Hell yes it is. When I was stationed in Yuma, AZ (the armpit of the South West) it would get into the high teens to very early 120's all the time.
If this is a typical summer in Sac, we'll have 79 days above 90 degrees, 19 days above 100, and four days above 105! July on average is our hottest month. The record high here is 114 degrees.
