December Supermoon 2025: Skywatchers are set for a striking celestial moment this week as the final full moon of the year, known as the Cold Moon, lights up the night sky. This December Cold Moon is a supermoon, shining brighter and appearing larger because the moon travels close to its perigee.

Why December’s Full Moon Is Called the Cold Moon?

The name Cold Moon comes from the sharp drop in temperatures across the Northern Hemisphere as winter approaches. It is also called the Moon Before Yule, marking the last full moon before Christmas and the closing lunar event of the year.

When to Watch the Cold Moon

The Cold Moon will rise on December 4, 2025. With the moon passing within 90 percent of its closest point to Earth, it may appear up to 30 percent brighter than the year’s smallest full moon. This makes it one of the most visually impressive supermoons of 2025.
