Temperature °C< −10 / −10 / 0 / 10 / 20 / 30+

Wind km/h< 10 / 10 / 29 / 50 / 75+

Each colour starts at the value shown. Wind colours match across all three units. Dry cells stay neutral. Colours describe the displayed values, not official weather warnings.

Preparing forecast graphs…

Times and values match the detailed forecast. Tap or point at a value for details. Scroll each chart sideways for later days. Rain / precipitation is the total water equivalent per forecast interval, including snow; snowfall is fresh snow per interval, not snow depth.

GFS and ECMWF model comparison. Each model retains its own forecast times and horizon. Precipitation and snowfall amounts cover their own forecast intervals; these can differ between models.

Forecast values and model notes

Les Portes du Mont-Blanc - Low lift station

ECMWF IFS · Run 2026-10-17 00:00:00 UTC · 10 days · Times: UTC.
Coordinates: 45.9159231°N, 6.6002106°E · Requested elevation: 1031 m. Model terrain: 1431 m. Terrain and 1000/925/850/700 hPa profiles are used for height estimates.
Outside the available profile, temperature uses an estimated 5.5°C/km height correction; wind retains the nearest available model-level value. Humidity is estimated with adjusted pressure and temperature.
These are altitude estimates, not a simulation of local mountain terrain. Precipitation, cloud and sea-level pressure use horizontal interpolation only.
Precipitation includes rain and snow water equivalent: preceding 3 hours through day 6, then 6 hours (see cell tooltip). Snow (cm) estimates fresh snowfall from precipitation and temperature using the GFS conversion; it is not snow depth on the ground. Freezing (m) uses additional 600/500 hPa temperatures when available and estimates the lowest resolved 0°C crossing above sea level. When all sampled levels are warm, the upper profile limit is shown (see tooltip). < marks an entirely cold sampled profile and its lower height limit. No extrapolation is used.
