Cold Moon: The Last Full Moon of 2025

The last full moon of the year, called the “Cold Moon,” will illuminate the sky on December 4th, reaching its maximum at 23:14 UTC.

This is also the last supermoon of 2025. Supermoons occur when a full moon coincides with perigee (the closest point of the Moon's orbit to Earth), making it appear larger.

Definition of Supermoon: NASA explains that “supermoon” is used for a full moon that falls within at least 90% of the distance to perigee.

Other Names for the Cold Moon: Also known as the “Long Night Moon,” the Cold Moon follows the Harvest Moon (October) and the Beaver Moon (November).

Spiritual Significance: The Cold Moon is considered a symbol of turning inward, reflection, and quiet inner growth.

How to Observe the Cold Moon

The full moon will remain visible throughout the night.

Best Time: Immediately after moonrise (appears larger near the horizon).

Best Place: Away from city lights, with an open horizon.

Necessary Equipment: Not required, but a telescope or binoculars can help. Dress warmly and bring something to eat or warm drinks.
