Air Quality in North Las Vegas, Nevada — Live

Live readings from PurpleAir sensors across North Las Vegas — with free alerts when summer ozone or windblown dust turns the air unhealthy.

Live North Las Vegas AQI from nearby PurpleAir sensors loads when this page opens in a browser, along with a live sensor map covering North Las Vegas and Las Vegas, Henderson, Sunrise Manor, Aliante.

North Las Vegas sits inside the Las Vegas Valley, a desert basin in the Mojave ringed by the Spring Mountains to the west and Sunrise Mountain to the east, and for most of the year the air here is genuinely unremarkable — dry, sunny, and low in particle pollution. The two real problems are tied to the calendar. Summer heat and traffic combine to form ozone faster than the valley's light winds can clear it, which is part of why federal regulators reclassified the area to serious nonattainment for ozone in January 2025. Then, from roughly mid-June through late September, monsoon thunderstorms can trigger haboobs — walls of wind-blown desert dust that can send the AQI from clear to hazardous in minutes.

Canairy watches the sensors around your home, your kids' school, and everywhere else you care about, and tells you in plain English when the air changes enough to matter.

Why North Las Vegas's ozone problem keeps getting worse

The Las Vegas Valley is a roughly 600-square-mile basin, and the mountains that ring it — the Spring Mountains to the west, Sunrise Mountain to the east — do more than frame the scenery. They also block the kind of steady wind that would flush pollution out, so on hot, still summer days exhaust from the valley's freeways and surface streets cooks into ozone instead of blowing through. There's no heavy manufacturing base here to blame; Clark County's own air quality planning points to motor vehicle emissions as the dominant contributor.

That's shown up in the federal paperwork. The EPA first classified the Las Vegas Valley as marginal nonattainment for the 2015 ozone standard in June 2018. After the area missed that deadline, it was bumped to moderate nonattainment in January 2023, and after missing the moderate deadline too, it was reclassified again to serious nonattainment effective January 21, 2025, with a new attainment deadline of August 2027. Each step up means tighter rules for the county — and a clear signal that hot-weather ozone, not wildfire smoke, is the valley's main air quality fight.

Summer monsoons bring haboobs, not wildfire smoke

Unlike a lot of Western cities, North Las Vegas's worst air days rarely trace back to a fire burning nearby. Clark County's dust season runs from about mid-June through late September, when monsoon thunderstorms send outflow winds racing ahead of the storm and pick up loose desert soil across the valley floor. These haboobs have knocked out power lines, grounded flights, and dropped visibility to near zero on the valley's worst days, with local news outlets tracking them as a recurring summer hazard rather than a once-a-decade event.

The dust problem isn't only about summer storms, though. The valley's fine alluvial-fan soil turns to airborne PM10 easily whenever it's disturbed, which is why the region spent years working to fix a 1987-era federal nonattainment designation for particulate matter. The EPA didn't determine the valley had reached attainment until August 2010, and didn't approve Clark County's full redesignation and maintenance plan until October 2014, effective that November. The county filed a second PM10 maintenance plan in 2025 to keep proving the fix — built largely on dust-control permits that require builders to water and cover exposed dirt — is holding.

One valley number hides a lot of local variation

North Las Vegas covers more than 100 square miles, from the master-planned neighborhoods of Aliante and Craig Ranch in the north to the older, industrial blocks around Nellis Air Force Base in the southeast, plus the Apex industrial area near the city's northern edge, home to the country's largest landfill by area. Wind direction on any given day decides whether dust from Apex, ozone drifting up from the valley's freeway corridors, or neither actually reaches a particular neighborhood.

That's why Canairy reads the network of PurpleAir sensors scattered across North Las Vegas instead of relying on one valley-wide monitor. Set a threshold for your home or your kid's school, and you'll hear about it the moment the air there — not just the official valley average — crosses it.

North Las Vegas air quality FAQ

What is the air quality in North Las Vegas right now?

This page shows the current AQI for North Las Vegas, calculated from PurpleAir sensors across the city and updated continuously. The map below shows every live sensor, so you can check the reading closest to your own neighborhood, from Aliante to the Apex industrial area.

Why does North Las Vegas get dusty in the summer?

From about mid-June through late September, monsoon thunderstorms can trigger haboobs — walls of wind-blown desert dust pushed ahead of the storm's outflow winds. The Las Vegas Valley's fine alluvial soil lifts easily once disturbed, which is also why the region spent decades working to fix a 1987 federal nonattainment designation for dust (PM10) before finally reaching a durable maintenance status in 2014.

Is North Las Vegas's ozone problem getting worse?

It's trending the wrong way on paper: the EPA classified the Las Vegas Valley as marginal nonattainment for ozone in 2018, moved it to moderate in 2023, and reclassified it again to serious nonattainment effective January 2025, with a new deadline of August 2027. The driver is summer heat combining with vehicle emissions in a basin that traps the air rather than heavy industry.

What AQI level is unhealthy?

Under the US EPA scale, AQI 0-50 is Good and 51-100 is Moderate. From 101 the air is Unhealthy for Sensitive Groups - kids, older adults, and people with asthma or heart conditions - and above 150 it's Unhealthy for everyone. Canairy translates these numbers into a plain-English verdict, like whether to close the windows or move a workout indoors.

Where does Canairy's North Las Vegas data come from?

Readings come from PurpleAir's network of laser particle sensors across North Las Vegas and surrounding towns, cross-referenced with government monitors and the Google Air Quality API. You can see every sensor behind your numbers on the live map - there's no black box.
