Peak: August 12, 1933, around 06:00 UTC — up to about 100 meteors an hour under a dark sky. The Moon will be 59% lit: some moonlight, which will hide the fainter meteors. Meteors seem to come from Perseus; the debris is from Comet Swift–Tuttle. The Northern Hemisphere's favorite: warm nights and bright, fast meteors.
