Orionid Meteor shower Peaks Tonight, October 21-22, 2025: What Time to Watch
the Orionid Meteor Shower is expected to peak tonight, October 21st, and into the early hours of October 22nd, 2025. While pinpointing an exact time is difficult due to the gradual nature of meteor shower peaks,several sources offer guidance for optimal viewing.
According to one source, the theoretical peak time for meteors is 00.00 WIB (Western Indonesian Time). However, the best viewing opportunity arises after the radiant point – the area of the sky from which the meteors appear to originate – is high in the eastern sky. This is estimated to occur around 01.00 WIB on October 22nd.
The American Meteor Society corroborates the peak timeframe,stating it will occur on the evening of October 21-22,2025,though without specifying a precise time. The Journal & Courrier suggests the period between midnight on October 21st and 2 am on October 22nd as a potentially favorable window.
Experts note that meteor shower peaks are gradual events, unlike the precise predictability of lunar eclipses.
What to Expect: Zenithal Hourly Rate (ZHR)
The number of meteors visible will depend on the Zenithal Hourly Rate (ZHR), which represents the number of meteors potentially visible in one hour under ideal conditions. The International meteor Organization (IMO) 2025 Meteor Shower Calendar indicates an average ZHR of 20-30 for the Orionids, based on observations from 2012-2020. Historically, between 2006-2009, the ZHR was higher, ranging from 40-70. This year, the peak ZHR is estimated to be above 20, considered a moderate but observable rate.
How to View the Shower:
* Find a secluded, dark viewing location.
* Allow your eyes to adjust to the darkness for 15-20 minutes.
* Wear comfortable clothing appropriate for the weather.
* Bring a blanket if you plan to observe for an extended period.
* Lie down and look up at the sky.
* Focus your gaze towards the radiant point above the eastern horizon.
Optimal Viewing Conditions:
Fortunately, the Moon will not interfere with viewing this year. The Moon will be between the Earth and the Sun,resulting in minimal illumination on the side facing Earth. Dark skies are crucial for visibility, and no special equipment like telescopes or binoculars are necessary – the naked eye is sufficient once adapted to the darkness.
The Orionid Meteor Shower is visible from both the northern and southern hemispheres. Observers should look towards the constellation Orion to maximize their chances of spotting the meteors.
