Ok. I googled and there is a recording of 54C in Death Valley in 2013. (There are other, hotter recordings but they’re all further back, like in the 1940s or 1920s, so the recorded are less reliable).

In any case, I can’t even begin to imagine what that would feel like.

Isn’t it temps in the 40s (Celsius) in Arizona when places have trouble taking off? Maybe I’m remembering wrong, but these high temps are scary to me.
