The Flower Moon reaches its full phase this evening – on Friday, May 1, 2026. For star-gazers in the UK, it is expected to be fully illuminated at 6.23pm BST. It will climb across the southern sky throughout the night before setting around dawn.
This year’s event is a “micromoon,” occurring because the moon is near its “apogee”, which is the furthest point from Earth in its elliptical orbit. Consequently, the Moon will appear slightly smaller and dimmer than a typical full Moon, though the visual difference is often subtle to the naked eye.
The name “Flower Moon” originates from Native American seasonal traditions, later popularised by the Farmer’s Almanac. It signifies the time of year when flowers bloom in abundance across the Northern Hemisphere, marking the definitive arrival of warmer weather and longer daylight hours.
The moon will first appear low on the eastern horizon as daylight fades. Clear skies and breaks in cloud cover will provide the best viewing opportunities for star-gazers across the UK.
Beyond its astronomical properties, the Flower Moon is one of several traditional lunar names linked to nature’s cycles. In the UK, it specifically coincides with the blooming of woodland bluebells and hawthorn blossoms, serving as a seasonal marker for the peak of spring.
