what moon phase is tonight

The moon phase tonight, August 17, 2025, is a Waning Crescent. The moon is about 35% illuminated and the visible portion is decreasing as it moves toward the New Moon phase. This phase is best viewed just before sunrise in the western sky. So if you look up tonight, you'll see the crescent shape of the moon with more than half in shadow. This Waning Crescent phase means the lunar cycle is nearing its end before starting anew with the New Moon in about 6 days.
