Perseids from Ahmedabad in 2026

Perseids from Ahmedabad: the short answer

Maximum for the Perseids in 2026 is 07:30 Ahmedabad time on 13 August 2026. From 23.0°N the radiant gets to 55.1° at 06:26, the Moon is 0% lit, and this city's measured-sky ceiling is 15.0 meteors an hour.

That ranks it 2nd of twelve from Ahmedabad this year, behind the Geminids (21.9/h).

The radiant track over this city

Cassiopeia carries the radiant. From Ahmedabad it clears the horizon at 21:35 on a bearing of 23° (NNE), reaches 55.1° at 06:26 in the north, and drops back below the horizon at 15:15. Within the observing window it peaks at 51.8°.

When it gets dark here

Sunset over Ahmedabad is 19:14, civil twilight ends 19:37, and the sky reaches astronomical darkness — Sun 18° down — at 20:34. It holds until 04:55, with sunrise at 06:15: 8 h 21 min of real darkness inside 11 h 1 min of night.

Local solar midnight, the true middle of the night, falls at 00:44 here rather than at 00:00: Asia/Kolkata runs 40 minutes ahead of mean solar time at 72.59°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 0% illuminated and below the horizon for 10 of the 10 sampled dark hours, so moonlight subtracts essentially nothing here. Moonrise 06:38. Moonset 19:05. At the best hour the limiting magnitude reaches 4.50 — the full value for this city's measured sky.

Why 15 an hour and not 100

Zenithal hourly rate 100, population index 2.2, entry speed 58.8 km/s — fast. Those are stream constants. What changes from city to city is the geometry: at 51.8° of radiant altitude and limiting magnitude 4.50, Ahmedabad converts that ZHR into about 15.0 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 20:00 (radiant -6.7°) to 12.2 at 05:00 (radiant 51.8°), peaking at 15.0. That spread across 10 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 109P/Swift-Tuttle and is listed as active 17 July to 24 August, so 13 August 2026 is the best night from Ahmedabad rather than the only one.

Watching from around Ahmedabad

Ahmedabad, Gujarat is the 46th largest of the 300 cities covered here, with a population of 6.36 million at 56 m above sea level. The nearest other cities on the site are Vadodara (103 km SE), Surat (205 km S), Indore (334 km E) — close enough that the radiant altitudes barely change, far enough that sunset and moonrise do.

What this page does not know

Rates on this page are computed against this city's own measured sky brightness, derived from satellite night-lights data. That is a calculated brightness for the point directly overhead, not a survey of your street: a park on the edge of town and a lit car park in the centre share the same figure here and will not look the same. It is also zenith-only, while the Bortle scale describes the whole sky from horizon to horizon.

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.
