September's full moon

The Harvest Moon

The full moon closest to the September equinox — famous for rising near sunset several nights running, lighting the harvest. The lore and how to see it.

Short answer
The Harvest Moon is the full moon nearest the September equinox — usually September's. Its trick: it rises only a little later each night, so for several evenings a bright moon appears soon after sunset — light that once let farmers harvest into the night.

When is the Harvest Moon?

In 2026 the Harvest Moon peaks on September 26 at 16:49 UTC (12:49 PM EDT / 9:49 AM PDT) — a supermoon. In 2027 it falls on September 15.See 2026 calendar

Why "Harvest"?

Unlike the other moons, the Harvest Moon is named for an event, not a month: it's the full moon closest to the autumn equinox. Around this time the Moon's orbit meets the horizon at a shallow angle, so it rises only ~25 minutes later each night instead of ~50 — giving farmers several evenings of bright early moonlight to bring in the crops.

What it looks like

For a few nights running, the Harvest Moon rises big and golden right around sunset in the east. The warm colour is the usual horizon effect — extra atmosphere reddening the low Moon — amplified by the 'moon illusion' that makes a horizon Moon look huge.

2026: the first supermoon of the year

The 2026 Harvest Moon is a supermoon — a full moon occurring near perigee, the closest point of the Moon's orbit — and it opens a run of three consecutive supermoons that closes out 2026 (September, October, November). A perigee full moon looks up to about 14% larger and 30% brighter than one at apogee; the difference is subtle to the naked eye, but a supermoon rising at sunset during harvest weeks is the Moon at very close to its most imposing.

Fullness comes at 16:49 UTC on September 26 — around midday in the Americas — so both the nights of September 25–26 and 26–27 are effectively full, with moonrise near sunset each evening.

Three days after the equinox

The 2026 edition earns its name with room to spare: the September equinox falls on the 23rd and the full moon follows less than four days later — about as close as the pairing gets. That proximity is what powers the Harvest Moon's party trick: with the Moon's path nearly flat against the evening horizon, moonrise slips only ~25 minutes later per night instead of the usual ~50, delivering several consecutive dusks with a huge amber moon climbing in the east. Before electric light, those evenings genuinely extended the workday of the harvest — the name is agricultural economics, not poetry.


Frequently asked questions

Why does the Harvest Moon rise at almost the same time for several nights?
Near the September equinox the Moon's path makes a shallow angle with the horizon, so it rises only about 25 minutes later each night instead of the usual 50 — several evenings of early moonlight.
Is the Harvest Moon always in September?
Usually, but not always — it's the full moon nearest the autumn equinox, so about once every three years October's full moon is closer and takes the name instead.
When exactly is the Harvest Moon in 2026?
It reaches fullness on Saturday, September 26, 2026 at 16:49 UTC — 12:49 PM EDT / 9:49 AM PDT — just under four days after the September 23 equinox, and it is a supermoon.
Is the 2026 Harvest Moon a supermoon?
Yes — it is the first of three consecutive supermoons ending 2026 (September, October and November). A supermoon is a full moon near perigee, appearing up to ~14% larger and ~30% brighter than a full moon at apogee.
