Snow & Weather Conditions at Sun Valley
Central Idaho receives a mix of Pacific moisture and cold continental air, producing reliable snowfall with good powder quality. The high elevation ensures a cold, consistent climate that favours natural snow preservation. Storms frequently deliver generous snowfall totals, and the altitude keeps the snowpack dense and skiable throughout the core winter months. Typical annual snowfall ranges from 6–10 metres, with a mid-season base depth often surpassing 2 metres.
Best Time to Ski at Sun Valley
Season runs late November to mid-April. January and February offer the most reliable conditions. For the highest probability of fresh powder at Sun Valley, plan your visit during January and February when storm cycles are most frequent and temperatures keep the snowpack cold and dry. March can also deliver excellent conditions — the snowpack is often at its deepest, and you may find fewer crowds on the mountain.
