Will Michigan experience the supermoon tonight? The cold moon may be hidden

Stargazers in Michigan may have a chance to catch the year's final "supermoon" on Thursday evening, Dec. 4, though winter conditions might limit visibility for some residents. This supermoon, often called the "cold moon," is set to reach its peak at 6:14 p.m. EST and marks the third consecutive full supermoon of 2025, according to the Old Farmer's Almanac.

When it rises along the eastern horizon, the supermoon is expected to appear larger and brighter than usual full moons, creating the well-known moon illusion.

Peak Timing for the Cold Moon

The cold moon will be at its fullest and closest point at 6:14 p.m. on Dec. 4.

Visibility Across Michigan

Some areas of Michigan may struggle to see the supermoon due to clouds and snow. Southern and eastern regions have a better chance for a clear view. Here's a brief forecast for several cities:

• Sault Ste. Marie: Snow and wind expected throughout the day and night.
• Marquette: Cloudy with a chance of snow and blowing snow overnight.
• Gaylord: Mostly cloudy skies tonight.
• Traverse City: Mostly cloudy, with possible snow overnight.
• Holland: Mostly cloudy, occasional snow possible.
• Lansing: Partly cloudy overnight.
• Detroit: Mostly clear skies overnight.

Understanding the Supermoon

The cold moon qualifies as a supermoon, which occurs when a full or new moon coincides with its closest approach to Earth in its orbit. At this point, the moon can appear up to 14% larger and 30% brighter than typical full moons.

Origin of the Cold Moon Name

The term "cold moon" reflects the chilly weather of the season and comes from the Mohawk people, according to the Old Farmer's Almanac.

Moon Distance from Earth

The average distance from Earth to the moon is 238,855 miles. The moon slowly drifts away each year, though this change is not noticeable. At its farthest (apogee), it can reach 252,088 miles, while at its closest (perigee), it comes within 221,817 milesthe distance of this year's closest supermoon.

Next Supermoon

The next supermoon, known as the "wolf moon," is expected on Jan. 3, 2026.

The Moon Illusion

The moon illusion occurs during moonrise and moonset, making the supermoon look even larger than usual. While the phenomenon is well-known, scientists still do not fully understand why our brains perceive the moon as bigger when it is near the horizon.

Despite centuries of observation, the moon illusion remains a fascinating mystery that continues to captivate skywatchers.

Analysis: December’s Final Supermoon – A Phenomenon Shaped by Weather and Perception

The final supermoon of 2025, also known as the "cold moon," promises to be an extraordinary celestial event. However, the weather conditions in Michigan may pose a challenge for many residents hoping to catch a glimpse of it. As with any astronomical event, visibility plays a crucial role, and in this case, clouds and snow could obscure the supermoon in some regions.

At 6:14 p.m. EST on December 4, the cold moon will reach its peak, becoming the third consecutive full supermoon of the year. This is an especially rare occurrence, and it’s worth noting that the supermoon will be 14% larger and 30% brighter than typical full moons. Yet, despite these impressive statistics, only a few lucky viewers in southern and eastern Michigan may get the best viewing conditions, as other areas face overcast skies or snow showers.

While the weather may limit how many people experience the full spectacle, the supermoon itself remains a fascinating astronomical occurrence. The supermoon happens when the moon reaches its closest point to Earth, known as perigee. This explains why it appears so much larger and brighter. The “cold moon” name, derived from the Mohawk people, adds a layer of cultural context to the event, linking it to the colder season.

The supermoon also brings attention to the mysterious moon illusion that causes the moon to appear larger when it rises on the horizon. Though scientists continue to study this phenomenon, the illusion remains an unsolved curiosity that fascinates skywatchers around the world.

Ultimately, December’s cold moon presents a chance to appreciate both the beauty of nature and the complexity of our perceptions. Even if some parts of Michigan face challenging weather, this event is worth marking on the calendar—especially for those with clear skies and a passion for stargazing.
