Three Consecutive Supermoons to Illuminate the Night Sky in Late 2025
A series of three consecutive supermoons will occur in October, November, and December 2025, offering skywatchers a rare celestial display.
In the final months of 2025, skywatchers will be treated to a rare sequence of three consecutive supermoons, occurring in October, November, and December. A supermoon happens when a full moon coincides with the Moon's closest approach to Earth, known as perigee, making it appear larger and brighter than usual.
The series begins with the Harvest Supermoon on October 7, 2025. Traditionally, the Harvest Moon is the full moon closest to the autumnal equinox, historically providing extra light for farmers during harvest season. On this date, the Moon will be approximately 224,599 miles (361,458 kilometers) from Earth, appearing about 7–9% larger and up to 15% brighter than a typical full moon.
Following this, the Beaver Supermoon will occur on November 5, 2025. This name originates from the period when beavers prepare for winter, and trappers set their final traps before the waters freeze. On this night, the Moon will be at its closest point to Earth for the year, approximately 221,817 miles (356,980 kilometers) away, making it the brightest supermoon of 2025.
The sequence concludes with the Cold Supermoon on December 4, 2025. This full moon signifies the onset of winter's cold and long nights. The Moon will be about 221,965 miles (357,219 kilometers) from Earth, appearing 7–8% larger and roughly 15% brighter than an average full moon.
Observers are encouraged to view these supermoons shortly after moonrise or before moonset, when the Moon appears largest near the horizon. Clear skies and minimal light pollution will enhance the viewing experience. The next occurrence of three consecutive supermoons will not happen until 2037, making this 2025 series a notable event for astronomy enthusiasts.
