What September feels like
The worst of it eases late in the month and the evenings become survivable, though daytime is still a matter of planning rather than wandering. This is the quietest stretch on the calendar — if you want Badwater Basin to yourself at sunrise and you can handle the drive out, September will hand it to you.
Real rain shows up maybe one day all month; the rest stay dry. Most afternoons push past 90°.
