Phoenix, Arizona, saw its 100th straight day of 100F (37.7C) heat this week.
The hottest large city in the United States broke its previous record of 76 consecutive 100F days set in 1993. The relentless streak, which started on 27 May and hit its 100th day on Tuesday, is forecast to persist into next week. An excessive heat warning is in effect through Friday, with temperatures expected to reach 110F (43C) tomorrow.
This summer was the hottest one in Phoenix since 1896, when records first began. Latest county data shows that at least 177 people died from heat-related causes so far this year, with 436 under investigation. Last year, Maricopa county saw 645 confirmed heat-related fatalities, enduring 55 days in a row with above 110F temperatures.

Yeah in Florida heat stroke/exhaustion is more likely because your sweating is less effective (less capacity to evaporate off the skin.
In Arizona dehydration complications (and then heat exhaustion/stroke) are more common because your sweat is so effective and evaporates so quickly that you almost don’t even realize. You can lose liters of water in a matter of a few hours. Then suddenly, the sweat stops and you die.
(another thing that gets missed is direct infrared intensity when in direct sunlight, which Arizona takes the cake).
