Meteor showers from Haikou in 2026

Meteor showers over Haikou in 2026

Twelve showers, one city. From Haikou, Hainan — 20.0°N, 110.35°E, 9 m, Asia/Shanghai — 12 of them put a radiant above the horizon in darkness at maximum, 6 pass ten an hour, and the Geminids tops the 2026 list at 146.3 an hour.

Clock time here runs 39 minutes ahead of mean solar time, so local solar midnight on the Geminids peak night falls at 00:33 rather than 00:00. Haikou, Hainan is the 117th largest of the 300 cities on this site, with a population of 2.87 million.

The three best nights of 2026 here

The Geminids peaks at 21:41 on 14 December 2026 Haikou time. Its radiant culminates 77.8° up at 02:41 bearing N, the Moon is 26% lit, and 23:00–06:00 is the window — about 146.3 meteors an hour on the reference sky.

Behind it, the Perseids manages 75.5 an hour on 13 August (radiant 49.0° at best, Moon 0% lit) and the Quadrantids 30.8 on 4 January (radiant 43.1°, Moon 100%). Those are the three nights worth defending in a calendar; the full ranking for Haikou is in the table below.

At the other end of the list the Ursids manages 2.8 an hour on 23 December with the radiant reaching 34.4° at culmination.

What this latitude allows

Every one of the twelve gets its radiant above the Haikou horizon at some point on the night of maximum — a property of the tropics at 20.0°N, where radiants in both celestial hemispheres rise at some hour. The lowest any of them culminates is the Ursids, at 34.4°.

Ursids (34.4° at culmination) never sets from 20.0°N at all — the radiant stays above the horizon around the clock, so darkness and the Moon are the only things limiting those nights.

Sunset, twilight and real darkness

On the Geminids peak night the Sun sets over Haikou at 18:01, astronomical darkness runs 19:19 to 05:47, and sunrise is 07:05 — 10 h 27 min of real darkness inside 13 h 5 min of night. These are Asia/Shanghai times, which is what you set an alarm by.

Across the twelve peak nights of 2026, astronomical darkness at Haikou runs from 8 h 18 min on the Southern delta-Aquariids night (31 July) to 10 h 28 min on the Ursids night (23 December). Long nights give a shower room to perform even when its radiant rises late.

Moon luck in 2026

Moon phase makes or breaks a meteor year. In 2026 the showers that catch a dark Moon from Haikou are Perseids (0% lit, 75.5/h).

Working against them, Quadrantids (100% lit), Orionids (78% lit), eta-Aquariids (79% lit) run into a bright Moon for most of the dark window, which is already priced into the rates quoted on this page.

Near Haikou

The closest other cities covered here are Yunfu (366 km NNE), Nanning (374 km NW), Haiphong (393 km WNW), Zhongshan (419 km NE), Guangzhou (456 km NE). Within a few tens of kilometres the radiant altitudes are effectively identical, so the reason to open a neighbour's page is the clock: sunset, moonrise and the peak window all shift with longitude and, across a border, with the time zone.

11 of the 300 cities lie within 500 km of here, and 92 share its country. The nearest, Yunfu, is 366 km NNE on a bearing of 28°.

What this page does not know

Light-pollution data for this location is not connected yet. Every rate here is computed against the reference rural sky the zenithal hourly rate is defined for (naked-eye limiting magnitude 6.5) and is not a statement about how bright this city's sky is. When the light-pollution layer lands these numbers will be recomputed and will generally fall.

Cloud cover is not baked into this page — it is a forecast that changes by the hour, so it is resolved live rather than at build time and shows as "unavailable" in the tables rather than being assumed to be zero. 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 figures quoted here. 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.
