El Niño Outlook · Winter 2026-27

Diavolezza El Niño rank & forecast

Diavolezza ranks #47 of 488 SnowSure resorts — Tier A, +12% in strong El Niño winters.

Tier A — Prime El Niño terrain: Historically snowed much more than normal in strong El Niño winters (≥ +8% vs this resort’s own 30-year average).

#47 of 488Tier A — Prime El Niño terrain

Strong-event signal: +12% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Diavolezza averaged +12% versus its own 30-year snowfall baseline. The pattern has historically been a friend here. With a record-strength event forecast for winter 2026-27, Diavolezza sits on the favorable side of the ledger. Analog winters: '97-98 -25%, '15-16 -14%, '23-24 +75%. A pattern, not a promise.

'97-98 −25%'15-16 −14%'23-24 +75%

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.

SnowSure™ Forecast Range

Daily Snowfall Forecast by Model

Black line = verified SnowSure™ blend (not a simple average). Weights update weekly from measured snowfall at SNOTEL stations and resort reports.

SnowSure™ blend — verified model weighting

The black line is not a simple average. For Diavolezza (alps), 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.
