Quadrantids from Sydney in 2026

Quadrantids from Sydney: the short answer

The Quadrantids reaches maximum at 08:12 local time on 4 January 2026 over Sydney, New South Wales (33.9°S, 151.21°E, 58 m). The radiant culminates 6.5° high at 09:20, with an ideal-sky ceiling of 0.0 meteors an hour.

That ranks it 11th of twelve from Sydney this year, behind the Geminids (60.8/h) and the Orionids (12.1/h).

The radiant track over this city

At 33.9°S a declination-+49.8° radiant traces an arc from 06:49 to 11:51, topping out at 6.5° at 09:20 bearing 360°. Inside the dark window it only manages -11.5°, and that lower figure is the one the rates are built from. The radiant currently lies in Bootes.

When it gets dark here

Sunset over Sydney is 20:09, civil twilight ends 20:38, and the sky reaches astronomical darkness — Sun 18° down — at 21:52. It holds until 04:06, with sunrise at 05:49: 6 h 14 min of real darkness inside 9 h 40 min of night.

Local solar midnight, the true middle of the night, falls at 00:59 here rather than at 00:00: Australia/Sydney runs 55 minutes ahead of mean solar time at 151.21°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 Sydney. The Moon is 100% lit and only 0 of 9 sampled hours are moon-free. Moonrise 20:21. Moonset 06:06. At the best hour it stands 5.4° above the horizon, 88° from the radiant, pulling the limiting magnitude down to 1.93.

Why 0 an hour and not 110

Zenithal hourly rate 110, population index 2.1, entry speed 40.4 km/s — fast. Those are stream constants. What changes from city to city is the geometry: at -11.5° of radiant altitude and limiting magnitude 1.93, Sydney converts that ZHR into about 0.0 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 21:00 (radiant -73.5°) to 0.0 at 05:00 (radiant -11.5°), peaking at 0.0. That spread across 9 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Minor planet 2003 EH1 and Comet C/1490 Y1 and is listed as active 28 December to 12 January, so 4 January 2026 is the best night from Sydney rather than the only one.

Watching from around Sydney

Sydney, New South Wales is the 48th largest of the 300 cities covered here, with a population of 5.64 million at 58 m above sea level. The nearest other cities on the site are Melbourne (713 km SW), Brisbane (733 km NNE), Adelaide (1162 km W) — close enough that the radiant altitudes barely change, far enough that sunset and moonrise do.

What this page does not know

Light-pollution data for this location is not connected yet. Rates on this page are computed against the reference rural sky the zenithal hourly rate is defined for (naked-eye limiting magnitude 6.5); they are not a claim about how bright the sky is where you are standing. Once the light-pollution layer is connected these figures will be recomputed for the local sky and will generally fall.

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.
