Planning a trip to Phoenix can be tricky. You can get some great rates at fantastic resorts in the summer -- but before you make your reservation, make sure you understand Phoenix weather. We have about five months of summer, and the weather in Phoenix can be brutal if you aren't used to it.

You will see average temperatures for the Phoenix area published in various places, and they will vary by a degree or two. Keep in mind that the official temperature for Phoenix is monitored at Phoenix Sky Harbor International Airport in downtown Phoenix. Suburbs of Phoenix may have slightly cooler temperatures on average, with differences being possibly as much as five degrees from the official Phoenix reading.
