Moon phase today: What the Moon will look like on September 13
See the Moon phase expected for September 13, 2026 as well as when the next Full Moon is expected.
On September 13, the Moon will be in its Waxing Crescent phase, according to NASA's Daily Moon Guide tracker. Only 5% of the lunar surface is visible from Earth during this phase. This marks the beginning of the lunar cycle, which spans approximately 29.5 days. As the Moon orbits Earth, its appearance changes due to its position relative to both Earth and the Sun, revealing varying portions of its sunlit side.
The Moon's phases progress from a thin crescent to a half-moon, then a full moon, before the cycle begins again. There are eight distinct phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter (or Last Quarter), and Waning Crescent.
