Astronomers say it could be possible to see one or two shooting stars every minute.
The spectacular display of celestial fireworks is promised as the Earth flies through a cloud of cometary dust.
The Perseid meteors, shed by comet Swift-Tuttle, stage their show every August and are among the brightest of all shooting stars.

This year, as many as two of the streaking flashes of light could be visible every minute given a good location away from built up areas and clear skies.
The peak time for Perseid watching will be tonight and before dawn tomorrow, but the meteors may already be making an appearance.
The meteors, mostly no bigger than a grain of sand, burn up as they hit the atmosphere at 58km per second to produce a shooting stream of light in the sky.
Seen from the Earth, the Perseids appear to originate from one place in the northeast known as the "radiant" which happens to be near the constellation Perseus.
The Perseids were the first meteor shower to be linked to a comet when astronomer Giovanni Schiaparelli spotted their association with Swift-Tuttle in 1862.
The comet orbits the Sun every 135 years.
As the Earth crosses its orbit, it ploughs through some of the debris left by the icy object on previous visits.
