Cold Moon: The last—and brightest—supermoon of 2025 arrives December 4
Get ready for the Cold Moon, the final full moon and last supermoon of 2025, peaking on December 4 at 23:14 GMT.
This one's a big deal—it'll be the most "extreme" full moon until 2042, looking extra large and bright since it's so close to Earth.
When and where to catch it
The Cold Moon will look full from December 3 to 5, but your best shot is around moonrise on December 4.
If you're in the Northern Hemisphere, this will be the highest full moon of the year; in the Southern Hemisphere, it's actually the lowest.
For a great view, head somewhere dark and away from city lights.
What else to watch for
No fancy gear needed—the Cold Moon is easy to spot with just your eyes. But if you have binoculars or a telescope handy, you'll catch even more detail.
Look out for nearby sights like the Pleiades star cluster, Pollux, plus Jupiter lighting up the winter sky.
It's a perfect night for anyone who loves stargazing before the next full moon on January 3, 2026; the next supermoon will not occur until November 24, 2026.
