SnowSure™ blend — verified model weighting

The black line is not a simple average. For Nozawa Onsen (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

Nozawa Onsen El Niño rank & forecast

Nozawa Onsen ranks #429 of 488 SnowSure resorts — Tier E, −17% in strong El Niño winters.

Tier E — Deep 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.

#429 of 488Tier E — Deep timing play — aim late winter

Strong-event signal: −17% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Nozawa Onsen averaged -17% versus its own 30-year snowfall baseline. The honest read: this is the fleet's deepest timing play. The snow still comes — but in Japan the El Niño hit lands on the season's edges, not the heart of the sea-effect window. Point your winter 2026-27 trip at the mid-winter core (January to mid-February), stay flexible on dates, and watch our monthly scorecard. Analog winters: '97-98 -30%, '15-16 -42%, '23-24 +20%. One caveat that always holds: a single storm cycle can beat the climatology.
