The Orionids in 2026: Halley's Comet meteors, and how to beat an 80% Moon
Every October Earth ploughs through debris left by Comet 1P/Halley, producing fast, train-leaving meteors visible from both hemispheres. In 2026 the peak night — 21-22 October — lands under a bright ~80% waxing gibbous Moon. We won't hype a compromised night: evening watching will disappoint, and the only productive window is the pre-dawn hours as the Moon sinks and sets.

Will you see the Orionids?
Enter where you'll be watching from. Once the night of 21-22 October 2026 enters the 16-night horizon, Stellarhound scores its cloud and moon conditions, then shows your local light-pollution ceiling separately. Before then, it says what is knowable now instead of inventing a forecast. No signup; your location is used for this lookup only and never stored.
The honest 2026 picture: why pre-dawn is the only window that counts
In a dark year the Orionids deliver a respectable ZHR of around 20 meteors per hour under ideal skies (International Meteor Organization). In 2026, the Moon is about 80% illuminated on the peak night. Moonlight acts like artificial light pollution: it raises the background brightness of the sky and erases the fainter meteors that make up the bulk of any shower.
What saves the night from being a write-off is geometry. A waxing gibbous Moon rises in the afternoon and sets in the pre-dawn hours — just as the constellation Orion climbs to its highest point before morning twilight. Enter your city in the forecast box above to see the exact local moonset time and dark-sky window for 21-22 October, along with the live cloud-cover score.
What makes Orionid meteors worth catching
The Orionids are one of two annual showers born from Comet 1P/Halley (the other is May's Eta Aquariids). Because Earth meets the stream nearly head-on after midnight, Orionid meteoroids hit the upper atmosphere fast — producing swift streaks and persistent ionized trains that hang in the sky for a second or two after the meteor itself has gone.
The shower also has a broad peak plateau. Activity runs from 2 October to 7 November (IMO), and several mornings around 20-24 October often produce comparable rates. If the night of 21-22 October is clouded out at your location, check the 16-night forecast for the clearest pre-dawn morning on either side.
Where to look — in either hemisphere
The radiant sits in northern Orion, just north of the bright orange supergiant Betelgeuse, at about +16° declination. Unlike far-northern showers that leave southern observers out, Orion rises high enough for viewers across both the Northern and Southern Hemispheres.
Don't stare straight at Orion — meteors near the radiant have foreshortened, stubby trails. Look about two-thirds of the way up the sky, 40-60° away from the radiant (Andromeda, Taurus or Gemini in the north; Eridanus or Canis Major in the south), and keep the Moon behind a building, tree line or hill while it is still above the horizon.
How to watch under a bright Moon
- Time it to moonset. Skip the evening hours. Set an alarm for the last couple of hours before dawn when Orion is high and the waxing gibbous Moon is low in the west or already down.
- Block the Moon directly. If you go out before moonset, position yourself in the moon-shadow of a house, wall or ridge so the lunar glare never hits your eyes directly.
- No optics. Telescopes and binoculars restrict your field of view to a fraction of a degree; meteors are a naked-eye, whole-sky event.
- Protect your night vision. Give your eyes 20 minutes to adapt and use Stellarhound's red-light mode (top right) if you check your phone.
- Or save your drive for December. If you only make one dark-sky trip this season, the Geminids on 13-14 December 2026 bring up to ~150 ZHR under a dark sky after an early-setting crescent Moon.
Orionids 2026: quick answers
When do the Orionids peak in 2026?
The Orionids peak overnight on 21–22 October 2026, within a broad activity window that runs from 2 October to 7 November (International Meteor Organization). Because the peak is relatively flat, several pre-dawn mornings around 20–24 October offer similar rates.
What time of night is best to watch the 2026 Orionids?
The pre-dawn hours — roughly between 2 a.m. and dawn local time. That is when the radiant in Orion climbs highest in the sky and the bright waxing gibbous Moon (~80% lit) sinks low or sets. Going out before midnight in 2026 means fighting a high, bright Moon while the radiant is still low.
Will moonlight ruin the Orionids in 2026?
It will wash out most faint meteors during the evening and midnight hours — the Moon is about 80% illuminated on the peak night (IMO). Your best strategy is to check your exact local moonset time in the forecast box above and watch in the dark window between moonset and morning twilight.
How many Orionid meteors will I actually see?
The quoted ZHR is around 20 per hour (International Meteor Organization), which assumes a perfectly dark sky and the radiant directly overhead. Under 2026's ~80% Moon and typical suburban light pollution, expect a handful of bright meteors per hour — rising if you catch a clear pre-dawn hour after the Moon sets from a dark site.
Can you see the Orionids from both hemispheres?
Yes. The radiant sits near +16° declination in northern Orion, high enough to rise well above the horizon across both the Northern and Southern Hemispheres.
What comet causes the Orionid meteor shower?
Comet 1P/Halley. Earth crosses Halley's debris stream twice a year — producing the Eta Aquariids in May and the Orionids in October. Orionid meteors strike the atmosphere fast and often leave glowing ionized trains that linger for a second or two.
When is the next dark-moon major meteor shower in 2026?
The Geminids on the night of 13–14 December 2026 — the year's richest shower (ZHR up to ~150 under ideal skies), peaking with a thin ~21% crescent Moon that sets during the evening and leaves the main hours completely dark.
