I live at 9000 ft above sea level wher e in the summer termps range in the mid 60's to the upper 90's, but, one has to shop down off the mountain in the basin where temps can hit 105+. There is a good 20-25 degree difference between the two and I usually wear my wool 16 oz kilts without any discomfort. The humidity does spike when the monsoons come but it is still very tolerable and I have never been uncomfortable in the heat even when everyone in shorts is standing around me and complaining
