Chamonix sits at 1,035 metres (3,396 feet) in the French Alps, at the foot of Mont Blanc, Western Europe’s highest peak at 4,807 metres. The town hosted the first Winter Olympics in 1924 and has been a global centre for skiing, mountaineering, and alpine adventure ever since. Chamonix has an alpine climate with cold, snowy winters ideal for skiing from December through April, and mild summers with daytime highs of 22-23°C (72-73°F) perfect for hiking and climbing from June through September. The valley receives about 1,275mm of precipitation annually, with snowfall averaging 8-10 metres at altitude. About 2.5 million visitors come to Chamonix each year, split roughly evenly between winter sports enthusiasts and summer mountain travellers.
Welcome to Chamonix: An Alpine Year-Round Destination
Chamonix stretches for 15km along the Arve River valley, from the hamlet of Le Tour near the Swiss border to the village of Les Houches near the Mont Blanc Tunnel entrance to Italy. The town centre is compact and pedestrian-friendly, with Rue du Docteur Paccard forming the main axis of shops, restaurants, and bars. Five separate ski areas ring the valley: Grands Montets (expert terrain), Brévent-Flégère (best views), Le Tour-Vallorcine (beginners), Les Houches (tree-lined), and the Vallée Blanche (world-famous off-piste descent). In summer, the same lift system opens access to hundreds of kilometres of hiking trails, including sections of the Tour du Mont Blanc circuit. The Aiguille du Midi cable car, which rises to 3,842 metres in 20 minutes, operates year-round and is Chamonix’s most-visited attraction.
Chamonix has two distinct high seasons. Winter runs from Christmas week through late April, peaking during French school holidays in February. Summer runs from late June through early September, peaking in August. The shoulder seasons (late April to mid-June and October to late November) are much quieter, with many lifts and some businesses closed. September and March offer the best balance of good conditions and manageable crowds. The complete Chamonix weather by month guide breaks down temperatures, snowfall, and sunshine for every month.

Where Is Chamonix and What Shapes Its Weather?
Chamonix is in southeastern France, in the Auvergne-Rhône-Alpes region, bordering both Switzerland and Italy. The town sits in a deep glacial valley oriented northeast-southwest, flanked by the Aiguilles Rouges range to the north and the Mont Blanc massif to the south. This geography creates a distinct microclimate: the Mont Blanc massif acts as a massive weather barrier, forcing moisture-laden air from the Mediterranean and Atlantic upward, producing significant precipitation on the French side. The valley’s orientation means the town centre and Brévent slopes get more afternoon sun, while the Argentière side stays shadier and colder. The Aiguille du Midi summit (3,842m) is typically 15-20°C colder than the valley floor. The closest major city is Geneva, Switzerland (88km), and the nearest Italian town is Courmayeur (22km through the Mont Blanc Tunnel).
