SnowSure™ blend — verified model weighting

The black line is not a simple average. For Chamrousse Ski (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

Chamrousse Ski El Niño rank & forecast

Chamrousse Ski ranks #185 of 488 SnowSure resorts — Tier C, +2% 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.

#185 of 488Tier C — ENSO-proof

Strong-event signal: +2% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Chamrousse Ski averaged +2% versus its own 30-year snowfall baseline. El Niño has historically made little difference here — this is an ENSO-proof mountain, for winter 2026-27 as in past events. Analog winters: '97-98 -14%, '15-16 -16%, '23-24 +36%. A pattern, not a promise.

'97-98 −14%'15-16 −16%'23-24 +36%

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.
