As twilight falls on November 5, 2025, the night sky will dazzle with the year’s most stunning lunar spectacle — the Beaver Supermoon. This celestial event, set to reach its peak illumination at 8:19 a.m. ET, will mark not only November’s full moon but also the closest full moon to Earth in all of 2025, according to NASA and the U.S. Naval Observatory.
Often called the Beaver Moon, this full moon gets its traditional name from the time when beavers prepare their lodges and store food for winter. Historically, November also marked the season when trappers set out to gather beaver pelts, prized for their thick winter coats.
Why It’s a Supermoon
A supermoon occurs when the moon’s orbit brings it closest to Earth — a point called perigee. During this phase, the moon can appear up to 14% bigger and nearly 30% brighter than a typical full moon. In November 2025, the lunar distance will shrink to around 221,817 miles from Earth, making it the most luminous and largest moon of the year.
However, this striking size difference is often enhanced by perception — an optical illusion that occurs when the moon rises near the horizon and appears larger compared to surrounding objects.
Best Time and Place to Watch
Skywatchers can experience the Beaver Supermoon across the world under clear skies. To get the best view, experts recommend stepping outside soon after moonrise or just before moonset.
New York: Sunset at 4:47 p.m. EST, Moonrise at 5:19 p.m. EST (Nov 6)
Los Angeles: Sunset at 4:56 p.m. PST, Moonrise at 4:57 p.m. PST (Nov 6)
London: Sunset at 4:24 p.m. GMT, Moonrise at 5:06 p.m. GMT (Nov 7)
For optimum visibility, find a spot away from bright city lights, allow at least 15–20 minutes for your eyes to adjust, and check weather and astronomy apps for localized moonrise times.
The Cultural and Astronomical Meaning
Across cultures, November’s full moon symbolizes reflection, completion, and preparation for the winter months. In Native American traditions, it signifies nature’s cycle of storing energy and resources before the cold season sets in. For astronomers, this supermoon presents a rare chance to study the moon’s surface and brightness variations in closer proximity than usual.
What’s Next in the Lunar Calendar?
If cloudy skies hide this cosmic show, mark your calendars for the next celestial appearance — the Cold Moon — expected on December 4, 2025.
The November Beaver Supermoon offers more than just beauty; it’s a reminder of the harmony between Earth and its closest celestial neighbor, lighting up the skies and inspiring awe around the world.
