LOCAL CONTEXT
About Sun Valley weather
Sun Valley’s high, sheltered Wood River Valley earns its name — surrounding ranges block much of the Pacific gloom, leaving cold, sunny winters between storms. Clear nights pool frigid air on the valley floor, so mornings run far colder than the sunlit slopes above.
