Full Moon September 2027: The Harvest Moon

The September 2027 full Moon, the Harvest Moon, is on Thursday 16 September 2027 at 00:04 BST. It rises at about 19:00 in London, 19:05 in Birmingham and 19:05 in Edinburgh that evening, and looks full to the eye the night before and the night after. For the one coming up next, whatever the month, see when is the next full moon.

Why is the September full Moon called the Corn Moon?

The Corn Moon is named for the corn harvest; the full Moon nearest the autumn equinox is the Harvest Moon. The names are folklore rather than astronomy: most come from the Algonquian peoples of north-eastern North America, were adopted by colonial settlers and were popularised by the Maine Farmers' Almanac from the 1930s onwards. September and October are the awkward pair: the Harvest Moon is whichever full Moon falls nearest the autumn equinox, and the Hunter's Moon is the one after it, so in some years the names shift by a month. Our full moon names guide covers all twelve and the blue moons and supermoons that sometimes join them.

Full moon September dates: 2026 to 2028

The Moon takes 29.5 days to go from one full Moon to the next, so each year's September full Moon falls about 11 days earlier than the year before, then jumps forward again once a thirteenth full Moon has squeezed in.

The September full Moon in the UK sky

September's full Moon is usually the Harvest Moon, the one nearest the autumn equinox. Around the equinox the Moon rises only 20 to 30 minutes later each night instead of the usual 50, which is where the harvest story comes from: several bright moonlit evenings in a row.

Is the September 2027 full Moon a supermoon?

No. At the moment it is full the Moon is about 399,322 km from Earth, outside the nearest tenth of the Moon's distance range (about 361,500 km), the rule this site uses for a supermoon. The next supermoon is the Beaver Moon on 24 November 2026. Distances come from the same lunar calculation as the dates above; a supermoon is a matter of definition, not a different kind of Moon.

How to see and photograph the Harvest Moon

• Watch it rise. Face east ten minutes before the moonrise time above, with a low horizon. Near the horizon the Moon looks enormous (the Moon illusion) and often deep orange.
• Look the night before or after if you want detail: at full the Moon is flat and shadowless, but a day either side the terminator returns and craters along it throw long shadows. Our Moon page says what to look for.
• Photograph it with a phone on a tripod or any camera: a moonrise over a landscape is the easiest astrophoto there is. Settings are in our guide to photographing the Moon.
• Save the faint stuff for new Moon. A full Moon washes out the Milky Way, galaxies and all but the brightest meteor showers; the darkest week of the month is around the new Moon, listed on our moon phase tonight page.
