Isn't pretty much all of Mexico except for the coastal regions and Mexico City super hot during the summer. Most areas of Mexico have a similar climate to most of Arizona the Las Vegas region of Nevada and south east Texas very hot and dry during the summer. Its been super hot so far this year where I live in Fort Worth Texas is it will easily be the hottest year since 2011. Today it got up to 108 degrees Fahrenheit hopefully it was the hottest day of the year even though the hottest time of year takes place from July 27th to August 13th. Since its been super hot so far this year I pretty much only go outside early in the morning and during close to sunset and after sunset at night.
