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 Mt. Seymour, 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 Mt. Seymour (rockies), 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
Mt. Seymour 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 record has an era discontinuity our quality pass cannot correct for, so a percentage against it would not mean what it appears to mean.
In 10 past El Niño winters at Mt. Seymour, ERA5 season snowfall median was 97 cm (38 in), about 57% below this resort’s long-term median. This is a historical analog from reanalysis — not a prediction of this winter’s storm track.
