Calibrated reanalysis, 1950–2025. Bars are each winter's mean base, rules each decade's mean. 2020–2025 holds 6 winters, not ten. Every figure here averages a full season, so none of them will match the readings for your chosen weeks above.

Method & sources

We weigh snow reliability against this resort's own history, add live conditions where we have them, then adjust for how hard the trip is for your group.
