons (mean saving $225).
- Breakeven is 11.0 days at ~$132/day window tickets; you plan 10.
- Covers Tremblant (unlimited).
- Snow-adjusted across the simulated seasons, expect ~9.4 covered days; the pass beats window tickets in 5% of 10,000 simulated seasons (mean shortfall $205).
- At this plan, window tickets or a cheaper product wins.
