Prime Viewing in Arizona: Cold Moon Supermoon Skywatching
Prime Viewing in Arizona
Arizona ranks second in the U.S. for witnessing December’s Cold Moon Supermoon, making it a top destination for skywatchers. Thanks to its dry desert air, low humidity, and minimal light pollution, the state offers some of the clearest winter night skies in the country. The December 4, 2025, supermoon will appear up to 14% larger and 30% brighter than usual, creating a breathtaking spectacle over Arizona’s iconic red rocks and desert landscapes.
Best Time and Tips
The peak illumination occurs around 5:14 p.m. MST, but the most vivid views happen at moonrise when the moon appears larger and more colorful near the horizon. For the best experience, head to open areas away from city lights and use a tripod for stunning photos. Arizona’s unique combination of elevation, frequent clear skies, and dark-sky regions ensures unforgettable lunar viewing this December.
