Expect highs in Chamonix around 66 °F and lows around 55 °F in June, though in 2019, temps in June hit 90 °F. There is generally a 30% chance of rain, so bring your rain jacket. Chamonix is located at 3,400 feet. Check the weather as you pack!
As we go up into the mountains, we will be staying in a mountain hut at almost 9,000 ft. Expect highs in the 40s and lows in the 30s. As we further ascend up to almost 12,000 ft, the temperature will continue to drop. Though we won’t spend long up there at that elevation and temperature, we do want you to have this information so you can pack appropriately. Please let us know in advance if you need to rent warm clothing, like a warm coat or waterproof jacket and pants, in Chamonix.
