Perseids from Melbourne in 2026

Perseids from Melbourne: the short answer

Melbourne, Victoria sits at 37.8°S, 144.96°E, and the Perseids radiant never rises here. Maximum falls at 12:00 local time on 13 August 2026, but the radiant's best altitude over the whole 24 hours is -5.9° — still below the horizon. At declination +57.9° it would need a latitude south of about -32° to clear it, and this city is 5.9° short.

The radiant track over this city

Over the full 24 hours of 13 August 2026 the radiant — declination +57.9°, right ascension 47.8°, inside the boundaries of Cassiopeia — swings between -5.9° and well below that, never touching the Melbourne horizon. The shower is a northern-hemisphere event and this is a southern-hemisphere city 37.8° from the equator.

When it gets dark here

The dark hours here run 19:11 to 05:37 — 10 h 26 min of astronomical night, bracketed by sunset at 17:42 and sunrise at 07:06. Civil twilight ends at 18:09; anything earlier than that is wasted effort.

Local solar midnight, the true middle of the night, falls at 00:24 here rather than at 00:00: Australia/Melbourne runs 20 minutes ahead of mean solar time at 144.96°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 1% illuminated and below the horizon for 12 of the 12 sampled dark hours, so moonlight subtracts essentially nothing here. Moonrise 07:51. Moonset 18:18. At the best hour the limiting magnitude reaches 5.26 — the reference sky's full value.

Why 0 an hour and not 100

The published ZHR of 100 assumes the radiant overhead and a sky at limiting magnitude 6.5. Here the radiant reaches -6.0° inside the dark window and the limiting magnitude at the best hour is 5.26, which with r = 2.2 gives 0.0 an hour. Entry speed is 58.8 km/s.

Hour by hour the modelled rate runs from 0.0 at 19:00 (radiant -68.0°) to 0.0 at 06:00 (radiant -6.0°), peaking at 0.0. 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 Melbourne rather than the only one.

Watching from around Melbourne

Melbourne, Victoria is the 50th largest of the 300 cities covered here, with a population of 5.44 million at 25 m above sea level. The nearest other cities on the site are Adelaide (654 km WNW), Sydney (713 km NE), Brisbane (1375 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.
