September full moon 2026: Here's when and where to watch

The September full moon, traditionally known as the Harvest Moon, is set to illuminate the night skies on September 26, 2026, reaching peak illumination at 12:49 p.m. EDT.

The Harvest Moon will appear in the eastern sky shortly after the sun sets on September 26 and will be visible in the constellation of Pisces. The moon will appear to have an unusual yellowish-orange hue due to the Rayleigh scattering effect as it rises into the sky.

The timings will differ according to location: for example, in New York it will occur at 12:49 p.m., for Londoners it will be at 5:49 p.m., and for those who live in Beijing and Tokyo it will happen on the morning of September 27.

Why it’s called the Harvest Moon

The full moon earned its name as it falls closest to the September equinox, the astronomical start of autumn in the Northern Hemisphere. Before artificial lighting, farmers used to rely on extra moonlight to harvest their crops before sunset.

The moon’s unique orbital path creates a shallow angle with the horizon, leading to rise at nearly the same time on successive nights, offering extended evening illumination.

Additional treat for skywatchers

Saturn will be seen alongside the Harvest Moon, shining brightly with a yellow colour right below the moon’s disc. Jupiter and Mars will also be visible to early morning risers, while Venus will be most radiant on September 18.

The equinox in September takes place on September 22 at 8:05 p.m. EDT, which signals not only seasonal changes but also a forecast of more frequent aurora sightings in the north.

There is no need to use any additional gadgets to observe this astronomical phenomenon; a clear view of the eastern sky is enough.
