How these numbers are calculated
  • Powder day — at least 15cm of new snow in 24 hours.
  • Bluebird day — sunshine for at least 60% of daylight, following at least 10cm of snow over the previous 3 days.
  • Rain day — at least 1mm of rain (not snow) at this elevation.
  • Skiable day — at least 30cm of settled snow on the ground.
  • Snow depth is modelled from Open-Meteo / ERA5 reanalysis at 3000m, not measured at the resort. Use it to compare seasons and resorts; use the resort's own report for today's conditions.
  • This resort tops out at 3159m, above what the reanalysis terrain model resolves, so the "Top" figures describe high terrain at 3000m rather than the summit itself.
