Average June Low Temperatures
The urban heat island (UHI) is a phenomenon of higher nighttime temperatures in the urban core compared to the surrounding rural countryside. Urban surfaces cool more slowly because impervious surfaces trap heat during the day and then radiate that heat back into the atmosphere at night. Typical nighttime temperatures in urbanized Phoenix are 10°F warmer than surrounding rural areas. In addition, urban attributes such as transportation and industry elevate urban temperatures.
The increase in minimum daily temperatures reduces human comfort levels, increases energy use, and jeopardizes tourism and investment opportunities for the region if people choose to locate elsewhere.

Average June Low Temperature Recorded at Sky Harbor Airport
Visualization Notes:
This graph shows the average low temperature for the month of June in the years 1948 through 2013. The average low temperature for June has risen by about ten degrees during the last sixty years. This is an indication of the urban heat island phenomenon of higher nighttime temperatures in the urban core compared to the surrounding rural countryside. Temperatures were recorded at the Phoenix Sky Harbor International Airport climate monitoring station.
