Observadores in different parts of the globe will have the opportunity to appreciate the natural satellite in its fullness. The celestial body will appear bright and completely round in the night sky on both Thursday, April 30th and Friday, May 1st.

Maio of 2026 stands out for presenting an unusual astronomical event: the occurrence of two full moons within the same month. Esta condition, which occurs on average every 18 months, according to information from EarthSky, gives a particularity to the lunar calendar. The first is the aforementioned Lua of Flor, while the second fullness, on May 31, will be categorized as an Lua Azul, a term used to designate the second full moon in a single month.

Detalhes of the first full moon of May

The Lua of Flor reaches its peak illumination in the early afternoon, but its nighttime visibility will not be compromised. The spectacle can be observed with the naked eye, without the need for specialized equipment. Para enthusiasts, the location of the star in the sky in Escorpião adds extra detail to the experience.

The satellite began the night of Thursday, April 30, in a gibbous crescent phase, displaying about 98% of its total illumination, according to data from Time and Date. Essa proximity to fullness already offers an impactful look even before the exact moment of its greatest luminosity. The transition to 100% lighting occurs gradually.

The name “Moon of Flor” for the full moon of May dates back to ancient traditions. The name reflects the explosion of flowers that occurs across vast regions of América’s Norte during this time of year, as documented by Old Farmer’s Almanac. Essa connection to seasonal nature enriches the symbolism of the event, linking the lunar cycle to the rebirth of plant life.

Calendário full lunar May 2026

The month of May 2026 will be especially active for skywatchers, with several lunar phases marking the period. Acompanhar the complete calendar allows a more in-depth understanding of the cycles of our natural satellite. Estas are the main dates:

  • Lua Cheia: May 1st
  • Último Quarto: May 9
  • Lua Nova: May 16
  • Primeiro Quarto: May 23
  • Lua Cheia: May 31st
