Stargazing in Las Vegas
How dark Las Vegas's sky really is, which way to head to escape it, and a live seven-night forecast — scored honestly from cloud, moon and light pollution.
What you can actually see from Las Vegas
The sky over the city centre sits at about Bortle 9(16.57 mag/arcsec², 2024 atlas) — an approximation from modelled zenith brightness, not a field measurement (what each level means).
From the middle of Las Vegas the sky glows too brightly for the Milky Way to show at all. What the city does give you is the Moon, the bright planets — Jupiter, Saturn, Venus, Mars — and the few brightest stars and star clusters, which cut through light pollution regardless. Everything fainter — the Milky Way, galaxies, most nebulae, a rich meteor shower — needs you to leave the glow behind.
Which way to escape the glow
The fastest way out of Las Vegas's light dome is to head east. In that direction the atlas shows the sky darkening to around Bortle 4 — dark enough for the Milky Way — within roughly 40 km of the centre. That's also the way toward Grand Canyon-Parashant National Monument, the nearest certified dark-sky place (145.9 km out).
Directions and distances are sampled from the light-pollution atlas as the crow flies — real roads, terrain and a clear horizon still matter, so treat this as where to point the car, not a turn-by-turn route.

The Orionid meteor shower from Las Vegas: 21–22 October 2026
The Orionids — fast meteors from Comet 1P/Halley, up to ~20 an hour under ideal dark skies (IMO) — peak overnight on 21–22 October 2026. From Las Vegas, the radiant in northern Orion climbs to about 70° above the southern horizon before dawn. Because 2026's peak lands under a bright ~80% waxing gibbous Moon, evening watching will disappoint — the productive window is the pre-dawn hours as the Moon sinks and sets.
Stacking Las Vegas's Bortle 9 inner-city glow on top of an ~80% Moon leaves only the occasional bright fireball from town. If the pre-dawn forecast is clear, use the escape route above for the dark window after moonset.
Because 21–22 October is within the 16-night forecast window, you can check Las Vegas's exact peak-night cloud cover and local moonset time on the Orionids 2026 live viewing forecast.
The Geminid meteor shower from Las Vegas: 13–14 December 2026
The Geminids — the year's richest shower, up to ~150 meteors an hour under ideal skies — peak on the night of 13–14 December 2026. The Moon cooperates this year: a ~21% crescent sets during the evening, leaving the main hours dark. That leaves the two local factors this page is about: cloud on the night, and how far you get from the city's glow.
From the Bortle 9 city centre only the brightest fireballs cut through the glow — the faint majority of Geminids needs darker sky. The escape routes and certified sites above are exactly what the peak night is for.
For scored peak-night conditions — cloud through the dark hours at your exact spot — open the Geminids 2026 live viewing forecast once 13 December comes within the 16-night horizon.
Plan the next 90 days from Las Vegas
Moon-free dark windows are astronomy — computable years ahead. Cloud is not: beyond the 16-night forecast nobody knows the weather, and we won't pretend to. What five years of observations can say is how often each month's nights actually stayed clear here. Both are below — read them for what they are.
- Oct 4–1613 moon-free nights92% of October nights here stayed clear (2021–2025)
- Nov 2–1514 moon-free nights89% of November nights here stayed clear (2021–2025)
- Dec 2–1413 moon-free nights80% of December nights here stayed clear (2021–2025)
- Dec 31 – Jan 1314 moon-free nights80% of December nights here stayed clear (2021–2025)
Clearest months in Las Vegas historically: June (97%), September (96%), April (94%).
