The American Meteor Society also notes that the moon may give viewers some difficulty. Perseids' peak occurs just three days after August's full moon, so the moon will still be mostly full. Thus, it is highly probable that light pollution from the moon may reduce the number of visible meteors by a hefty margin, depending on how things go.

The Perseids run through August 23, but the peak is coming up on the nights of August 12–13 when Earth hits the dustiest part of the comet’s trail, per Weather. The moon will be almost full this year (about 84%), which could wash out a lot of the fainter meteors. The American Meteor Society says we could miss up to 75% of the action.
