The Perseid meteor peaks tonight (evening of the 12th, morning of the 13th of August). This year is favourable, like 2005 there is no Moon to wash out the sky.
Observers will need to look in an easterly direction, the radiant is within the constellation of Perseus. However it's best to view as much of the sky as possible rather than focus on the small area around Perseus.
If you stay out for an hour or two you should see perhaps a dozen or two meteors under good conditions.
Some tips for beginners; take a deck chair out there so you can lie down and look at the sky, get away from as many lights as possible to avoid destroying any dark adaptation. You may also want to bring some drink and or food if you get hungry, and bring something to keep you warm as under clear skies it can get quite chilly.
