The Perseid meteor shower will reach its maximum rate of activity on 13 August 2016. 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 11 days old at the time of peak activity, and being so close to Full Moon, will severely limit the observations that will be possible.

The radiant of the Perseid meteor shower is at around right ascension 02h20m, declination +58°, as shown by the green cross on the planetarium above. At midnight, it appears 48° above the north-eastern horizon from London. All of the meteors will appear to be travelling directly outward from this point, as indicated by the white lines drawn above.

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 30-40° away from it, since it is at a that distance from the radiant that meteors will typically appear at their brightest.
