It’s the mountains so almost anything is possible on each day.
Normally it should be sunny and around mid to high 20s in the day but it will cool down at night so please bring suitable clothes.
If you’re going up the mountain in the Gondola or to the top of the Croix de Fer then you’ll want to bring a warm layer as both are over 2000m so cooler than Vaujany which is at 1250m.
In Allemond/Lake Verney it’ll probably be 5 degrees warmer.
Rain is always possible so please be prepared.
On this date in the last 2 years it’s been 28 degrees one year and cold enough for snow above 2000m the next.
If you plan to go walking or up the mountain, good trail trainers or walking boots are recommended.
For the wedding we’d recommend flat shoes for the Ceilidh and walking between the venues.
