Le Grand Coin

Le Grand Coin, located at an altitude of 1350 m, with peaks reaching 1620 m, in the Northern French Alps, benefits from specific alpine weather conditions. This page brings together the 9-day weather forecast for Le Grand Coin: four days in detail from Météo-France (minimum and maximum temperatures, expected snowfall, 0°C isotherm), then an outlook through day 9, along with the ski area snow depth. The Northern French Alps avalanche bulletin is also available below. Forecasts are calibrated to the resort's actual altitude; the first four days come from Météo-France models (AROME/ARPEGE), the outlook from a longer-range, less precise model.

Cumulative forecast: 0 cm at the resort base (1,350 m) and 11 cm at the summit (1,620 m) over the next 4 days (Météo-France forecast).

Snow line over the coming days in Le Grand Coin

• Monday, 8am to noon: snow line around 1,600 m, rain at the base, snow higher up.

Snow line: the altitude above which precipitation falls as snow. It is computed hour by hour, during precipitation, from Météo-France temperature and humidity at altitude: it is the altitude where the wet-bulb temperature rises above 1.3°C (the same definition as the German weather service's snowfall line). Météo-France days only, not the longer-range outlook.
