The fireball phenomenon is at its most intense when Earth crosses the path of comet Swift-Tuttle at surprising speeds.
In the UK, the meteor shower is expected to peak between the nights of August 11 and August 12.
Amateur astrologers can expect to see as many as 80 meteors hurtling across the night sky – weather permitting.

St Lawrence’s day falls on August 10 and this is why Catholics associate the shooting stars with fiery tears.
Patron saint of cooks, St Lawrence was tortured and martyred by the Romans in 258 AD during the persecution of the emperor Valerian along with many other members of the Roman clergy.
During his torture, St Lawrence was said to have been burned on a grill, and despite the extreme pain he was enduring, he supposedly quipped: “Turn me over – I am done on this side!”
As he was executed on August 10, many Catholics associate the Perseid meteor shower with St Lawrence and dub the shooting stars as the “tears of St Lawrence” as they occur at the same time each year.
Astronomy website Slooh said: “In medieval Europe, the Perseids were called the ‘Tears of St Lawrence’.
“This is because they occur near the anniversary of the death of Laurentius, a Christian deacon who was martyred by the Roman Emperor Valerian in the year 258 AD.”
