Late May through September is the production window statewide. Sun Valley and ski-corridor cooler. Wildfire-smoke residue handling June through October in active fire years. Treasure Valley early-morning working windows recommended through July-August (extreme heat).
September through October is the cleanest production stretch statewide outside of wildfire-smoke events. Pre-winter residential rush September-October. First hard frost in higher-elevation corridors mid-September.
Treasure Valley exterior reduced December through February. Northern Idaho panhandle and high-elevation corridor exterior fully shut down December through February.
