Imagine a moon so bright and close, it feels like you could almost touch it. Arizona is about to get front-row seats to exactly that! On December 4, 2025, the Cold Moon Supermoon will grace the Arizona sky, promising a celestial spectacle against the backdrop of the state's stunning landscapes. According to a new national study by Action Network, Arizona ranks a very respectable #2 in the U.S. for clear viewing of this lunar event. This means Arizonans are in for a treat they won't want to miss!

This particular Cold Moon is extra special; it's the grand finale of a rare triple supermoon event in 2025! Think of it as the lunar encore you didn't know you needed.
The Action Network's Supermoon Visibility Index took a deep dive into factors like sky clarity, humidity levels, elevation, and darkness across all 50 states to determine the best viewing locations. New Mexico snatched the top spot, but Arizona is right on its heels, boasting prime conditions for an unobstructed view.
An Action Network researcher explained, "Arizona’s desert atmosphere gives the Cold Moon incredible clarity. With dry air, big horizons, and vast dark-sky regions, the moonrise here feels especially vivid – and the odds of seeing it clearly are among the very best in the country." What makes the desert air so important? It's because moisture in the atmosphere can scatter light, making the moon appear hazy. Arizona's dryness minimizes this effect, allowing for a sharper, more brilliant view.
The December full Moon has traditionally been called the Cold Moon. This name signifies the arrival of winter, with its characteristically long nights. Many Indigenous cultures have names for this Moon that reflect the cold, the snow, the stillness, and the increasing darkness of the season. It's a time of reflection and anticipation, as the Earth prepares for a period of rest.
But here's where it gets controversial... Some people argue that the traditional names for the full moons are culturally insensitive and should be retired. Others believe that these names connect us to our history and the natural world. What are your thoughts?
So, what makes this Cold Moon a supermoon? Well, it's all about timing! The Moon's orbit around the Earth isn't perfectly circular; it's slightly elliptical. This means there are times when the Moon is closer to Earth (perigee) and times when it's farther away (apogee). When a full moon occurs around the time of perigee, we get a supermoon! It appears noticeably larger and brighter in the sky, especially when it's near the horizon at moonrise. This effect is amplified by something called the 'moon illusion,' where our brains perceive objects near the horizon as being larger than they actually are.
Adding to the drama, this Cold Moon follows November’s unusually small new Moon, creating a striking visual contrast. It's like nature's way of balancing things out. Furthermore, this Cold Moon will be one of the highest-rising full Moons in northern skies until 2042, making it even more visible and radiant. Talk about a lunar showstopper!
Why does Arizona consistently rank so high for stargazing? It all comes down to a perfect combination of factors:
- Dry desert air: As mentioned earlier, the lack of moisture reduces haze and allows for sharper views.
- Frequent clear nights in early winter: Arizona's winter weather is typically characterized by clear skies, providing ample opportunities for stargazing.
- Low humidity: Similar to dry air, low humidity contributes to clearer and more defined views.
- Extensive dark-sky zones: Arizona has made significant efforts to protect its night skies from light pollution, creating designated dark-sky zones where the stars shine brighter.
These conditions combine to make the Moon appear crisp, bright, and beautifully defined as it rises. Arizona truly offers some of the best conditions for skywatchers seeking a perfect viewing experience.
Looking for the best spots in Arizona to witness this celestial event? Here are a few suggestions:
- Sedona & Oak Creek Canyon: Imagine the red rock formations silhouetted against the backdrop of the rising Moon. It's a photographer's dream!
- Flagstaff Dark Sky Region: With its high elevation and minimal light pollution, Flagstaff offers unparalleled stargazing opportunities.
- Saguaro National Park: The iconic saguaro cacti provide a unique foreground for capturing stunning lunar images.
- The Superstition Mountains: The wide, dramatic desert horizons offer unobstructed views of the night sky.
- Outskirts of Phoenix or Tucson: Even just beyond the city limits, you can find pockets of dark skies that offer a respite from light pollution.
And this is the part most people miss... Don't forget to check the moonrise time for your specific location! This will vary slightly depending on where you are in Arizona.
Here's what you need to know to plan your viewing:
- Peak illumination: Approximately 5:14 p.m. MST on December 4.
- Best viewing: Around moonrise, when the Moon appears largest and most colorful.
- Tips: Choose an open horizon, avoid direct city lights, and use a tripod or stable surface for your camera to capture the best images.
For those curious, here are the top 5 states for viewing the Cold Moon in 2025, according to the Action Network study:
- New Mexico
