Snow Report, 24 December 2025

By Nye Erskine, Updated

Christmas week has arrived in the Chamonix valley and the mountains are looking in good shape as the festive period gets underway. There is a proper winter feel around town now, with cold mornings, snow settled on the upper slopes and steady traffic heading up the lifts. After a gradual build through early December, conditions are starting to feel more reliable, especially higher up, and the atmosphere across the valley reflects that mix of excitement and anticipation that always comes with a Christmas in the mountains.

Snow and Weather Summary

Current snow depths across the Chamonix valley are strongest at altitude, with around 140 to 180 cm reported on the highest sectors such as Grands Montets and the Brévent Flégère area, while snow depth in the valley sits closer to 30 to 50 cm depending on location. Recent snowfall earlier in the week delivered a light refresh to upper slopes, helping improve surface conditions and visibility. Temperatures have remained cold overnight, with freezing levels generally below 1500 m, which has helped preserve snow quality on prepared pistes. Over the next few days the forecast suggests largely stable weather with cold nights and daytime temperatures hovering just below or around freezing at mid mountain level. Winds are expected to remain light to moderate, meaning lift operations should be relatively smooth. Lower runs still feel thinner and more variable, but snowmaking combined with colder temperatures is steadily improving coverage.

Outlook & What’s On

The festive period in Chamonix brings a busy events calendar, with Christmas Eve celebrations, village activities and family friendly entertainment taking place across the valley. The Christmas markets and the parades scheduled are adding to the Christmas atmosphere. From a skiing point of view, the outlook remains steady rather than dramatic, with no major snowfall forecast immediately but cold conditions set to continue. This should help maintain the current snowpack and allow piste teams to keep runs in good condition throughout the week. For the best skiing, higher altitude areas will continue to offer the most consistent snow, while access to lower terrain should gradually improve as the cold spell continues.

Snow Takeaway

Chamonix is set up well for Christmas week skiing, particularly at altitude where snow cover is solid and skiing conditions are reliable. Lower slopes still require some care, but overall the trend is positive and the snowpack is holding well. If you are visiting over the festive period, focus on higher terrain and prepared pistes for the best experience.
