Stargazing in Phoenix, US
Phoenix's desert location gives it some of the clearest skies of any major US city, with over 300 clear nights per year. The city itself is Bortle 7–8, but the Sonoran Desert darkens rapidly outside the metro area. Flagstaff (2 hours north) is a designated Dark Sky City, and numerous dark-sky sites dot central Arizona. The dry desert air provides exceptional seeing conditions — Phoenix-area observers routinely resolve fine planetary detail. Monsoon season (July–September) brings afternoon thunderstorms but often clears by night.
