For some perspective, since this seems to be on the sensational side, the yearly average high for August is 117, with temperatures routinely reaching into the 120s, with similar reports found through the last decade (on mobile, can’t reference easily).
So it's not a record temperature, just a really hot temperature in a place that routinely sees really hot temperatures?
If Iran's anything like Europe (and I truly have no idea if it is) then the real heat won't hit until July.
