Method & sources

The composite score weights snow reliability against the historical baseline, pulls in live conditions where available, then adjusts for how much hassle the trip actually is for your group.

01ERA5-Land hourly grid → daily SWE & snow depth at the resort cell.
02Bias-correct against ground stations (SLF / Météo-France nivôse).
03Build per-week climatological percentile · 35 winters.
04Anomaly = current week vs. cell's own 30-year baseline.
05Snow-sure read at the highest-snow cell within ~15km. When most resorts are bare, ranking shifts toward this, surfacing glaciers in shoulder seasons.
06Weight + rank against your origin & vibe profile.
