Grand Canyon - Milky Way Forecast - US Southwest

This forecast tracks the conditions every astrophotographer needs: clear, moonless nights with exceptional atmospheric transparency. We combine cloud cover predictions with moon phase, lunar position, and visibility data to identify your best Milky Way shooting opportunities.

The American Southwest offers some of the darkest skies in the developed world. Many of these locations hold International Dark Sky Park designations, meaning active protection of their exceptional night sky quality.

What makes the Southwest special for astrophotography:

• Exceptional darkness - Death Valley and Big Bend rank among the darkest places in North America
• Dry climate - Low humidity means better atmospheric transparency and seeing conditions
• Iconic foregrounds - Arches, hoodoos, mesas, and desert landscapes create unforgettable compositions
• Altitude advantage - Many locations sit above 5,000 feet, reducing atmospheric interference

The Milky Way core is best visible from March through October in the Northern Hemisphere. For the most dramatic shots, plan around new moon phases and arrive well before astronomical twilight ends. Summer months offer the Milky Way core high overhead, while spring and fall provide lower-angle views perfect for wide landscape compositions.
