The Guardian recently published a photo set matching far infrared images of Phoenix with ordinary photographs.
The images were taken by Carlos Barria, using a Flir thermal camera, which also shows a point temperature (in Fahrenheit).
It's an interesting set, taken in late July 2023 and which "reveal a Phoenix where concrete on the street registers 150F (66C), outdoor workers’ bodies reach 105F (41C) and homeless people swelter, surrounded by surfaces as hot as 143F (62C)" and it's unusual to see visual and thermal images matched in this way: you can swipe between the two.
