And Bobby knew this shit like 20 years ago. It regularly gets into the low 100s in July and August in that region. It's not so terribly bad since it's dry heat, especially when there is wind. Arizona isn't even the highest risk area. The biggest issue in the US wet-bulb temps in the southeast.
For people that aren't aware, wetbulb temps essentially measure how well you can cool yourself down by sweating. Humid air means sweating is less effective since it can't evaporate.
A wetbulb temp of 95°F (35°C) will kill someone in less than a workday if they're not given proper breaks.
A wet bulb temp of 35°C will kill a healthy person sitting still in front of a fan.
Yeah, any wetbulb above 30°C (86 °F) is potentially fatal without lots of rest breaks and water and shade and such. 35°C is unsurvivable - and not something that happens naturally on Earth.
Yet.
Wow, that is so cool!
