The forecast for the peak of the 2013 Perseid meteor shower was this morning (August 12, 2013) but a very comparable amount of meteors will be visible at dawn on Tuesday, August 13.
So far this year there have been reports of several dozen meteors per hour and isolated reports of 50-60 meteors per hour. This is very comparable to the average rate of The Perseids meteor shower which is one meteor per minute.
The best place to view the meteor shower will be away from city lights. This particular meteor shower takes place across the entire night sky so no need to look towards a specific area. The best viewing window is from about 2 a.m. until dawn tomorrow morning. Also in the sky tonight, the waxing crescent moon will be visible with the planet Saturn in the southwestern sky at dusk.
