Here’s what you asked about: a blue moon occurring on May 31, 2026.
Direct answer
- May 31, 2026 features a Blue Moon, which is the second full Moon in May 2026. It won’t look distinctly blue, but it earns the “blue moon” label because it’s the extra full Moon in the same calendar month. The peak illumination is around the early morning hours of May 31 in many time zones.
Key details and context
- What makes it special: It’s the second full Moon in May, a calendar-based anomaly that happens only occasionally, earning the common name “Blue Moon.” It may also be referred to as a micromoon in some reports because the Moon’s apparent size is slightly smaller than average at this time, depending on viewer location and orbital geometry.

Viewing tips
- Best viewing windows: In general, the period from just after sunset on May 30th through post-midnight May 31st gives the clearest opportunity, weather permitting. Peak illumination times are reported around the early hours of May 31 in several regions, with exact local times varying by your time zone. For observers in Europe, North America, and parts of Asia, check local moonrise/moonset times and weather forecasts as the date approaches. [Common guidance from skywatching outlets]
What to watch for in public coverage
- Reports emphasize that this Blue Moon coincides with being one of the year’s smallest Full Moons (a micromoon) due to it’s near apogee, which can affect apparent size and brightness in some conditions. Expect widespread coverage noting the rarity of two full Moons in May and the early-morning peak timing. [Several science/astronomy outlets]
