Val d'Isère in February

December through March gives you the most reliable snow, but each month has its personality. December offers early season excitement and Christmas markets, but limited terrain and unpredictable weather. January delivers the coldest temperatures but often the best powder - plus it's slightly less crowded after New Year. February is peak season for a reason: consistent snow, all lifts running, and that perfect Alpine winter atmosphere. March brings longer days and spring skiing conditions - corn snow in the afternoon, perfect weather for long lunches on mountain terraces. Avoid the first two weeks of February if you hate crowds; French school holidays pack the place. Easter week gets busy again but offers great weather for those who prefer milder temperatures. The resort typically closes in early May, though the glacier connection to Tignes keeps some terrain open through summer for die-hard skiers and snowboarders.
