Cold Supermoon - Thursday, December 4th

The 'grand finale' of the 2025 lunar cycle, the last of four total supermoons this year, will take place on Thursday, December 4th and is as rare as it will be bright. Experts are predicting that the moon will 'hang low, look huge, and glow brighter than usual' this due to a moon illusion, which is an optical effect.

USA Today reports that peak illumination will happen at approximately 6:15pm on Thursday.

This full 'cold moon,' will be the third and last of the year and is expected to orbit 221,965 miles from Earth. It will appear full on both Wednesday and Friday nights as well. If weather permits, this visual spectacle will make it perfect for catching photos or simply admiring a gorgeous autumnal evening sky.

Full Moon Vs. Supermoon

Though there are always a number of full moons each year (12 typically, but every 33 months we'll get an extra for a total of 13), the Supermoon is something a bit different. When a full moon coincides with the moon's closest point to earth, it appears larger and brighter than a standard full moon, deeming it 'Supermoon status.' Because of this, it will seem 14% bigger and 30% brighter to those watching from the ground.

The unique part of the December 4th Supermoon is that, according to the Old Farmer's Almanac, it will be higher in the sky than any other full moon until 2042. Though there will be three supermoons in 2026, none will be quite as bright nor appear so close.

The third and final supermoon of the year, the December 'cold moon' is said to appear full on both Wednesday and Friday nights as well, and expected to orbit 22,965 miles from Earth.
