As the year comes to a close, skywatchers are in for a special treat: the December 2024 full moon, often referred to as the “Cold Moon.” This moon, marking the last full moon of the year, is traditionally associated with the long, chilly nights of December.
But in 2024, it will offer something even more intriguing—a surprising and unique shape that could catch the eye of both casual observers and seasoned stargazers alike.
While the full moon is always a spectacular sight, the December 2024 Cold Moon stands out for several reasons. From its appearance to the celestial events surrounding it, this full moon promises to be a sight worth seeing. Let’s take a closer look at what makes this particular Cold Moon so unique.
What is the ‘Cold Moon’?
Before diving into the specifics of the December 2024 Cold Moon, it’s important to understand the history behind this name. The full moon that occurs in December has long been associated with the onset of winter, particularly in the Northern Hemisphere. As the days get shorter and the nights grow colder, this moon is a reminder of the harsh winter conditions that are now settling in.
The term “Cold Moon” was coined by Native American tribes to reflect the frigid temperatures of the season. Other cultures and traditions also have their own names for the December full moon, but “Cold Moon” has become widely recognized.
The Surprising Shape of the December 2024 Cold Moon
What makes the December 2024 Cold Moon stand out this year is the unique shape it will take when viewed from Earth. Most full moons appear as a perfect, round disc in the sky, but due to the moon’s elliptical orbit, its size and shape can appear to change slightly over time. This phenomenon, known as the “moon illusion,” will be particularly noticeable during the December 2024 Cold Moon.
In 2024, the full moon will occur when the moon is at its perigee—the closest point in its orbit to Earth. This will cause the moon to appear slightly larger and brighter than usual, making it a so-called “supermoon.” However, what sets this Cold Moon apart is the fact that it will also appear slightly oval in shape rather than perfectly circular. This is due to the angle at which it will be observed and the interplay of various optical illusions, such as the atmosphere’s distortion and the moon’s path across the sky.
This subtle change in shape adds a fascinating twist to the usual full moon display. The oval appearance will likely be most noticeable when the moon is near the horizon, where it can appear stretched out due to the atmosphere’s effect on light. As the moon rises higher in the sky, it may return to a more typical round shape, but that brief moment near the horizon promises to be a striking sight for anyone observing.
A Celestial Show: The Cold Moon and Other December Events
In addition to its surprising shape, the December 2024 Cold Moon will also be accompanied by a few celestial events that will make this full moon even more captivating. For example, stargazers can expect to see the Cold Moon coincide with the peak of the Geminid meteor shower, which is known for producing some of the brightest meteors of the year. This will add a shimmering backdrop to the moon’s already impressive display.

Find a location with minimal light pollution for the best experience. A spot with a clear view of the horizon will allow you to witness the moon’s oval shape as it rises, adding to the awe of the event. Keep in mind that the moon’s appearance will be influenced by the atmosphere, so the most dramatic view will occur when the moon is lower in the sky.
