La Pierre Saint Martin, located at an altitude of 1650 m, with peaks reaching 2150 m, in the Pyrenees, benefits from specific alpine weather conditions. This page brings together the 9-day weather forecast for La Pierre Saint Martin: 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 Pyrenees avalanche bulletin is also available below.

Snow line over the coming days in La Pierre Saint Martin
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.
