SnowSure™ blend — verified model weighting

The black line is not a simple average. For Andermatt-Sedrun (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.

El Niño Outlook · Winter 2026-27

Andermatt-Sedrun El Niño rank & forecast

Andermatt-Sedrun ranks Under review SnowSure resorts — Tier A, +19% 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).

Under reviewTier A — Prime El Niño terrain

Strong-event signal: +19% vs this resort's 30-yr avg

This resort carries no separate rank: its 30-year record is identical to andermatt, which is the ranked entry for this measurement. At ~31km resolution the reanalysis cannot resolve them as different mountains, so publishing both would be publishing one number twice.

'97-98 −10%'15-16 −10%'23-24 +76%

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.
