Beaver Moon Is 2025's Biggest Supermoon

The Beaver Moon will peak as a supermoon on Nov. 5, 2025, reaching full illumination at about 8:19 a.m. ET (13:19 UTC) while near lunar perigee at roughly 221,817 miles (about 357,000 km), making it the closest and largest full moon of 2025. Because the full phase coincides with perigee, the Moon can appear noticeably larger and brighter—commonly cited as up to about 14% larger and 30% brighter than an average full moon. It is the second of three consecutive supermoons this season (Oct–Dec 2025) and will be followed by another Cold/December supermoon in early December. The Moon will be most striking to most observers around moonrise on the evenings of Nov. 4–5 (with Nov. 4–6 offering the best viewing window in many places) and will be visible worldwide, weather and local light pollution permitting. Viewers are advised to watch from dark, open sites to benefit from the horizon “moon illusion,” binoculars will enhance lunar detail, and coastal areas should expect modestly enhanced tidal ranges during the event.
