SnowSure™ blend — verified model weighting

The black line is not a simple average. For St-Luc-Chandolin (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

St-Luc-Chandolin El Niño rank & forecast

St-Luc-Chandolin ranks #120 of 488 SnowSure resorts — Tier B, +7% in strong El Niño winters.

Tier B — Favored: Modest El Niño upside (+3% to +8% vs normal). Often a solid pick, without the biggest Andes-style swings.

#120 of 488Tier B — Favored

Strong-event signal: +7% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), St-Luc-Chandolin averaged +7% versus its own 30-year snowfall baseline. The pattern has historically leaned mildly in this resort's favor for winter 2026-27. Analog winters: '97-98 -16%, '15-16 +1%, '23-24 +36%. A pattern, not a promise.

'97-98 −16%'15-16 +1%'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.

Key

What the tiers mean

% vs each resort's own 30-year average in strong El Niño winters.

Tier	Signal	Means
A — Prime terrain	≥ +8%	Historically much snowier than normal.
B — Favored	+3% to +8%	Modest upside vs normal.
C — ENSO-proof	about −3% to +3%	Near-normal snowfall — a hedge, not a jackpot or bust.
D — Late bloomer	−3% to −8%	Often lighter early — aim Feb–Mar.
E — Timing play	≤ −8%	Often lighter overall — aim late winter.
