Colorado had a cold winter, with record amounts of snow fall in the mountains, followed by a cold dry spring. Summer is now starting to act rather normal. Denver and the eastern plains normally get 30 days of 90+ temperatures each summer, but due to the altitude of 5,000 feet plus on the plains (Colorado's average altitude is 6350 ft). the nights normally fall into the 50's or low 60's. Makes for good sleeping weather. The altitude at my place is 5,440 feet. - Millet
