This lunation took place on May 31, 2026 and has passed. The next is the Total Solar Eclipse in Leo on August 12, 2026. The ritual framing below still reads well as reflection on what that moon opened.
What is the Blue Moon (Strawberry Moon)?
May 31, 2026 brings a Blue Moon, the second full moon in a single calendar month. Falling at 10° Sagittarius, this rare lunation is the year's bonus expansion window. The chart suggests Sagittarius's adventurous wisdom-seeking energy makes this Blue Moon particularly favorable for bold vision-setting and travel intentions.
A Blue Moon is the second full moon in a single calendar month, an astronomical rarity that occurs roughly every 2-3 years. The phrase 'once in a blue moon' references exactly this uncommon event. May 31, 2026's Blue Moon falls in Sagittarius, making it the year's bonus expansion lunation, the second chance May offers to work with full moon energy.
For the evergreen reading of any moon in this sign, beyond just 2026, see the Full Moon in Sagittarius guide, which covers what Sagittarius brings to every lunation, not just this one.

Energetic Theme
Sagittarius is the mutable fire sign whose traditional Western astrological domain is wisdom-seeking, exploration, philosophy, distant journeys (literal and metaphorical), and the pursuit of meaning. The full moon in Sagittarius activates these themes at maximum intensity, while the opposing Gemini sun asks about the relationship between local quick exchange and far horizon vision.
In Yasmin Boland's Moonology framework, the Sagittarius full moon is described as 'the far-horizon lunation', the moment when the larger vision of your life asks for acknowledgment. The Blue Moon status amplifies this energy, many people find that Blue Moons produce particularly clear vision about long-arc direction.
Selene's Ritual for the Blue Moon (Strawberry Moon)
On the evening of May 31, take time to consider the larger arc of your life. The Sagittarius Blue Moon asks: what far horizon is calling you that local concerns have been obscuring? Write without editing until the far horizon has a shape you could describe to someone else.
Next, identify one specific commitment that honors the far horizon you've named. Sagittarius rewards bold vision but also asks for practical anchoring, what one move can you make in the next month that signals you've heard the larger call?
Finally, the Blue Moon is traditionally a window for travel ritual, whether literal travel planning or symbolic journey work. Selene's traditional practice is to spend time outdoors after dark, eyes on the actual moon, and let the body recognize that something rare is happening.
Reflection Prompts
Selene's traditional practice is to spend time with these prompts during the lunation's 48-hour energetic window. Write rather than think them through, Boland's Moonology work consistently finds that written reflection produces clarity that mental rumination does not.
- 1.What far horizon is calling me that local concerns have been obscuring?
- 2.What larger vision of my life is asking for acknowledgment?
- 3.What journey (literal or metaphorical) wants commitment?
- 4.What wisdom-seeking has been deferred that this Blue Moon makes available?
- 5.Where is my Gemini quick-exchange energy obscuring my Sagittarian far vision?

No, the phrase is historical naming convention rather than visual description. The moon will appear its usual brightness on May 31, 2026. Some atmospheric conditions (volcanic ash, fires) can occasionally make the moon appear blue or red, but the Blue Moon name itself refers to the second-in-a-month timing, not color.
