How long does the moon stay full? Buck Moon still appears full tonight

The July Buck Moon—set to reach full phase on Wednesday, July 29—will likely appear full for the next two nights, including Thursday, July 30 and Friday, July 31. While a moon is only “truly full” at a precise instant, it can look full to the naked eye for two to three nights, with the July 29 moon remaining nearly full after the peak. The next full moon, the Sturgeon Moon, peaks Friday, Aug. 28 at 12:18 a.m. ET. The Perseid meteor shower remains active from July 17 through Aug. 24, peaking Aug. 12 or 13.
