30 cm on the ground: the benchmark for groomed-piste skiing. Bar = monthly average depth; percentage = share of time above 30 cm.

  • Good skiing: 30 cm on more than 8 days in 10
  • Variable: 30 cm on 5 to 8 days in 10
  • Insufficient: 30 cm less than one day in two
Estimate from the ERA5-Land reanalysis (Open-Meteo), about 9 km grid at 1,048 m. Not a resort measurement: during the season the daily report prevails. The percentage is the share of time with at least 30 cm on the ground.

Snowfall: no long enough record of fresh snow at this station. Rather than an estimate, we show nothing.

Total snow depth on the ground measured at 06:00 at the Météo-France “LE TOUR” station (1500 m, 10.9 km away), from the open “Daily climatological data” dataset (Open Licence 2.0). The season is counted from 1 December to 15 April; only winters with at least 95 % of those 136 days measured are kept, so no figure here rests on a handful of readings. The reading is taken at 1500 m, well below the top of the ski area (2317 m), where snow lies deeper. In season, the resort’s daily report prevails.
Why altitude matters. Chamonix-Mont-Blanc stretches from 1,035 m to 2,317 m: snow lies longest at the top of the ski area, which is why the two depths are reported separately.
