Peaks 08/12 at up to 100 per hour under ideal conditions. Active, peaking in 5 days.
Status right now: Active, peaking in 5 days.
The best-known shower of the year: warm nights, a high radiant, and plenty of bright meteors.
The Perseids come from comet 109P/Swift-Tuttle, and enter the atmosphere at about 59 kilometres per second. That is fast, which tends to produce brief, sharp streaks that often leave persistent trains.
The quoted rate of 100 per hour is the zenithal hourly rate — the count you would get with the radiant directly overhead, under a perfectly dark sky, with no moon. Nobody's actual conditions match that. Real counts are typically a third to a half of the headline figure, and considerably less with a bright moon or from a town.
SkyRef scales the estimate by the real altitude of the radiant from your location and tells you when the moon is going to ruin it, rather than repeating a number you will never see.
Do not use a telescope or binoculars — meteors appear all over the sky and you want the widest possible view. Lie back, look roughly halfway up, and give your eyes twenty minutes to adapt. Face away from the moon if it is up. Patience matters more than equipment.
