Le Boréon

Le Boréon, located at an altitude of 1500 m, with peaks reaching 1860 m, in the Southern French Alps, benefits from specific alpine weather conditions. This page brings together the 9-day weather forecast for Le Boréon: 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 Southern 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.

9-day snowfall forecast

Cumulative forecast: 0 cm at the resort base (1,500 m) and 0 cm at the summit (1,860 m) over the next 4 days (Météo-France forecast). For the following days, the outlook is given as a range and is not included in this total.

Snow line over the coming days in Le Boréon

No snow forecast on the ski area over the next 4 days: the chart shows the snow line altitude during precipitation.

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.
