Moon enters waxing crescent phase on September 19, 2026

On Saturday, September 19, 2026, the Moon enters its waxing crescent phase. During this stage, approximately 60% of the lunar surface is visible, appearing in the western sky shortly after sunset.

This phase is noted by astronomers for being an ideal time for observation. The presence of the “terminator”—the line dividing the illuminated side from the dark side—creates shadows that highlight lunar craters and mountains with high clarity.

The lunar cycle, or lunation, lasts an average of 29.5 days, transitioning through new, waxing crescent, full, and waning phases. Following the waxing crescent, the next full moon is expected on September 26, 2026.

Beyond visual interest, the Moon's gravitational pull significantly influences Earth's tides. Experts note that the interaction between lunar phases and rising sea levels caused by climate change can increase the frequency and intensity of coastal flooding and erosion.
