The Perseids are visible from all over the Northern Hemisphere. To have the best chance of seeing a meteor, pick a dark area (as far from bright city lights as possible) and face northeast. The meteors were appear to radiate out from the constellation Perseus, hence their name: Perseids.
While showers are hard to forecast, astronomers with the Royal Astronomical Society believe there will be at least one meteor every few minutes. A NASA advisory for the 2015 Perseid meteor shower predicted up to 100 meteors per hour.
