Perseids from Dar es Salaam in 2026

Perseids from Dar es Salaam: the short answer

For Dar es Salaam, Perseids maximum lands at 05:00 on 13 August 2026. Culmination 06:09 at 25.2° — that is 43% of what the same stream would deliver with the radiant overhead — and the ceiling on the rate is 12.3 meteors an hour.

That ranks it 2nd of twelve from Dar es Salaam this year, behind the Geminids (27.6/h).

The radiant track over this city

The radiant rises at 00:53 bearing NNE, culminates 25.2° up at 06:09 towards north (0°), and sets at 11:26. It lies inside Cassiopeia. The rate scales with the sine of that altitude, so 25.2° buys you 43% of a zenith radiant.

When it gets dark here

Dar es Salaam loses the Sun at 18:24 and gets it back at 06:31. True astronomical darkness — the only part that counts for faint meteors — runs 19:35 to 05:20, 9 h 45 min out of 12 h 7 min of night.

Local solar midnight, the true middle of the night, falls at 00:27 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

The Moon is 0% illuminated and below the horizon for 12 of the 12 sampled dark hours, so moonlight subtracts essentially nothing here. Moonrise 06:57. Moonset 18:15. At the best hour the limiting magnitude reaches 5.00 — the full value for this city's measured sky.

Why 12 an hour and not 100

Converting ZHR 100 into something useful for Dar es Salaam means multiplying by sin(25.2°) and dividing by 2.2 raised to (6.5 − 5.00). That lands at 12.3 meteors an hour, from fast 58.8 km/s entries.

Hour by hour the modelled rate runs from 0.0 at 19:00 (radiant -38.0°) to 0.6 at 06:00 (radiant 25.2°), peaking at 12.3. 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 13 August 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

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.
