If you’ve been looking for a reason to spend more time outside this fall, the night sky has one for you. The Harvest Moon, one of the most recognizable full moons of the year, will light up the sky later this month.
The 2026 Harvest Moon will reach peak illumination on Saturday, September 26, at 12:49 p.m. EDT, according to The Old Farmer’s Almanac. However, it will appear full and bright for three days, if the weather is clear.
What is the Harvest Moon?
The Harvest Moon isn’t always tied to a specific month. Instead, it’s the full moon that occurs closest to the autumnal equinox, which marks the beginning of astronomical fall in the Northern Hemisphere. This year, the equinox falls on September 22, making September’s full moon the Harvest Moon. In some years, the October full moon is closer to the equinox and takes the title instead.
The name has a practical history, too. Around the fall equinox, the moon rises only about 25 to 30 minutes later each night in the Northern Hemisphere, rather than the usual 50 minutes. Because the moonrise time changes so little from one night to the next, the moon can appear relatively soon after sunset for several evenings in a row.
Before electric lights and modern farm equipment, that additional moonlight could give farmers more time to gather summer crops. Hence, the name "Harvest Moon."
How to see the Harvest Moon
You don't need any special equipment to enjoy the Harvest Moon. For the best view, find a spot with a clear, unobstructed view of the eastern horizon and head outside around moonrise. The moon can also appear especially large and golden when it’s close to the horizon, thanks in part to the well-known “moon illusion.”
Happy viewing!
