Where the models agree, where they split, and which one has been most accurate here. Free for 14 days, then yearly.
Unlock with ProThe black line is not a simple average. For Treble Cone (southern 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).

El Niño Outlook · Winter 2026
Treble Cone 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 6 past El Niño winters at Treble Cone, ERA5 season snowfall median was 143 cm (56 in), about this resort’s long-term median. This is a historical analog from reanalysis — not a prediction of this winter’s storm track.
