Harvest Moon 2026: In Alaska It Rises Earlier Each Night
Quick Reference: Harvest Moon 2026
- Full: Saturday, September 26, 2026, at 12:49 p.m. EDT
- Best viewing: Friday and Saturday evenings, at moonrise
- Why it is the Harvest Moon: it is the full Moon nearest the fall equinox
- Distance: 379,436 km, so not a supermoon this year
- The trick to watch for: the moonrise gap between nights, which shrinks the further north you are
The Harvest Moon is full at 12:49 p.m. EDT on Saturday, September 26. Because it fills out in the middle of the day, it will look full on both Friday and Saturday night. Either evening is worth stepping outside for.
It takes the name for one reason only: it is the full Moon that falls closest to the fall equinox. This year the equinox is on September 22 and the Moon is full four days later, which makes it a close match.
The Trick That Earned It the Name
On a normal night the Moon rises about 50 minutes later than it did the night before. Around the Harvest Moon that gap collapses. For several nights running, the Moon comes up at nearly the same time, just after sunset, and the old harvest day stretched on by moonlight.
The reason is geometry. In late September the Moon’s path meets the eastern horizon at a shallow angle, so a night’s worth of eastward travel costs it very little rising time. The shallower the angle, the smaller the gap. And the angle gets shallower the further north you go.
Your Moonrise Gap, by City
| City | Latitude | Gap between nights | Moonrise, Friday 25 Sep |
|---|---|---|---|
| Anchorage, AK | 61.2 | 2 minutes earlier | 7:20 p.m. |
| Seattle, WA | 47.6 | 17 minutes later | 6:29 p.m. |
| Minneapolis, MN | 45.0 | 19 minutes later | 6:32 p.m. |
| Toronto, ON | 43.6 | 20 minutes later | 6:35 p.m. |
| New York, NY | 40.7 | 23 minutes later | 6:13 p.m. |
| Denver, CO | 39.7 | 24 minutes later | 6:19 p.m. |
| Nashville, TN | 36.2 | 26 minutes later | 6:05 p.m. |
| Atlanta, GA | 33.8 | 28 minutes later | 6:55 p.m. |
| Dallas, TX | 32.8 | 29 minutes later | 6:45 p.m. |
| Miami, FL | 25.8 | 33 minutes later | 6:37 p.m. |
Miami waits 33 minutes between moonrises. New York waits 23. Anchorage does not wait at all: at 61 degrees north the Moon actually comes up about two minutes earlier each night. The effect that gave the Harvest Moon its name is strongest exactly where the growing season is shortest, which is a tidy piece of luck for anyone who ever had to get a crop in by hand.
How to Watch It
- Go out at moonrise, not midnight. The whole point is the Moon coming up while the sky still holds some light.
- Find an open eastern horizon. A field, a lake shore or a ridge facing east. Trees and buildings will cost you the best few minutes.
- Expect it to look orange and oversized. Low down you are viewing it through more atmosphere, which scatters the blue away. The size is an illusion your brain supplies for free.
- Try two nights running. Friday and Saturday both work this year, and comparing them is how you actually notice the short gap.

What the Almanac Does With a Harvest Moon
Tradition treats the full Moon as a time for finishing rather than starting. The waning days that follow are the old window for planting bulbs, garlic and root crops, and our Gardening by the Moon calendar narrows that down by task. The Best Days calendar does the same for household jobs.
This Harvest Moon falls in Aries, opposite the Sun in Libra. Our Harvest Moon horoscope takes that up sign by sign.
Frequently Asked Questions
When is the Harvest Moon in 2026?
It is full at 12:49 p.m. EDT on Saturday, September 26, 2026. Because it becomes full during daylight hours it will look full on both Friday and Saturday night.
Why is it called the Harvest Moon?
It is the full Moon that falls nearest the fall equinox, which in 2026 is September 22. The name comes from the extra evening light it gave farmers bringing in crops, because it rises close to sunset for several nights running.
Is the Harvest Moon a supermoon in 2026?
No. It is 379,436 kilometres away at the moment it is full, which is close to average. A supermoon needs to be nearer than about 361,885 kilometres.
Why does the Moon rise at almost the same time for several nights?
In late September the Moon’s path crosses the eastern horizon at a shallow angle, so a night of orbital motion delays its rising by much less than usual. Instead of the normal 50 minutes, the gap can fall to 20 minutes or less.
Is the effect the same everywhere?
No, and the difference is large. In 2026 the gap averages about 33 minutes in Miami, 23 minutes in New York and 19 in Minneapolis. In Anchorage it reverses: the Moon rises roughly two minutes earlier each night.
Why does the Harvest Moon look orange?
Because you are seeing it low in the sky, through a long slant of atmosphere that scatters blue light away and lets the reds and oranges through. It is the same reason sunsets are red, and it has nothing to do with the season.

Josh Morley grew up in Liverpool, where checking the sky before you leave the house is less a habit than a survival skill. He has spent his working life with data, and he came to the Farmers' Almanac by way of the thing the two have in common: the weather is the largest dataset any of us live inside, and most of us read it every day without noticing.
He writes the pieces here that come with a chart in them. All thirteen forces of the Beaufort wind scale, the soil temperature every vegetable actually wants, how to read a Kp number when you are out looking for the northern lights, and why the Harvest Moon rises earlier each night in Anchorage and later in Miami. Wherever he can he works the figures out rather than looking them up, from NOAA records or the JPL ephemeris, on the view that a date is only worth printing if you can say where it came from.
He has a soft spot for the old sayings that turn out to have real physics underneath them, and a habit of saying so when they do not.
