SnowSure™ blend — verified model weighting

The black line is not a simple average. For Snowmass (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

Snowmass El Niño rank & forecast

Snowmass ranks #226 of 488 SnowSure resorts — Tier C, −1% in strong El Niño winters.

Tier CENSO-proof: Strong El Niño winters looked like a normal year here — within about ±3% of this resort’s own 30-year snowfall average. Not a jackpot, not a bust: a hedge if you’re planning around El Niño.

#226 of 488Tier CENSO-proof

Strong-event signal: −1% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Snowmass averaged -1% versus its own 30-year snowfall baseline — effectively ENSO-proof. Snowmass has held within a few percent of normal across every phase of the Pacific cycle, making it one of the safest bets of a record El Niño winter 2026-27. Analog winters: '97-98 +1%, '15-16 -1%, '23-24 -2%.
