July is generally the hottest month of the year in Colorado. The peak summer weather is scorching hot in the plains and the desert lands. The average high temperatures in the state are between 78°F (25.6°C) to 94°F (34.4°C). Many places touch 95°F (35°C) and a thermometer reading of 100°F (37.8°C) is common - in fact, Colorado records many days continuously over 95°F (35°C). Summer nights have comfortable temperatures of 45°F (7.2°C) to 60°F (15.6°C). Tourists arrive in droves for camping, fishing, biking, and trailing in the national parks - the Rocky Mountain National Park buzzes with visitors, and the camping grounds and lodges are scarcely vacant. Rain is scarce in Colorado, and July registers no more than 1" (25mm) to 2" (51mm). The average humidity seldom exceeds 50% during the summer, as long days with 15 hours of daylight are the norm. Brilliant sunshine and clear blue skies are the features of Colorado summers - wear light clothing with full sleeves and hats to combat the blazing sun.
