Keep in mind that 1997/1998 and 2015/2016 were strong El Nino years. Also keep in mind that NOAA has been systematically “adjusting” the temperature record to make the past cooler so that the present looks warmer see here, here and here.
According to the National Weather Service for data through 2015, Tucson’s record high was 117 deg F on June 26, 1990, Phoenix reached 122 deg on the same day. Yuma’s high was 124 on July 28, 1995.
