The Perseid meteor shower will reach its maximum rate of activity on 13 August 2015. Some shooting stars associated with the shower are expected to be visible each night from 23 Jul to 20 Aug.

The maximum rate of meteors expected to be visible from a dark location is around 80 per hour (ZHR). The Moon will be 28 days old at the time of peak activity, and so will present minimal interference.

The radiant of the Perseid meteor shower is at around right ascension 02h20m, declination +58°. At midnight, it appears 48° above your north-eastern horizon from London (click to change). All of the meteors will appear to be travelling directly outward from this point.

The best place to look to see as many meteors as possible is not at the radiant itself, but at any dark patch of sky which is around 90° away from it, since it is at a distance of around 90° from the radiant that meteors will typically appear at their brightest.
