How the Ski Decision score works

An explainable planning score, not a stored source metric.

The daily score combines Snow 25%, Fresh Snow 15%, Weather 20%, Visibility 15%, Wind 15%, Operation 10%. Missing inputs reduce confidence rather than automatically lowering the skiing score. Rain at ski altitude, strong wind and poor visibility are explicit penalties; fresh snow and a well-supported existing base are positive signals.

The overall score should be used together with official lift status, avalanche bulletins, closures and local safety guidance. It does not replace operational or avalanche information.
