I like to highlight my winter shots during August and September to remind me that the whole world is not condemned to 110 degrees and above. Yet. August, 2011 was the hottest month in the recorded history of Arizona. The average temperature, including morning lows and afternoon highs, was 98.3 degrees. August also had the highest average high temperature, 109. The highest average low temperature, 87.5. How did I survive? I really don't know, I never went outside almost the entire month.
