SnowSure™ blend — verified model weighting

The black line is not a simple average. For NEKOMA Mountain (japan), 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

NEKOMA Mountain El Niño rank & forecast

NEKOMA Mountain ranks #347 of 488 SnowSure resorts — Tier E, −10% in strong El Niño winters.

Tier EDeep timing play — aim late winter: Strong El Niño winters ran clearly below this resort’s own baseline (≤ −8%). Still skiable — schedule late season; one storm cycle can beat the climatology.

#347 of 488Tier EDeep timing play — aim late winter

Strong-event signal: −10% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), NEKOMA Mountain averaged -9% versus its own 30-year snowfall baseline. Historically this is a timing play rather than a reason to stay home: aim for late winter (February–March) in winter 2026-27. Analog winters: '97-98 -28%, '15-16 -45%, '23-24 +45%. A pattern, not a promise.
