when will i see the blue moon tonight

The moon phase tonight, August 28, 2025, is a Waxing Crescent. This means it is not a full moon night, so there will not be a "blue moon" visible tonight. A blue moon, by the astronomical definition, refers to either the second full moon in a calendar month or the third full moon in a season of four full moons. The next blue moon is not tonight but will occur on May 31, 2026. Therefore, tonight, the moon will appear as a waxing crescent with about 25% illumination, not as a blue moon. The next full moon, which could be relevant for blue moon observation, is on September 7, 2025, but that is not tonight either.
