Here’s the latest on May 2026 full moons.
- May 1, 2026: First full moon of the month, often called the Flower Moon, occurs at 17:23 UTC (1:23 PM EDT). This is the Moon reaching full phase early in May, so the month starts with a full Moon.[1][2]
- May 31, 2026: The second full Moon of May (a “Blue Moon” by common naming conventions) turns full at 04:45 UTC (4:45 AM EDT). May 2026 is one of those months with two full Moons, giving observers two opportunities to see a bright Moon around month’s end.[2][3][5]
Additional context and viewing notes
- For best viewing, target the hours around local moonrise or moonset on those dates; the Moon’s brightness is most manageable around its quarter phases, but both full Moons are still striking on clear nights.[2]
- Some sources emphasize that the May 31 Moon is a “Blue Moon” in common usage (the second full Moon in a single calendar month), though this is not an astronomical blue Moon in a strict sense; it’s mostly about calendar timing.[4][5]
If you’d like, I can tailor viewing times for Fortaleza, Ceará (BR) and provide a simple sky-watcher checklist for those two May full Moons, plus any local weather considerations.
