Perseids from Lima in 2026

Perseids from Lima: the short answer

Maximum for the Perseids in 2026 is 21:00 Lima time on 12 August 2026. From 12.0°S the radiant gets to 19.9° at 05:55, the Moon is 0% lit, and the ideal-sky ceiling is 32.5 meteors an hour.

That ranks it 2nd of twelve from Lima this year, behind the Geminids (107.1/h).

The radiant track over this city

At 12.0°S a declination-+57.9° radiant traces an arc from 01:15 to 10:35, topping out at 19.9° at 05:55 bearing 0°. Inside the dark window it only manages 19.9°, and that lower figure is the one the rates are built from. The radiant currently lies in Cassiopeia.

When it gets dark here

Sunset over Lima is 18:03, civil twilight ends 18:25, and the sky reaches astronomical darkness — Sun 18° down — at 19:15. It holds until 05:10, with sunrise at 06:22: 9 h 54 min of real darkness inside 12 h 19 min of night.

Local solar midnight, the true middle of the night, falls at 00:12 here rather than at 00:00: America/Lima runs 8 minutes ahead of mean solar time at 77.03°W. 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 12 of the 12 sampled dark hours, so moonlight subtracts essentially nothing here. Moonrise 07:02. Moonset 18:13. At the best hour the limiting magnitude reaches 6.50 — the reference sky's full value.

Why 33 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 19.9° of radiant altitude and limiting magnitude 6.50, Lima converts that ZHR into about 32.5 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 19:00 (radiant -42.4°) to 0.2 at 06:00 (radiant 19.9°), peaking at 32.5. That spread across 12 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 12 August 2026 is the best night from Lima rather than the only one.

Watching from around Lima

Lima is the 34th largest of the 300 cities covered here, with a population of 7.74 million at 152 m above sea level. The nearest other cities on the site are La Paz (1077 km ESE), Guayaquil (1139 km NNW), Quito (1324 km N) — 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.
