SnowSure™ blend — verified model weighting

The black line is not a simple average. For Aspen Mountain (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

Aspen Mountain El Niño rank & forecast

Aspen Mountain ranks #204 of 488 SnowSure resorts — Tier C, +1% in strong El Niño winters.

Tier C — ENSO-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.

#204 of 488Tier C — ENSO-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), Aspen Mountain averaged +1% versus its own 30-year snowfall baseline — effectively ENSO-proof. Aspen Mountain 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 +0%, '23-24 +3%.

'97-98 −1%'15-16 0%'23-24 +3%

Signal = average snowfall in the three strongest El Niño winters since 1996 ('97-98, '15-16, '23-24) vs this resort's own 30-year ERA5 baseline. n=3 — a lean, not a law. Updated monthly against measured snowfall Dec–Mar.
