80% of simulated seasons land between 122" and 227". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.
10,000 simulated 2026-27 seasonsENSO-weighted resampling of 36 real seasons (1990–2026) at Mont-Sainte-Anne, tilted by the live seasonal outlook
Highlighted bars span the middle half of outcomes (P25–P75). The yellow dashed line is a typical season — the median of the last 36 at this mountain.
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.
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.
