The Full Beaver Moon on November 5, 2025 will be a remarkable astronomical event, as it is expected to be the largest and brightest Supermoon of the year.
What is the Beaver Supermoon.
A Supermoon is defined as a Full Moon that occurs when our satellite is near perigee, which is the point in its orbit closest to Earth.
The Full Moon will occur on Nov. 5, 2025, reaching the peak of its full phase around 2:20 p.m. CET (Italian time), touching perigee around 11:27 p.m. “How strange,” you may be thinking, but although the culmination of the full phase is during the daytime, the spectacle will be best admired on the evening of Nov. 5 and also the evening before and after, when the Moon will still be almost fully illuminated and very close to perigee. So pack a blanket and get comfortable outdoors.
This combination of full Moon and perigee will make it the Full Moon with the largest apparent size throughout 2025. It will appear up to 7-8% larger and about 16% brighter than an average Full Moon. WoW!
Why it is called the “Beaver Moon”
As we have seen for previous Full Moon episodes, the names do not really have to do with what the Moon looks like (e.g., the pink Strawberry Moon does not exist). The name “Beaver Moon” comes from Native American traditions in North America. It refers to the time of year when beavers intensify the construction of their dams and prepare for winter by stockpiling food supplies. It was also the ideal time for hunters to set beaver traps before the swamps froze in order to procure furs for the cold months.
During the same period, it was also known as the Frosty Moon in reference to the drop in temperatures.
To admire it from Rome, we recommend you go to places with little artificial lighting; those who have houses in the country can observe it from the garden, but a balcony is fine too.
