We were in Montana a few years ago in July and the day temps averaged out to 92 degrees, but, with the dry high mountain air as soon as the sun went down it got very pleasant. In fact Carla got pretty chilly when she took her walks at dawn. It was hot during the day, but, the dryness made it bearable for us. We who are used to humidities of 60-80% in the northeast for the summers.
