Meteor showers from Curitiba in 2026

Meteor showers over Curitiba in 2026

Latitude 25.4°S, longitude 49.27°W, elevation 924 m, time zone America/Sao_Paulo: those four numbers decide most of what Curitiba, Paraná can see. 11 of the twelve annual showers get their radiant up in darkness at maximum here and 2 are worth a late night, led by the Geminids at 79.6 meteors an hour.

Clock time here runs 17 minutes ahead of mean solar time, so local solar midnight on the Geminids peak night falls at 00:11 rather than 00:00. Curitiba, Paraná is the 196th largest of the 300 cities on this site, with a population of 1.95 million.

The three best nights of 2026 here

The Geminids peaks at 10:41 on 14 December 2026 Curitiba time. Its radiant culminates 32.3° up at 02:20 bearing N, the Moon is 22% lit, and 00:00–04:00 is the window — about 79.6 meteors an hour on the reference sky.

Behind it, the Orionids manages 14.8 an hour on 21 October (radiant 48.6° at best, Moon 82% lit) and the Perseids 9.5 on 12 August (radiant 6.5°, Moon 0%). Those are the three nights worth defending in a calendar; the full ranking for Curitiba is in the table below.

At the other end of the list the Ursids manages 0.0 an hour on 22 December with the radiant reaching -10.9° at culmination, and the faintest one that still puts anything measurable in the sky here is the Northern Taurids at 3.3 an hour on 12 November.

What this latitude allows

Latitude decides what is available at all. From 25.4°S, Ursids never lift a radiant above the Curitiba horizon at maximum — the best any of them manages over the whole 24 hours is -10.9°, still under the horizon. Their radiants sit too far into the northern sky, and only travelling fixes that.

Nothing is circumpolar from 25.4°S among these twelve: every radiant sets at some point, which is why the hourly tables on the shower pages for Curitiba rise and fall rather than staying flat.

Sunset, twilight and real darkness

On the Geminids peak night the Sun sets over Curitiba at 19:02, astronomical darkness runs 20:32 to 03:50, and sunrise is 05:20 — 7 h 19 min of real darkness inside 10 h 18 min of night. These are America/Sao_Paulo times, which is what you set an alarm by.

Across the twelve peak nights of 2026, astronomical darkness at Curitiba runs from 7 h 17 min on the Ursids night (22 December) to 10 h 26 min on the Southern delta-Aquariids night (31 July). 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 Curitiba are Perseids (0% lit, 9.5/h).

Working against them, Orionids (82% lit), eta-Aquariids (83% lit) run into a bright Moon for most of the dark window, which is already priced into the rates quoted on this page.

Near Curitiba

The closest other cities covered here are São Paulo (339 km NE), Porto Alegre (547 km SSW), Rio de Janeiro (678 km ENE), Belo Horizonte (821 km NE), Asunción (841 km W). 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.

1 of the 300 cities lie within 500 km of here, and 12 share its country. The nearest, São Paulo, is 339 km NE on a bearing of 52°.

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.
