This October, the night sky will showcase a stunning celestial event: the Harvest Supermoon, the largest and brightest full moon of 2025. Mark your calendars for Monday, Oct. 6, when this remarkable phenomenon reaches its peak at 11:47 p.m. Eastern time. As it rises low on the horizon, the moon will glow with a brilliant golden hue, casting a magical light across the autumn landscape.
The Harvest Moon holds a special place in the hearts of skywatchers, photographers, and gardeners alike. Unlike any other full moon, it happens to be the first supermoon of the year, making it an event not to be missed. Supermoons occur when the moon reaches perigee, its closest point to Earth, making it appear up to 14% larger and 30% brighter than the average full moon. In 2025, this extra luminosity makes the Harvest Supermoon an unforgettable sight.
What Makes the Harvest Moon Unique?
The Harvest Moon is the full moon closest to the autumnal equinox (Sept. 22 or 23). Historically, its additional light provided farmers with extra hours of evening illumination to complete their harvests before the first frost. This natural gift of light continues to inspire awe and admiration today, as it rises at nearly the same time for several nights in a row, offering extended twilight hours.
In 2025, October’s full moon takes the title of the Harvest Moon, as it occurs closer to the equinox than September’s full moon. While September’s moon is called the Corn Moon, October’s moon is heralded as the "harvest" moon, marking the crucial time when the harvests are in full swing.
Viewing Tips for the Best Experience
To fully appreciate this celestial wonder, head to an open space such as a park, field, or waterfront, where the moon will appear even more spectacular. For the most dramatic effect, try to view the moon just as it rises or sets—its proximity to the horizon will make it appear larger and more awe-inspiring.
Photography enthusiasts will find this an ideal time to capture the moon’s glowing beauty. Use a tripod for sharp images and incorporate foreground objects, such as trees or buildings, to give the moon added scale. Adjust your exposure settings to strike a balance between the moon’s bright light and the darker details around it.
Why This Supermoon Is a Must-See
This Harvest Supermoon is not only the first of three supermoons in 2025, but it’s also a visual treat. The moon will seem to glow larger and brighter than any full moon earlier in the year, making it a prime opportunity for photographers and stargazers to create breathtaking lunar landscapes.
If you’re planning to observe this cosmic event, make sure to check your local time for moonrise and moonset using the Almanac’s Moonrise and Moonset Calculator. The supermoon will be visible well before and after its peak, so you’ll have plenty of time to witness its awe-inspiring beauty.
A Celestial Tradition
The Harvest Moon has been named and celebrated in various cultures for centuries, each giving it a unique significance. Some traditions mark the time for hunting, as the full moon provides a bright night to track animals. Others see it as a time for agricultural rituals and seasonal changes. For many, the Harvest Supermoon is a symbol of abundance and transition, connecting modern observers to ancient customs.
As the largest and brightest supermoon of 2025, this event will surely captivate all who take a moment to witness its beauty. So, whether you’re a stargazer, photographer, or simply someone who enjoys the mysteries of the night sky, the Harvest Supermoon promises to deliver a spectacular show that is not to be missed.
