Orionids from Abidjan in 2026

Orionids from Abidjan: the short answer

From Abidjan (5.4°N, 50 m) the Orionids maximum of 18:23 on 21 October 2026 is not worth a broken night. The radiant culminates at 79.7° at 04:36, and against Abidjan's own measured sky that converts to 3.1 meteors an hour at best.

That ranks it 5th of twelve from Abidjan this year, behind the Geminids (19.7/h) and the Perseids (12.1/h).

The radiant track over this city

At 5.4°N a declination-+15.7° radiant traces an arc from 22:31 to 10:42, topping out at 79.7° at 04:36 bearing 0°. Inside the dark window it only manages 78.2°, and that lower figure is the one the rates are built from. The radiant currently lies in Orion.

When it gets dark here

Sunset over Abidjan is 17:59, civil twilight ends 18:20, and the sky reaches astronomical darkness — Sun 18° down — at 19:09. It holds until 04:51, with sunrise at 06:01: 9 h 41 min of real darkness inside 12 h 1 min of night.

Local solar midnight — the true middle of the night — lands within a minute of 00:00 here, because Africa/Abidjan happens to sit almost exactly over 4.00°W once the equation of time is taken out. Most cities are not that lucky; the clock and the sky usually disagree by tens of minutes.

What the Moon does here

Moonlight is the limiting factor on this night from Abidjan. The Moon is 81% lit and only 3 of 11 sampled hours are moon-free. Moonrise 14:32. Moonset 02:45. At the best hour it stands 18.5° below the horizon, pulling the limiting magnitude down to 4.50.

Why 3 an hour and not 20

Zenithal hourly rate 20, population index 2.5, entry speed 66.1 km/s — very fast. Those are stream constants. What changes from city to city is the geometry: at 78.2° of radiant altitude and limiting magnitude 4.50, Abidjan converts that ZHR into about 3.1 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 19:00 (radiant -48.9°) to 1.5 at 05:00 (radiant 78.2°), peaking at 3.1. That spread across 11 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 1P/Halley and is listed as active 2 October to 7 November, so 21 October 2026 is the best night from Abidjan rather than the only one.

Watching from around Abidjan

Abidjan is the 47th largest of the 300 cities covered here, with a population of 6.32 million at 50 m above sea level. The nearest other cities on the site are Kumasi (302 km ENE), Accra (422 km E), Lomé (584 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.
