Southern delta-Aquariids from Dar es Salaam in 2026

Southern delta-Aquariids from Dar es Salaam: the short answer

Marginal from Dar es Salaam. Maximum 16:23 on 31 July 2026; the radiant reaches 80.9° at 02:30 and the ideal-sky rate tops out at 3.8 an hour with the Moon 95% lit.

That ranks it 10th of twelve from Dar es Salaam this year, behind the Geminids (115.7/h) and the Perseids (40.1/h).

The radiant track over this city

The radiant rises at 20:23 bearing ESE, culminates 80.9° up at 02:30 towards south (180°), and sets at 08:38. It lies inside Aquarius. The rate scales with the sine of that altitude, so 80.9° buys you 99% of a zenith radiant.

When it gets dark here

Dar es Salaam loses the Sun at 18:23 and gets it back at 06:34. True astronomical darkness — the only part that counts for faint meteors — runs 19:36 to 05:22, 9 h 46 min out of 12 h 11 min of night.

Local solar midnight, the true middle of the night, falls at 00:29 here rather than at 00:00: Africa/Dar_es_Salaam runs 23 minutes ahead of mean solar time at 39.27°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

Moonlight is the limiting factor on this night from Dar es Salaam. The Moon is 95% lit and only 2 of 12 sampled hours are moon-free. Moonrise 19:58. Moonset 08:27. At the best hour it stands 49.4° above the horizon, 8° from the radiant, pulling the limiting magnitude down to 5.07.

Why 4 an hour and not 25

Converting ZHR 25 into something useful for Dar es Salaam means multiplying by sin(78.5°) and dividing by 3.2 raised to (6.5 − 5.07). That lands at 3.8 meteors an hour, from fast 40.6 km/s entries.

Hour by hour the modelled rate runs from 0.0 at 19:00 (radiant -19.7°) to 0.0 at 06:00 (radiant 38.1°), peaking at 3.8. That spread across 12 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 96P/Machholz and is listed as active 12 July to 23 August, so 31 July 2026 is the best night from Dar es Salaam rather than the only one.

Watching from around Dar es Salaam

Dar es Salaam is the 51st largest of the 300 cities covered here, with a population of 5.38 million at 24 m above sea level. The nearest other cities on the site are Nairobi (673 km NNW), Kakamega (936 km NNW), Kampala (1087 km NW) — 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.
