Orionids from Hong Kong in 2026

Orionids from Hong Kong: the short answer

From Hong Kong (22.3°N, 60 m) the Orionids maximum of 02:23 on 22 October 2026 is not worth a broken night. The radiant culminates at 83.4° at 04:44, and against Hong Kong's own measured sky that converts to 3.2 meteors an hour at best.

That ranks it 5th of twelve from Hong Kong this year, behind the Geminids (21.7/h) and the Perseids (15.2/h).

The radiant track over this city

Orion carries the radiant. From Hong Kong it clears the horizon at 22:18 on a bearing of 73° (ENE), reaches 83.4° at 04:44 in the south, and drops back below the horizon at 11:10. Within the observing window it peaks at 82.4°.

When it gets dark here

Sunset over Hong Kong is 17:53, civil twilight ends 18:16, and the sky reaches astronomical darkness — Sun 18° down — at 19:08. It holds until 05:07, with sunrise at 06:22: 9 h 59 min of real darkness inside 12 h 29 min of night.

Local solar midnight, the true middle of the night, falls at 00:08 here rather than at 00:00: Asia/Hong_Kong runs 23 minutes ahead of mean solar time at 114.17°E. That offset is why the best hour on this page is not the hour you would guess from the clock.

What the Moon does here

Moonlight is the limiting factor on this night from Hong Kong. The Moon is 78% lit and only 3 of 11 sampled hours are moon-free. Moonrise 14:42. Moonset 02:24. At the best hour it stands 35.1° below the horizon, pulling the limiting magnitude down to 4.50.

Why 3 an hour and not 20

Zenithal hourly rate 20, population index 2.5, entry speed 66.1 km/s — very fast. Those are stream constants. What changes from city to city is the geometry: at 82.4° of radiant altitude and limiting magnitude 4.50, Hong Kong converts that ZHR into about 3.2 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 19:00 (radiant -39.7°) to 3.2 at 05:00 (radiant 82.4°), peaking at 3.2. That spread across 11 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 1P/Halley and is listed as active 2 October to 7 November, so 22 October 2026 is the best night from Hong Kong rather than the only one.

Watching from around Hong Kong

Hong Kong is the 37th largest of the 300 cities covered here, with a population of 7.40 million at 60 m above sea level. The nearest other cities on the site are Shenzhen (32 km NNW), Zhongshan (86 km WNW), Dongguan (93 km NNW) — close enough that the radiant altitudes barely change, far enough that sunset and moonrise do.

What this page does not know

Rates on this page are computed against this city's own measured sky brightness, derived from satellite night-lights data. That is a calculated brightness for the point directly overhead, not a survey of your street: a park on the edge of town and a lit car park in the centre share the same figure here and will not look the same. It is also zenith-only, while the Bortle scale describes the whole sky from horizon to horizon.

Cloud cover is a forecast, not a constant, so it is resolved when you load the tonight card and is deliberately absent from this prerendered page — the hourly table shows "unavailable" rather than assuming clear skies. Meteor outbursts, local terrain and building horizons are not modelled.

A single observer with an unobstructed horizon typically records 30–50% below the ideal-sky figure. Give your eyes twenty minutes to adapt, keep bright screens away, look about halfway up the sky rather than straight at the radiant, and count for a full hour before judging a shower.
