I do not mind the heat, but ride mostly AM this time of year...sometimes PM for local errands.

Use a helmet (not required in New Mexico) mainly to keep sun off my head
A long sleeve light colored T shirt keeps sun off my arms.
Not as much issue with long traffic signals in central New Mexico as there was in Las Vegas, NV.

Attached photo is of my 2016 Moto Guzzi V7II, 4 PM, 21 June 2017 in Las Vegas.
The LCD display in the tach indicates 116 F (display while riding, not parked in sun)
I was only 70 then, but heat seems no different at age 76.
