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

Météo-France snow observation network (poste nivo « LA GIETTAZ » (1217 m, à 5.9 km)) — total snow depth recorded by the resort observers, open archive. During the season the daily report prevails. The percentage is the share of readings with at least 30 cm on the ground; “—”: month without readings.

Total snow depth on the ground measured at 06:00 at the Météo-France “Flaine” station (1620 m, 15 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 1620 m, well below the top of the ski area (2373 m), where snow lies deeper. In season, the resort’s daily report prevails. Snowfall figures are the fresh snow depth over 24 hours recorded at the same station (the HNEIGEF column): a day of snowfall is a day with 1 cm or more, and only winters measured 95 % of the time on that column are counted — which is why the record can be longer or shorter than the one for snow on the ground. More snow always falls than remains: some melts, settles or blows away.

Why altitude matters. Portes du Mont-Blanc stretches from 819 m to 2,373 m: snow lies longest at the top of the ski area, which is why the two depths are reported separately.
