Forecast snowfall: 0 mm at 1,000 m, 0 mm at 1,600 m and 0 mm at 2,100 m water equivalent over 24 h from 9 Nov, 20:00 · Open-Meteo · MeteoSwiss ICON-CH1/CH2, issued 9 Nov, 16:00 (Europe/Paris). Forecast source

Le Grand-Bornand is a village in the Aravis range in Haute-Savoie. The operator lists 90 km of pistes and 24 lifts, and Wikipedia names the hamlet of Chinaillon as the main ski centre.

Area covered: This page covers the Le Grand-Bornand alpine ski area as the operator’s interactive map lists it: the sectors Chinaillon, Joyère, Maroly and Rosay/Lachat. Nordic trails and snowshoe routes are not counted. The forecast uses one point at the Rosay gondola valley station, so conditions in Chinaillon and on the upper slopes can differ.

Sources & method

Local reports describe observed conditions. The weather forecast is shown separately; it does not establish piste quality or snow cover.

The illustration connects the three views. It is a schematic, not a route map or a picture of current snow cover.

For Le Grand-Bornand, the 1,000, 1,600 and 2,100 m values are elevation-adjusted model forecasts at the forecast point Rosay gondola valley station, not observations or separate weather stations.

How we calculate this

Wet-bulb: Stull (2011), a near sea-level approximation. Alpine pressure effects and very cold, dry conditions limit accuracy. Potential hours use a −2°C threshold; equipment, water and operating decisions remain unknown. Snow balance uses wet-bulb precipitation partition and a configurable degree-day melt factor. Uncalibrated research model.

How this comparison works+

Daily comparison selects the nearest stored issue to 24 hours earlier (within 6 hours); weekly uses 7 days (within 12 hours). At least six consecutive future hours must match. Source and model version must agree. The comparison describes changes in that forecast period.

This view uses a single forecast. Probabilities and historical accuracy scores are not available.

Snow and lift questions

How much snow is forecast for Le Grand-Bornand ?

For Le Grand-Bornand, the Open-Meteo · MeteoSwiss ICON-CH1/CH2 forecast issued 9 Nov, 16:00 shows modelled snowfall of 0 mm at 1,000 m, 0 mm at 1,600 m and 0 mm at 2,100 m in the 24 hours from 9 Nov, 20:00. Amounts are millimetres of water in the snow, not snow depth. Times are local (Europe/Paris). Forecast source ↗

How deep is the snow in Le Grand-Bornand ?

PisteWindow has no current snow-depth report for Le Grand-Bornand. Forecast figures are modelled snowfall, not snow depth. Official resort information ↗

Which lifts are open in Le Grand-Bornand ?

Lifts: 0 of 25 open (Le Grand-Bornand alpine sectors · source-listed map lifts and downhill pistes; Lumiplay / Le Grand-Bornand; meaning not stated; Retrieved 9 Nov, 19:11 · source time unconfirmed).

How does snowfall differ from snow depth?

Snowfall is the new snow that falls in a period. Snow depth is the total on the ground and also reflects earlier snow, melt and settling. PisteWindow’s forecast shows modelled snowfall as water in millimetres, not depth.

Before your ski day

When does the ski area of Le Grand-Bornand open?

The operator’s downhill skiing page, checked on 8 November 2026, announces a pre-season opening on 5 and 6 December 2026 and continuous operation from 12 December 2026 to 11 April 2027. Dates depend on snow conditions. The lift and piste status shows what is open on a given day.[1][4]

Does the count include Nordic trails and other winter activities?

No. The counts cover the lifts and downhill pistes of the four alpine sectors only. Cross-country trails, snowshoe routes, ski touring routes, sledging runs and the snowpark are listed separately by the operator and are not counted as pistes.[4]

Where do the lift status and snow depth on this page come from?

Lift and piste status comes from the operator’s interactive map and counts only the four alpine sectors Chinaillon, Joyère, Maroly and Rosay/Lachat. The map gives no update time, so the counts are labelled as source-listed. Snow depth comes from the Météo-France station GRAND-BORNAND at 1,447 m, part of a seasonal archive: the page shows its latest reading with the date, or marks snow as unavailable.[4][5]

Are the 1,000, 1,600 and 2,100 m forecasts for Le Grand-Bornand observations?

No. They are model values adjusted to 1,000, 1,600 and 2,100 m, calculated at one representative point (Rosay gondola valley station).[2]
