Perseid meteor shower begins: Best times and tips for viewing
The Perseid meteor shower, described as one of the most impressive celestial events of the year, has begun. Earth has started passing through a trail of dust and debris left behind by the comet Swift-Tuttle, creating the annual phenomenon that will remain active through late August. While the shower is already underway, experts note that activity will gradually ramp up over the coming weeks. The display is expected to reach its peak during the overnight hours of Aug. 12 into Aug. 13.
Understanding the Perseids
The Perseids are caused by Earth passing through debris shed by comet Swift-Tuttle, an icy object discovered in 1862. Scientists believe the comet is more than 4 billion years old and note that its nucleus is approximately 16 miles wide, making it the largest object known to repeatedly pass Earth. As these particles—often roughly the size of a grain of sand—slam into the Earth’s atmosphere, they vaporize, creating bright streaks of light. These meteors can travel at speeds of up to 37 miles per second, or roughly 130,000 mph. The shower is particularly famous for producing vivid, colorful meteors and “fireballs,” which are especially bright displays that can briefly light up the night sky.
When and Where to Watch
While individual meteors may be spotted as early as 10 p.m., the best viewing opportunities occur during the late-night and pre-dawn hours. According to the American Meteor Society, the hours just before sunrise are often the most active, as the radiant—the point in the sky where the meteors appear to originate—rises higher in the sky. For the 2026 event, the moon phase is expected to be favorable. A new moon falls on Aug. 12, just before the peak, which will provide darker sky conditions compared to previous years when moonlight drowned out dimmer shooting stars. Although the meteors appear to radiate from the constellation Perseus, experts advise that they can streak across any part of the sky. Viewers should look toward the north, or the northeast in southern latitudes, to catch the trails at their longest.
Optimizing the Viewing Experience
Visibility is heavily impacted by light pollution. Scientists emphasize that heading to dark, remote locations away from city lights is the most effective way to improve the quality of the display. For those in suburban areas where total darkness is difficult to find, experts recommend the following: * Patience: Allow your eyes to adjust to the darkness for at least 20 to 30 minutes before expecting to see the most meteors. * Equipment: No telescopes or binoculars are required. The event is best viewed with the naked eye to capture the widest possible field of vision. * Environment: Find a clear, open space where you can comfortably look up at the sky. In Southern California, locations such as Joshua Tree National Park and Anza-Borrego Desert State Park are cited as ideal spots for viewing due to their distance from the light pollution of metropolitan areas like Los Angeles.
What to Expect at the Peak
During the peak on the night of Aug. 12 and into the morning of Aug. 13, observers under perfectly dark skies could potentially see dozens to over 100 meteors per hour. NASA notes that while numbers vary, 50 to 100 meteors per hour can be observed during much of the shower’s duration. Because the meteors are the result of Earth passing through the densest section of the comet’s debris stream during this mid-August window, the frequency of shooting stars drops off significantly in the days following the peak. However, even outside the peak window, the Perseids remain one of the most reliable and spectacular astronomical events of the summer season.
