The upcoming Flower Moon will officially peak on May 1, 2026, at 10:23 am PST. This full moon, named for the blooming flowers of spring across North America, will also be a micromoon—appearing smaller than usual due to its distance from Earth.
The Flower Moon will reach an impressive 99% illumination on the nights of May 1 and May 2. At its peak, it will be 100% illuminated at precisely 1:23 p.m. EDT. By comparison, the average full moon measures about 31 arcminutes in size; during this micromoon phase, it will only measure around 29.72 arcminutes. This slight difference can make it harder to notice unless you’re keenly observant.
That context matters because many people look forward to lunar events like this one for various reasons—whether it’s for photography, romantic evenings, or simply enjoying nature’s beauty. The Flower Moon is particularly special as it marks the transition into spring when flowers begin to bloom across North America.
In addition to the Flower Moon, May will feature another full moon later in the month—a Blue Moon—set for May 31. Blue Moons occur when there are two full moons in a single calendar month and happen every two to three years. The last Blue Moon was a blue supermoon in August 2024.
Skywatchers can expect clear views of this lunar event by looking towards the southeast horizon after sunset at around 7:26 pm PST. Notable celestial companions during this event include Venus and Jupiter, which may enhance the viewing experience.
The Old Farmer’s Almanac notes that “the flower moon’s name comes from the fact that the full moon coincides with flowers blooming in the spring across North America.” This connection highlights how natural phenomena often intertwine with cultural traditions and seasonal changes.
Catherine Pilachowski emphasizes that “the first full moon of the month, known as the flower moon, reaches peak fullness at 1:23 p.m. ET on May 1.” As excitement builds for this unique astronomical event, many hope to capture stunning images or simply enjoy the sight with loved ones.
The Flower Moon is not just another full moon; it’s a reminder of nature’s cycles and beauty. Mark your calendars for May 1 and prepare for a night under the stars.
