The broader Perseid maximum extends beyond the two-hour nominal peak. Previous International Meteor Organization (IMO) observations place the traditional broad maximum in a range corresponding in 2026 to approximately 21:00 UTC on August 12 through 09:00 UTC on August 13.
NASA also places the peak from the evening of August 12 into the early hours of August 13. The New Moon on August 12 will leave the sky free of moonlight, allowing fainter meteors to remain visible where weather and local light pollution permit.
Watch live
The Virtual Telescope Project will broadcast the 2026 Perseid meteor shower live and free beginning at 22:30 UTC on August 12. The feed will use an all-sky camera at Manciano, Italy, in the Maremma countryside.
NASA’s Marshall Space Flight Center will hos their watch party live on YouTube, starting at 23:00 CT on August 12.
Throughout the broadcast, they will show real-time sky imagery from Marshall’s Automated Lunar and Meteor Observatory (ALaMO). Meteoroid experts from Marshall and guest subject matter experts will join the event to discuss the science behind the Perseids and answer your questions in real time.
IMO lists the Perseids as active from July 17 through August 24, with a nominal zenithal hourly rate (ZHR) of 100 and a meteoroid velocity of 59 km/s (37 miles/s). ZHR represents the calculated rate under ideal observing conditions with the radiant overhead and should not be read as a guarantee that an observer will see 100 meteors in one hour.
The Perseids originate from material released by comet 109P/Swift-Tuttle. Earth passes through the comet’s debris stream each year, and particles entering the atmosphere at high speed produce the streaks of light seen as meteors. The shower takes its name from its radiant near the constellation Perseus.
Viewing geometry favors mid-northern latitudes. IMO says the radiant reaches a reasonable elevation from approximately 22:00–23:00 LT onward at mid-northern sites. The shower cannot be properly viewed from most of the Southern Hemisphere or from latitudes north of approximately 60° N.
NASA advises observers to find a dark, open site, look generally toward the northeast after darkness falls and allow approximately 30 minutes for their eyes to adapt. Meteors can appear across any part of the sky, and viewing improves later in the night as the Perseid radiant rises higher.
Calculations cited by IMO place Earth at one branch of an old 1079 Swift-Tuttle dust trail at 16:53 UTC on August 12. Because the trail is very old, the calculation provides no estimate of resulting meteor activity.
A separate calculation places an encounter with a weak Swift-Tuttle filament near 01:00 UTC on August 13, with an uncertainty of ±5 hours. The modeled component has an expected ZHR of no more than 43. IMO notes that the trail and filament could become detectable if the normal Perseid background rate is lower.
Neither calculation establishes an outburst or meteor-storm forecast for 2026. IMO gives no activity estimate for the 1079 trail and describes the second component as a weak filament. Enhanced activity after the principal maximum has been recorded during some previous Perseid returns, and IMO recommends including the nights around the main maximum in observing programs.
The New Moon on August 12 leaves the 2026 maximum free of lunar interference. IMO describes the conditions as excellent for optical observations, leaving weather, sky darkness and local light pollution as the main constraints for observers.
