Harvest Moon 2026: When and How to See It
Confirmed
In Short: The Harvest Moon will be visible in UK skies this weekend, reaching its fullest point on Saturday, September 26, 2026.
The Harvest Moon, known for its proximity to the autumn equinox, will be visible in UK skies this weekend, reaching its fullest point at 17:49 BST on Saturday, September 26, 2026. This full Moon, which traditionally marks the harvest season, will be visible as it rises over the horizon, potentially appearing yellow, orange, or reddish due to atmospheric conditions.
Many parts of the UK are expected to have favourable conditions for viewing the Harvest Moon, with the longest clear spells expected in the south and east. The current forecast suggests Saturday could bring some drier and brighter weather, particularly across parts of England, making it an ideal time for skywatchers to catch a glimpse.
The Harvest Moon gets its name from being the full Moon closest to the autumn equinox, which this year took place on Wednesday. Historically, the additional moonlight after sunset was useful to farmers gathering crops, as it extended their working hours.
The Royal Observatory Greenwich also lists the Corn Moon as another common name for this full Moon, reflecting the crops traditionally harvested around this time of year. However, it does not always fall in September, and if October's full Moon is closer to the autumn equinox, it takes the title instead.
When the Moon lies low in the sky and is close to the horizon, its light has to travel through more of the Earth's atmosphere before reaching our eyes, which can cause the Moon to appear yellow, orange, or even reddish.
In addition to the Harvest Moon, recent studies have shed light on the Moon's geological history. A new analysis of material returned by China's Chang'e-6 mission suggests that the Moon's nearside-farside dichotomy may trace back to enormous flows within the Moon's early magma ocean after it became tidally locked to Earth.
The Moon's surface continues to be a subject of scientific interest, with the discovery of a new crater that formed sometime between April 11 and May 22, 2024. This crater, spotted by Robert Wagner, a researcher on NASA's Lunar Reconnaissance Orbiter mission, is the largest new crater ever discovered in the solar system.
Unlike Earth, the Moon has almost no atmosphere, so space debris does not slow down or burn up before hitting its surface, making it a valuable site for studying impacts and understanding the Moon's geology.
Studying newly formed craters helps scientists understand the Moon's geology, which could help prepare future crewed missions to the Moon planned by both the United States and China.
