The annual Perseid meteor showers, which seem to radiate from the constellation Perseus, have been viewable to some extent since around July 17. But tonight, they are expected to be at their peak, with as many as 80 meteors streaking the sky hourly.
You can look up for them throughout the night tonight, but especially promising times are between 9 and 11 p.m. PDT, and before dawn on Wednesday morning, according to a NASA blog (by the way, this NASA post provides a fun 101 on meteors).

Just before the first rays of Wednesday, you may see “dozens” of the shooting stars. The 9-to-11 p.m. window, though, is when you should watch for what astronomers call “earthgrazers,” which may make up for their lack of frequency with their memorable good looks. These are “meteors that approach from the horizon and skim the atmosphere overhead like a stone skipping across the surface of a pond,” said Bill Cooke of NASA, as quoted in another NASA post. “They are long, slow and colorful — among the most beautiful of meteors.”
Be warned that the Perseids’ visibility may be mildly obscured by an especially bright moon tonight, according to a Discover Magazine blog. Yet, it should still be a great show.
