US EditionMay Will Have Two Full Moons, Including a Rare 'Blue Micromoon' Ending the Month. Here's What that Means.
Astronomy fans will see two full moons in May, including a Blue Moon at month’s end, Time and Date said.
- May 2026 brings two full moons to the calendar, beginning with the Flower Moon on Friday, May 1, and ending with a rare blue moon on May 31.
- The Flower Moon, linked to Algonquin tribes, references springtime's floral abundance, while a blue moon refers to the second full moon in one calendar month, not the moon's color.
- EarthSky reports both May full moons are "micromoons," occurring when the lunar body reaches apogee, its farthest point from Earth, making them appear smaller and dimmer than usual.
- Such double-moon events occur roughly every two to three years, and the next monthly blue moon will not appear until December 2028, making this May's occurrence notably rare.
- Despite the name, the moon will not appear blue, as actual blue-colored moons are exceptionally rare; National Weather Service meteorologists predict mostly cloudy skies for the May 1 peak in Indianapolis.
