The Cold Supermoon, the third and final supermoon of 2025, will reach its peak less than an hour after sunset on the First Coast.
JACKSONVILLE, Fla. — The third and final supermoon of 2025 peaks Thursday, Dec. 4. This one is called the Cold Full Supermoon.
A supermoon occurs when the moon reaches its full phase while near perigee, the closest point in its orbit to Earth. The alignment makes the Moon appear larger and brighter than average, sometimes up to 30% brigther like we saw with the Super Beaver Moon in November.
The December full moon is traditionally known as the Cold Moon, a name rooted in early winter weather patterns in the Northern Hemisphere. When a supermoon and the seasonal Cold Moon fall on the same night, the event is often referred to as a Cold Supermoon.
For the Southeast, moonrise is expected just after 6 p.m. on Thursday, coinciding closely with the moment the Moon reaches its full phase. Specifically for Jacksonville it will be around 6:14PM. The timing means the Moon will appear especially large low on the eastern horizon, where atmospheric effects can make it seem even larger.
While weather conditions will vary across the southeast, skies should be clear enough to watch the moonrise. Check here for the latest forecast.
