Viewing the Perseid Meteor Shower in 2026

The Perseids are active from July 17 through August 24 each year. These meteors are visible to anyone viewing between the latitudes of 60° N and 40° S. Locations north of 60° N experience twilight during the critical observing hours, and the sky never becomes completely dark at this time of year. The Perseid radiant never rises south of 40° S, so all Perseid activity is blocked from view at these southern latitudes. For those able to view the Perseids, activity near the beginning and the end of the activity period is less than one shower member per hour and is produced by highly perturbed meteoroids from comet 109P/Swift-Tuttle. As we approach the August 13 maximum, activity will increase with each passing night. The bright Moon in late July greatly reduced the number of faint Perseids that could be seen. The Moon reaches its last quarter phase on August 5, marking the beginning of the best observing window for the 2026 Perseids. At this time though the half-illuminated moon will be located in the nearby constellation of Aries, so potential Perseid observers will be forced to look well away from the radiant in Perseus in order to avoid having the moonlight ruin their night vision. This condition will persist through August 8, when the moon’s eastern motion carries it through the nearby constellation of Taurus. By August 9 the slender crescent moon will enter the constellation of Gemini and will finally be far enough from the radiant to cease being a nuisance. On the morning of August 9, hourly rates during the final dark hour before dawn should approach 10 as seen from dark sky sites. During the following three mornings, rates should increase to approximately 15, 20, and 30 meteors per hour. Hourly rates during the same time period for the next three nights should be near 15, 20, and 30. On the evening of August 12, hourly rates should be 5, increasing to 10 by midnight. During the early morning hours, rates should increase rapidly to nearly 40 per hour by 3:00 a.m. local daylight time. In theory, rates should continue to increase until the beginning of astronomical twilight, During my many years of observing this shower, however, I have usually noticed a slight decline during the final dark hour before dawn. This apparent decline may simply be the result of observer fatigue and should be compared with simultaneous video observations. A peak rate of 40 Perseids per hour is considerably lower than many published predictions for this year’s shower. I may be mistaken, but recent Perseid returns have been weaker than average, and meteor shower expert Mikhail Maslov expects this trend to continue through 2026, with enhanced activity beginning in 2027.*

While we hope that observers will monitor the Perseid activity on multiple nights, most will concentrate on the night of maximum activity August 12/13. The following observing suggestions are applicable for a week on either side of the maximum as seen from mid-northern latitudes. Try to view from the darkest site possible. Many local astronomical clubs have safe dark sky sites that may be open to the public during the Perseid shower. Perseid meteors can be seen at all hours of the night. If you are limited to viewing during the evening hours, look toward the north with your view halfway up in the sky. You will see Perseid meteors shooting upward from the northeastern horizon. At this time of night they tend to be long and long-lasting.  Many of these will also be seen low in the eastern and western sky, moving nearly parallel to the horizon. Perseid rates will be low, but there should be other slower random meteors visible at this time of night. By midnight, the radiant will lie one-third high in the sky and Perseid meteors will be seen shooting in all directions. By 4:00 a.m., the Perseid radiant stands about two-thirds of the way up the sky, and approximately 90 percent of all Perseid meteors are visible. One hundred percent of the shower activity is never visible because the radiant reaches its highest point during daylight. This is why zenith hourly rates are always higher than what is actually seen unless you are viewing under superbly dark skies with a limiting magnitude exceeding +7.0.

No matter when you are viewing, you should place the Perseid radiant at the edge of your field of view so that you can easily tell if the meteor is shooting from Perseus or is a random meteor. This is most important on nights away from maximum when Perseid activity is lower. On the night of maximum more than ninety percent of all meteors will be Perseids. Not all Perseid meteors look alike. Most will be dim and barely perceptible. Meteors seen close to the radiant will appear to move more slowly than those further out. They also will be shorter as seen in the featured photograph. If photographing this display, you will want to center your camera at least 45 degrees from the radiant. You will also want to center your camera so that the bottom of your field of view is just above the horizon. This is because many more meteors become visible through the thicker layer of atmosphere near the horizon. This is especially true for fireballs, which often appear during the Perseid display.

When viewing meteor activity, there are always peaks and lulls of activity. One may go ten minutes without seeing any activity and then see three within the next minute. Therefore we suggest that observers watch for a minimum of one hour so that neither a brief lull nor a short burst of activity dominates the observing session. This is another reason why we suggest recording the time of each meteor so that the particle density can be measured and compared to other observers who are watching at the same time.

People are often surprised to learn that meteor observing has substantial scientific value, especially when observations are systematic and shared. In fact, much of what we know about meteor showers, meteoroid streams, and even near-Earth debris comes from coordinated visual, video, radar, and photographic observations by both professionals and amateur astronomers. Visual observers help determine the strength, timing, and activity profiles of meteor showers. Visual meteor observations can also provide information about the physical properties of meteors by recording properties such as magnitude (brightness), color, and the presence of persistent trains. Experienced observers either write this data in the field or dictate them into a recorder so their eyes remain on the sky. Regardless of how you collect data, it is important to share your data with those who analyze such reports. The easiest way to do this is to fill out a visual meteor report form at the website of the International Meteor Organization. You will need to register, but there is no cost to share your data. This is also a great way to archive your data and to refer to past observations. Your data also contributes to the Visual Meteor Database which astronomers use to study long-term changes in meteor activity.

We hope you will take advantage of the moon-free skies and observe the Perseids this year. Please consider recording and submitting your observations so we can determine whether the recent period of reduced Perseid activity continues or whether the shower has begun the stronger phase predicted for the next several years.
