December's full moon
Cold Moon 2026
The Cold Moon is December's full moon. In 2026 it is full on Thursday, 24 December 2026, 01:28 UTC. It is named for the long, cold nights of December, when the full moon rides highest and longest in the sky.
Cold Moon meaning
December's full moon is named for the cold that settles in around it, and in Europe for the long nights it lights: the full moon nearest the winter solstice stays above the horizon longer than any other in the year.
Also called: Long Night Moon, Oak Moon, Moon before Yule. The names come from the seasonal calendars of Native American, Colonial American and European tradition, as collected in the Old Farmer's Almanac; each one marks what was happening on the land in that month.

Best time to see the Cold Moon
Go out at moonrise on the evening of Thu 24 Dec: look east just after sunset, when the Moon sits on the horizon, looks largest, and takes on its warmest colour. The Cold Moon is up for the longest stretch of the year in the north, from early evening to late morning, on the highest track across the sky.
