Dawg, y'all and your namby-pamby Euro temps can gone-head and sit down somewhere.
Temps in Phoenix during the summer can regularly hit over 115 in the summers and peak at 120 (Seville could never) and thanks to the monsoon season (~July - September) you can also see humidity as high as 60%.
@Young_Chitlin and
@Bender Rodriguez can attest to this.
Temps in Vegas can easily hit 110 and will sit at 110+ for days or even weeks on end and top out around 118 in the summer and since it also gets a monsoon season around the same time, you also get humidity that can land between 30-50%.
@Turf knows what I'm talmbout.
