The Perseids meteor shower, often called one of the most spectacular sky events of the year, will peak on August 12–13, 2025. For viewers in North America, the prime time will be early Wednesday morning, according to the American Meteor Society (AMS).
However, this year’s peak coincides with a waning gibbous moon that will be 84% full, which could significantly reduce visibility.
Moonlight’s Impact on the Perseids
AMS experts warn that the bright moonlight will likely reduce meteor activity by at least 75%, making only the brightest fireballs visible. Under ideal dark-sky conditions, the Perseids can produce up to 50 meteors per hour. This year, expect only 10–20 meteors per hour.
Robert Lunsford from AMS explains, “If a bright moon is above the horizon during the night of maximum activity, the display will be reduced as most Perseid meteors are faint and will be washed out by moonlight.”
When and Where to Watch
The Perseids are active from mid-July to August 23, 2025. NASA and astronomy experts suggest that early morning before sunrise is the best time to watch, though meteors can sometimes be seen as early as 10 p.m.
For better viewing despite the moonlight, Thaddeus LaCoursiere of the Bell Museum in Minnesota recommends heading out a week after the peak when the moon is less bright. Rural, dark-sky areas will offer the best chances to spot meteors.
Origin of the Perseids
The Perseids appear to radiate from the constellation Perseus, which gives them their name. However, they are actually caused by space debris from comet 109P/Swift-Tuttle, which last passed through the inner solar system in 1992. As Earth moves through this debris field, particles burn up in the atmosphere, creating bright streaks across the sky.
During the peak, Earth will pass closest to the comet’s core orbit, increasing meteor activity — although moonlight will dim the overall display this year.
Viewing Tips from Experts
- Choose a dark rural location away from city lights.
- Let your eyes adjust to the dark for at least 20–30 minutes.
- Avoid using phone screens or bright lights while watching.
- Lie down comfortably and look up at the sky for the widest view.
- Watch between midnight and dawn for the best chance of spotting meteors.
