The September Full Moon will peak as the Harvest Moon on Saturday, September 26, 2026 in the US. The name does not simply come from the month. The Old Farmer’s Almanac defines the Harvest Moon as the Full Moon closest to the autumnal equinox. In 2026, the September Full Moon meets that definition.
Why is it called the Harvest Moon?
The name comes from the way the Moon rises around the start of fall. Near the autumnal equinox, the Moon rises only about 25 to 30 minutes later on successive evenings in much of the northern United States. That gave farmers extra moonlight after sunset, allowing them more time to gather crops before nightfall.
The September Full Moon can also appear warm and golden near the horizon. Space.com explains that Earth's atmosphere can give the Moon a yellow-orange appearance when it sits low in the sky. The Moon can also look larger near the horizon because of the Moon illusion.
When is the Harvest Moon 2026?
The Full Moon reaches peak illumination at 12:49 p.m. EDT on September 26, or 4:49 p.m. UTC. Since that happens during daylight across much of the US, you will want to watch the Moon around sunset instead. The Moon will look full for several evenings around the peak.
