As spring blooms in full swing, the May full moon, known as the Flower Moon, is set to grace the night sky on Monday, May 12, 2025. This celestial event, classified as a micromoon, will appear slightly smaller than usual, providing a unique opportunity for moon-gazers across the United States to witness its beauty.
The Flower Moon will reach its peak brightness at 11:56 p.m. CST, though it will be visible for several days around this date, according to NASA. This timing means that viewers can enjoy the sight of the full moon from May 11 through May 13, 2025. In Montgomery, Alabama, the moon will rise at 7:56 p.m. and set at 5:27 a.m. the following morning, while in Washington, D.C., moonrise will occur at 8:37 p.m., following sunset at 8:11 p.m.
The term "micromoon" refers to a full moon that occurs when the moon is at apogee, the point in its orbit farthest from Earth. As a result, the Flower Moon may appear 6% to 7% smaller than the average full moon, and about 12% to 14% smaller than a supermoon, which occurs when the moon is closest to Earth. Interestingly, the difference in size is subtle, and many viewers may not notice it unless specifically looking for it.
The origins of the name "Flower Moon" can be traced back to the Algonquin people, who named it to signify the blooming flowers that emerge across North America in May. Other traditional names for this full moon include the Budding Moon, Planting Moon, Egg Laying Moon, and Frog Moon, reflecting the various seasonal changes and animal activities that accompany spring. The Old Farmer's Almanac notes that these names draw from Native American, Colonial American, and European traditions, celebrating the natural world's revival.
In addition to its cultural significance, the Flower Moon serves as a reminder of the changing seasons. As the moon rises in the evening sky, many regions across the U.S. are expected to enjoy clear skies, particularly in California and parts of the Desert Southwest. However, some areas, especially in the Southeast, may experience cloud cover due to a slow-moving storm system. Despite this, many locations should have a stellar view of the moon, especially in areas with minimal artificial light.
For those planning to observe the Flower Moon, it's worth noting that the moon will appear larger when it first rises above the horizon, creating an optical illusion that enhances its beauty. As it climbs higher in the sky, its brightness will remain prominent, allowing viewers to appreciate its glow even if they miss the exact moment of peak illumination.
As the Flower Moon illuminates the night sky, it also marks the transition into summer for many, with the next full moon, known as the Strawberry Moon, set to occur on June 11, 2025. This name, like the Flower Moon, has its roots in Native American traditions, as it signifies the time when strawberries ripen and are ready for harvest.
For moon enthusiasts and casual observers alike, the Flower Moon presents a perfect opportunity to step outside and engage with the natural world. Whether you're in Alabama, Oklahoma, or Washington, D.C., the sight of this moon is a reminder of the beauty that exists just above us, waiting to be admired.
In summary, the May full moon, or Flower Moon, promises to be a captivating sight in the night sky on May 12, 2025. With its unique classification as a micromoon, it offers a rare chance to witness a full moon that may look a bit smaller than usual. As viewers prepare for this celestial event, they can also reflect on the rich cultural history behind its name and the seasonal changes it represents. So, mark your calendars and get ready to look up—nature's beauty is about to shine!
