I went out 2 years ago to Chandler Air Service in Phoenix AZ. Flew about 30 hours in 2 weeks. It was perfect VFR weather every single day. Visibility in excess of 30 miles but even towards the end of September...incredibly hot! (40 degrees C+). Good fun transiting the Phoenix Class B and overflying Sky Harbor whilst having jets landing right under your little Cessna.
