Snow Report, 11 December 2025

By Nye Erskine, Updated

Winter is gradually settling over the Chamonix valley and the high mountains are beginning to look properly wintry. Snow has continued to build at altitude and the forecast over the coming days is hinting at a little more to come. It is still early season here, but for anyone considering a December visit, the upper slopes are starting to offer some encouraging signs.

Snow & Weather Summary

Recent data shows that the upper mountain snow depth is sitting at around 140 centimetres. Coverage at valley level remains very limited, which is normal for this stage of the season in Chamonix. A small top up of fresh snow is expected this week, mostly falling on the higher slopes, and temperatures are set to remain cold at altitude. This should help preserve the existing snow and slowly build the base across the upper ski areas.

On the ground this means that the best skiing options are found higher up above the valley floor. Prepared pistes on the upper mountains should ski reasonably well, especially in the mornings when overnight freezing firms up the surface. Lower slopes will continue to rely heavily on artificial snow and may not offer consistent coverage yet, so it is best to plan to stay high for now.

Outlook & What’s On

Chamonix often takes a little longer than some other resorts to build valley level cover, and this year appears to be following that familiar pattern. The good news is that the upper areas are progressing steadily, with cold weather helping the snow to settle. If the small snowfall forecast arrives, it should provide a useful refresh ahead of the weekend.

Events are beginning to appear on the calendar as the festive season approaches. Early December usually brings guided mountain outings, Christmas markets around the villages, and a handful of evening events in the town centre. As more lifts open over the coming days the atmosphere is expected to grow livelier, so it is worth keeping an eye on local listings if you are visiting soon.

Snow Takeaway

Chamonix is not offering full winter coverage yet, but the upper areas are moving in the right direction. With a decent base already in place at altitude and another light snowfall expected this week, there is potential for enjoyable early season turns if you focus on the higher lifts and prepared pistes. For travellers planning a mid-December visit, conditions look set to continue improving.
