It's about that time to write up goals for the coming year and reflect on the highs and lows of the last 12 months. What better time to ponder 2025's end than on the last full moon of the year? The dramatics will be in full swing as December's will appear brighter and fuller than usual.

A supermoon, described by NASA as one that occurs when the Moon is at its closest approach to Earth in its elliptical orbit (perigee), will rise on Thursday, December 4, according to Space.com. Supermoon "isn't an official astronomical term, but typically, it's used to describe a full Moon that comes within at least 90 percent of perigee," the agency explains on its website.

Seeing the glow of white light overhead is routine, but these types of Moons can be a rare sight to catch. They only happen three to four times a year, with past 2025 occurrences being in November and October.

A few elements set this planetary body's appearance apart. They can appear up to 14 percent bigger and 30 percent brighter than the faintest one of the year, NASA says.

Here's what to know about December's full supermoon, also known as the Cold Moon.


When is the December full supermoon 2025?

The Cold Supermoon will reach peak illumination on Thursday at 5:14 p.m. CT, per the Farmer's Almanac. Stargazers are urged to start looking for it at this time for the best view. This is because it will appear bigger since it's near the horizon, a phenomenon called "Moon illusion."

You'll want to grab a sweater before heading outdoors, as a cold front will swoop across South Central Texas the evening prior. It should be a chilliness worth braving, though. At its farthest, NASA's website cites that the moon is 252,088 miles away from Earth. However, this one will be only 221,813 miles from us, according to the agency.


Will the December full supermoon be visible in Texas?

The National Weather Service reports that San Antonio-area skies will be cloudy on Thursday. Onlookers in parts of town where the sky is clear should have no trouble seeing the supermoon.

Residents should find a dark environment that is shielded away from bright lights for the best viewing conditions.


Why is it called the Cold Supermoon?

The Cold Supermoon earns its name from the Farmer's Almanac, an American periodical that offers a different name for lunar events, passed down from generations of Native American, Colonial American, and European settlers.

The moniker comes from the fact that it's the season of frigid temperatures. Even the Lone Star State isn't exempt. Austin saw its coldest December 1 in decades, according to KXAN meteorologist Tommy House.

Some people also refer to the event as the Long Night Moon. This is "because it rises during the longest nights of the year, near the winter solstice, and remains above the horizon for an extended period," researchers at the Farmer's Almanac explain.
