“Supermoon” Over GTA! December 4, 6:14 P.M. EST

Torontonians, don’t miss this opportunity! You will have just one chance to witness the Final Supermoon of 2025, the third one this year and the last until November 2026.

It almost sounds like the title of a sci-fi movie. But what’s the story behind it?

The Story: Like many folk tales and campfire stories, the concept of a “Supermoon,” also called “The Cold Moon,” combines scientific facts with cultural myths.

Scientifically, a supermoon occurs when a full moon is at its closest point to Earth in its orbit, known as perigee. This proximity causes the moon to appear larger and brighter than usual. The term “supermoon” was coined by astronomer Richard Nolle, who defined it as a full moon that comes within 224,641 miles of Earth.

While the scientific explanation is precise, there are also myths and legends associated with supermoons. These folklore tales often suggest that supermoons could trigger extreme natural events, influence human behaviour, and, most intriguingly, bring good luck. Such myths have endured across cultures and time, often linked to the moon’s impact on emotions, fertility, and even supernatural occurrences.

Known by various names—including “Supermoon,” “Cold Moon,” “Snow Moon,” “Winter Maker Moon,” and “Moon When The Deer Shed Their Antlers”—this event marks the third and final supermoon of the year, concluding 2025 with a stunning display in the night sky as we head into 2026.

This week’s supermoon will be the last of the three to occur this fall, and it won’t be seen again until November 2026. It will reach its peak at 6:14 P.M. EST on December 4, as confirmed by both NASA and The Almanack (Almanac in the US).
