Today's Weather Situation

Summers bring warm daytime highs around 90°F in Boise and 83°F in Sun Valley. Most of the state falls somewhere in between, with cooler temperatures in the mountains and up north, and warmer weather along the southern plains. Thunderstorms are common across Idaho during the summer months, which are relatively brief (late June to late August). Visitors can expect sunshine 80 percent of the time during the summer and about 50 percent of the time in winter
There really is no bad time for a trip to Idaho; it just depends on your agenda. For skiers, the latter part of the winter brings the deepest snowpack to the mountain resorts. February and March are typically incredible months for skiing at Sun Valley and Silver Mountain. Summers are equally magical as the mountains burst into wildflowers and greenery. Temperatures are just about perfect and most resort towns like Sun Valley and Coeur d’Alene have lots of festivals and special events planned.
