Weather at Zermatt/Breuil-Cervinia/Valtournenche - Matterhorn

The ski area runs from 1,562 to 3,899 m above sea level - a 2,337 m vertical. In January the daytime average is 0 °C at the base and -16 °C at the summit. Plan for that 15 °C gap: what feels right at the base will be cold up top. The summit sits around -16 °C at the same time of year - at that point the wind matters more than the thermometer.

Average daytime highs at the summit stay below freezing from September through May. Last season brought 710 cm of snow here. The snowiest month was May: 172 cm over 8 days with snowfall. The snowpack was deepest in February, at roughly 98 cm. These are observations from a single season, not a long-term norm: a snowy year here can be twice a lean one.

Snowmaking covers 80% of the runs, so the start of the season barely depends on when natural snow arrives.

By May the base is around 9 °C while the summit still holds -6 °C: on days like that, start early and stay high. Based on monthly averages and the resort elevations. For the coming days, see the forecast above.
