SnowSure™ blend — verified model weighting

The black line is not a simple average. For Mont-Sainte-Anne (rockies), we combine seven global weather models using weights learned from daily forecast verification — comparing each model's prediction to measured snowfall (SNOTEL, resort reports, ERA5).

  • 1.Horizon buckets: days 1–3, 4–7, and 8–14 each get separate weights — short-range skill differs from long-range.
  • 2.Regional calibration: weights come from verified error in this geography (Rockies, Alps, Japan, etc.), recalculated weekly.
  • 3.Ground truth only: we never grade a forecast against another model — only against measured snow.

El Niño Outlook · Winter 2026-27

Mont-Sainte-Anne El Niño rank & forecast

Mont-Sainte-Anne ranks #274 of 488 SnowSure resorts — Tier D, −5% in strong El Niño winters.

Tier D — Late bloomer — aim Feb–Mar: Often a bit lighter early (−3% to −8% vs normal). History favors waiting for peak-depth months (often Feb–Mar) rather than skipping the resort.

#274 of 488Tier D — Late bloomer — aim Feb–Mar

Strong-event signal: −5% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Mont-Sainte-Anne averaged -5% versus its own 30-year snowfall baseline. Historically this is a timing play rather than a reason to stay home: aim for late winter (February–March) in winter 2026-27. Analog winters: '97-98 -3%, '15-16 -3%, '23-24 -9%. A pattern, not a promise.
