Geminids from Hefei in 2026

Geminids from Hefei: the short answer

The Geminids reaches maximum at 21:41 local time on 14 December 2026 over Hefei, Anhui (31.9°N, 117.28°E, 24 m). The radiant culminates 89.7° high at 02:14 and the useful window runs 22:00–06:00, with an ideal-sky ceiling of 149.8 meteors an hour.

That makes the Geminids the strongest of the twelve annual showers from Hefei in 2026, ahead of the Perseids at 84.0 an hour.

The radiant track over this city

Gemini carries the radiant. From Hefei it clears the horizon at 18:41 on a bearing of 51° (NE), reaches 89.7° at 02:14 in the north, and drops back below the horizon at 09:46. Within the observing window it peaks at 87.0°.

When it gets dark here

Sunset over Hefei is 17:08, civil twilight ends 17:34, and the sky reaches astronomical darkness — Sun 18° down — at 18:35. It holds until 05:36, with sunrise at 07:03: 11 h 1 min of real darkness inside 13 h 55 min of night.

Local solar midnight, the true middle of the night, falls at 00:05 here rather than at 00:00: Asia/Shanghai runs 11 minutes ahead of mean solar time at 117.28°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

The Moon is 26% lit and out of the way for 9 of the 13 sampled dark hours. Moonrise 11:08. Moonset 21:41. At the best hour it is 52.5° below the horizon, and the limiting magnitude works out at 6.50.

Why 150 an hour and not 150

Zenithal hourly rate 150, population index 2.6, entry speed 33.8 km/s — medium-speed. Those are stream constants. What changes from city to city is the geometry: at 87.0° of radiant altitude and limiting magnitude 6.50, Hefei converts that ZHR into about 149.8 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 18:00 (radiant -6.6°) to 8.4 at 06:00 (radiant 42.7°), peaking at 149.8. That spread across 13 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Minor planet (3200) Phaethon and is listed as active 4 December to 20 December, so 14 December 2026 is the best night from Hefei rather than the only one.

Watching from around Hefei

Hefei, Anhui is the 56th largest of the 300 cities covered here, with a population of 5.05 million at 24 m above sea level. The nearest other cities on the site are Lu’an (74 km W), Huainan (89 km NNW), Wuhu (123 km ESE) — 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.
