Meteor showers from Coimbatore in 2026

Meteor showers over Coimbatore in 2026

Latitude 11.0°N, longitude 76.97°E, elevation 411 m, time zone Asia/Kolkata: those four numbers decide most of what Coimbatore, Tamil Nadu can see. 12 of the twelve annual showers get their radiant up in darkness at maximum here and 3 are worth a late night, led by the Geminids at 53.5 meteors an hour.

Clock time here runs 22 minutes ahead of mean solar time, so local solar midnight on the Geminids peak night falls at 00:16 rather than 00:00. Coimbatore, Tamil Nadu is the 173rd largest of the 300 cities on this site, with a population of 2.14 million.

The three best nights of 2026 here

The Geminids peaks at 19:11 on 14 December 2026 Coimbatore time. Its radiant culminates 68.8° up at 02:25 bearing N, the Moon is 27% lit, and 23:00–06:00 is the window — about 53.5 meteors an hour on this city's own measured sky.

Behind it, the Perseids manages 27.4 an hour on 13 August (radiant 41.2° at best, Moon 0% lit) and the Quadrantids 12.0 on 4 January (radiant 38.2°, Moon 100%). Those are the three nights worth defending in a calendar; the full ranking for Coimbatore is in the table below.

At the other end of the list the Ursids manages 0.9 an hour on 23 December with the radiant reaching 25.4° at culmination, and the faintest one that still puts anything measurable in the sky here is the Southern delta-Aquariids at 1.0 an hour on 31 July.

What this latitude allows

Every one of the twelve gets its radiant above the Coimbatore horizon at some point on the night of maximum — a property of the tropics at 11.0°N, where radiants in both celestial hemispheres rise at some hour. The lowest any of them culminates is the Ursids, at 25.4°.

Nothing is circumpolar from 11.0°N among these twelve: every radiant sets at some point, which is why the hourly tables on the shower pages for Coimbatore rise and fall rather than staying flat.

Sunset, twilight and real darkness

On the Geminids peak night the Sun sets over Coimbatore at 18:01, astronomical darkness runs 19:16 to 05:16, and sunrise is 06:32 — 10 hours of real darkness inside 12 h 31 min of night. These are Asia/Kolkata times, which is what you set an alarm by.

Across the twelve peak nights of 2026, astronomical darkness at Coimbatore runs from 8 h 54 min on the Southern delta-Aquariids night (31 July) to 10 hours 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 Coimbatore are Perseids (0% lit, 27.4/h).

Working against them, Quadrantids (100% lit), Orionids (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 Coimbatore

The closest other cities covered here are Madurai (175 km SE), Bengaluru (229 km NNE), Kallakurichi (232 km ENE), Tirunelveli (265 km SSE), Chennai (428 km ENE). 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.

5 of the 300 cities lie within 500 km of here, and 24 share its country. The nearest, Madurai, is 175 km SE on a bearing of 134°.

What this page does not know

Every rate here uses this city's measured sky brightness, derived from satellite night-lights data and modelled down to a zenith brightness. It is one number for a whole metropolitan area, so a dark park on the edge of town will beat it and a floodlit street will not match it, and it describes the sky overhead rather than the whole horizon-to-horizon view the Bortle scale grades.

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.
