Geminids from Cairo in 2026

Worth planning for

Geminids: about as good as this shower gets

Plan for 22:00–06:00 local time: the radiant reaches 88° above the horizon, the Moon is 28% lit, and astronomical darkness lasts 10 h 56 min. Under the reference dark sky that rates about 150 meteors an hour — cloud cover is a runtime fact this page cannot know, so treat it as the ceiling, not a promise.

Geminids from Cairo: the short answer

The Geminids reaches maximum at 15:41 local time on 14 December 2026 over Cairo (30.1°N, 31.25°E, 23 m). The radiant culminates 87.9° high at 01:58 and the useful window runs 22:00–06:00, with an ideal-sky ceiling of 149.9 meteors an hour.

That makes the Geminids the strongest of the twelve annual showers from Cairo in 2026, ahead of the Perseids at 77.4 an hour.

The radiant track over this city

Gemini carries the radiant. From Cairo it clears the horizon at 18:32 on a bearing of 52° (NE), reaches 87.9° at 01:58 in the north, and drops back below the horizon at 09:23. Within the observing window it peaks at 87.9°.

When it gets dark here

Sunset over Cairo is 16:56, civil twilight ends 17:22, and the sky reaches astronomical darkness — Sun 18° down — at 18:21. It holds until 05:17, with sunrise at 06:43: 10 h 56 min of real darkness inside 13 h 47 min of night.

Local solar midnight, the true middle of the night, falls at 23:49 here rather than at 00:00: Africa/Cairo runs 5 minutes behind mean solar time at 31.25°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 28% lit and out of the way for 9 of the 13 sampled dark hours. Moonrise 10:57. Moonset 21:41. At the best hour it is 53.5° below the horizon, and the limiting magnitude works out at 6.50.

Why 150 an hour and not 150

Zenithal hourly rate 150, population index 2.6, entry speed 33.8 km/s — medium-speed. Those are stream constants. What changes from city to city is the geometry: at 87.9° of radiant altitude and limiting magnitude 6.50, Cairo converts that ZHR into about 149.9 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 18:00 (radiant -5.4°) to 1.1 at 06:00 (radiant 39.0°), peaking at 149.9. That spread across 13 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Minor planet (3200) Phaethon and is listed as active 4 December to 20 December, so 14 December 2026 is the best night from Cairo rather than the only one.

Watching from around Cairo

Cairo is the 23rd largest of the 300 cities covered here, with a population of 9.61 million at 23 m above sea level. The nearest other cities on the site are Alexandria (180 km NW), Beirut (585 km NE), Damascus (611 km NE) — 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.

"Cloud: n/a" means the forecast is not resolved on this prerendered page, not that the sky is clear.
