Can I see the stars tonight in Algiers?
Tonight's score for Algiers multiplies four things: how dark the sky gets, the NOAA GFS cloud forecast, the moon and the light pollution of the city. 100 is a moonless, cloudless night far from any town.
Tonight
Bad night: cloud, moonlight or light pollution hide all but the brightest stars and planets.

The sky over Algiers
Algiers sits under an estimated Bortle 9 sky (inner-city sky). Only the Moon, the planets and the very brightest stars get through the glow; the Milky Way is out of reach. From the centre the faintest stars visible to the naked eye are around magnitude 4.0.
Dark sky near Algiers: where to drive
The nearest sky of Bortle 4 or darker is about 58 km south of the centre (Bortle 4): there the lights of Algiers shrink to a dome on the horizon and the Milky Way shows its structure overhead. The darkest sky within 100 km is Bortle 4, about 88 km south of the centre.
37 At the darkest spot nearby (88 km south, Bortle 4) tonight: poor, best 20:00–23:00 UTC.
That is 34 points better than the city centre.
Once there, turn your back on Algiers: its light dome rises to the north, so the darkest part of the sky is the opposite way. Give your eyes 20–30 minutes away from screens and headlights and the faint stars come out.

When to look up from Algiers
From Algiers the bright core of the Milky Way, in Sagittarius and Scorpius, stands low in the south on summer evenings, from June to August. In autumn and winter the fainter outer arm runs overhead through Cassiopeia, Perseus and Gemini, beside Orion.
The best nights are the week either side of the new moon: a full moon high in the sky hides all but the brightest stars, while a crescent that sets early in the evening costs almost nothing.
The Bortle scale
| Class | Sky | Faintest star | What you see |
|---|---|---|---|
| Bortle 1 | excellent dark-sky site | 7.6–8.0 | The Milky Way is bright enough to cast faint shadows, the zodiacal light and airglow are visible, and thousands of stars reach down to the horizon. |
| Bortle 2 | truly dark sky | 7.1–7.5 | The Milky Way is full of detail, faint airglow may show near the horizon, and clouds look like black holes against the stars. |
| Bortle 3 | rural sky | 6.6–7.0 | The Milky Way is rich and textured overhead; distant towns are only a faint glow low on the horizon. |
| Bortle 4 | rural/suburban transition | 6.1–6.5 | The Milky Way is clearly visible overhead but loses detail towards the horizon, where the light domes of towns rise in several directions. |
| Bortle 5 | suburban sky | 5.6–6.0 | The Milky Way is weak and washed out, visible overhead only on the best nights; light domes cover much of the horizon. |
| Bortle 6 | bright suburban sky | 5.1–5.5 | The Milky Way is at most a faint trace straight up on the clearest nights; the sky is grey up to 35° above the horizon. |
| Bortle 7 | suburban/urban transition | 4.6–5.0 | The Milky Way is invisible; the whole sky has a grey-orange glow and only the main constellations stand out. |
| Bortle 8 | city sky | 4.1–4.5 | The sky glows orange or white: the Moon, the planets and a few dozen bright stars, enough to trace Orion or the Plough. |
| Bortle 9 | inner-city sky | 4.0 | Only the Moon, the planets and the very brightest stars get through the glow; the Milky Way is out of reach. |

How this forecast is made
The score is the LayEarth stars layer's: per hour, 100 × darkness (sun from 12° to 18° below the horizon) × clear sky (NOAA GFS low, middle and high cloud of the run of 2026-10-16 06:00 UTC, interpolated to the hour; high cloud counts 70%) × moon (its altitude and phase, computed) × light pollution (Bortle class estimated from NASA Black Marble 2016 night lights, summed within 100 km with Walker's law). It does not see haze, smoke, local horizons or lights brighter or dimmer since 2016: Bortle is an estimate from satellite data, not a meter reading. Cloud forecast reaches 48 hours; later nights are scored on darkness and moon alone. The live map grades every spot around Algiers.
