Does this include snowmaking?

No. These figures are modelled natural snow only, so groomed pistes often ski better than this.

Snow is modelled from thirty winters of ERA5 weather data, natural snow only. It ignores snowmaking, grooming and wind, so use it to compare places, dates and heights, not as a guarantee. Always check local avalanche bulletins before going off-piste.
