Freeze line is the height where rain turns to snow. Plain: straight from the models. Marked ○: estimated from temperature. Sun is hours of actual sunshine, not day length; blank means we have no reading.
Every model for High1, side by side for 14 days
Where the models agree, where they split, and which one has been most accurate here.
Unlock with ProThe black line is not a simple average. For High1 (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).

El Niño Outlook · Winter 2026-27
High1 is under review in SnowSure's El Niño dataset — we will not publish a rank against a discontinuous historical series.
This station is under review and carries no rank: its 30-year ERA5 baseline falls below the 80cm floor our methodology commits to, so percentage swings computed on it are unstable by construction. We expect it to benefit from El Niño; our method cannot size that reliably.
In 10 past El Niño winters at High1, ERA5 season snowfall median was 87 cm (34 in), about 31% above this resort’s long-term median. This is a historical analog from reanalysis — not a prediction of this winter’s storm track.
