Best Time to Visit Chamonix: A Month-by-Month Guide

The honest answer to "when should I visit Chamonix?" is that it depends on what you want to do. The valley is busy and beautiful in both summer and winter, and the quieter months in between have their own appeal. Here's a month-by-month guide to help you choose the best time to visit Chamonix for your trip.

Quick Answer

• Hiking and trail running: late June to mid-September, with July and August the most reliable.

• Skiing and snowboarding: January to March for the best snow, with February the busiest.

• Fewer crowds and clear weather: September and early October.

• Best value: the shoulder months, outside school holidays.

December to March: Ski Season

The Chamonix Valley's ski areas generally open in mid-December and run to mid-April, with Grands Montets open later, into early May. The Aiguille du Midi reopens in mid-December after its autumn break. December can be hit and miss for snow, while January to March is the most dependable window. February coincides with school holidays and is the busiest month, so book early. We cover what to reserve and which pass to buy in our guide to planning a winter ski trip to Chamonix.

April: Spring Skiing

Snow lingers at altitude while the valley floor warms up, so April suits anyone who wants spring skiing without the winter crowds. Most ski areas close mid-month, but higher terrain can stay open longer. Expect changeable weather, with sunshine, rain and fresh snow possible in the same week.

May: The Quiet Month

May is the valley's real off-season. The ski lifts have closed, the summer lifts haven't started, and the higher trails are still under snow. Many restaurants and shops take a break. It's peaceful and cheap, but it isn't the month to visit if you want a full programme of activities. Lower valley walks are your best option.

June: Summer Begins

The summer lifts start opening in June, wildflowers appear in the meadows and the valley turns green. Snow can linger on the higher routes well into the month, so check conditions before heading above 2,000m. Afternoon thunderstorms become more common as the month goes on.

July and August: Peak Summer

The warmest and most settled months, with long days and every lift, trail and restaurant running. It's the best time for high-altitude hiking and the busiest, so book accommodation and lift slots ahead. Late August brings UTMB week, which fills the valley completely, as we explain in our guide to what to expect at UTMB week.

September: The Insider's Month

Many repeat visitors call September the best month of the year. The crowds thin, the trails empty and the light is clear, while the weather is often still good. Prices ease too. For more, see why September is one of the best months to visit Chamonix.

October: Autumn Calm

Golden larches, crisp air and very few visitors. The Aiguille du Midi stays open until early November, but most other lifts have closed, and some restaurants shut for the break between seasons. Our guide to what's open in Chamonix in October has the details.

November: Between Seasons

The quietest and wettest month. The Aiguille du Midi closes for maintenance, snow is on its way but not here yet, and a lot of the valley takes a rest. Visit only if you're after complete peace, or a very cheap break with low expectations for activities.
