Names for the May Full Moon
The May full moon is commonly referred to as the Full Flower Moon. This name probably isn’t a surprise when you think of the saying: “April Showers bring May Flowers”. Welcome to Spring and the flowers that come with the season.
While the April full moon name doesn’t reference rain, the May full moon matches the time-honored saying.
Other nicknames for the May Full Moon include the Corn Planting Moon, and Milk Moon.
Will there be a lunar eclipse during the Flower Moon?
No, there will not be a lunar eclipse in May 2025. March and September will each have a Total Lunar Eclipse, also called a Blood Moon.
Will there a full supermoon during the full moon?
No, there will not be a full supermoon in May. The 2025 super full moons will be in October, November, and December.
A full supermoon is a full moon that nearly coincides with the closest point at which the Moon comes to Earth in its orbit, called perigee. The moon will have a larger-than-usual appearance. There isn’t an official definition of the exact distance the moon needs to be to be called a supermoon. It’s approximately 360,000 kilometers or closer, depending on the definition.
Will Flower Moon be a seasonal blue moon?
No, there will not be a blue moon in May, nor any other month in 2025. There was a seasonal blue moon in 2024 and there will be a blue moon in 2026 with a second full moon in May.
There are two definitions of blue moons. The most common, and the one you likely know, is when two full moons occur in the same month. The second full moon is typically called a blue moon.
The second definition relates to having an extra full moon on the calendar during a season. When a season has four full moons, the third full moon is also called a blue moon or a seasonal blue moon.
