At 4:45 a.m. on May 31, 2026, a full moon will appear in the Montreal sky. Night owls will be able to watch it before going to bed (and sleeping until noon afterward), and early risers will be able to see it while enjoying their morning coffee.
It will be the second full moon of May 2026, and this phenomenon is called a “Blue Moon.”
The Blue Moon
The origins of the term “Blue Moon” are a bit unclear, because obviously the second full moon in May won’t actually appear blue. But that’s where the expression “once in a blue moon” (meaning “very rarely”) comes from.
It’s also a blue moon that Elvis sings about in “Blue Moon.”
The term is used to refer to a month with two full moons—since the lunar cycle lasts only 29.5 days, this is possible from time to time.
It’s still a rare event with an aura of mysticism, and we recommend doing something mysterious and exceptional this Sunday, May 31, 2026. A poem, a declaration of love, an unexpected stroll, a cosmic revelation.
and the Flower Moon of May
The first full moon of May 2026 will be high in the Montreal sky on May 1, and it is the Flower Moon.
The full moon in May is called the Flower Moon in North America because this is the time of year when the trees are in bloom.
In May, in Montreal, we’ll be able to see;
- Japanese cherry trees(Prunus serrulata)
- the Magnolias(Magnolia Grandiflora)
- the serviceberry(Amelanchier canadensis)
- Apple Trees(Malus baccata)
The name “Flower Moon” was given to the May moon by the Algonquin people—as confirmed by Christina Ruddy of The Algonquin Way Cultural Centre in Pikwakanagan, Ontario.
