Air Quality in Newport News, Virginia — Live

Newport News sits at the mouth of the James River, and for most of the year its air is unremarkable in the best way — this isn't a wildfire-smoke city like the ones out West. The story here is heat: on hot, still, humid summer afternoons, tailpipe and industrial exhaust from the Hampton Roads shipping and highway corridors cooks into ground-level ozone, and that's when the numbers move.
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.
Newport News once had a real ozone problem — and fixed it
The EPA's Green Book lists Newport News as a marginal nonattainment area for both the 1979 one-hour and 1997 eight-hour ozone standards, part of the wider Norfolk-Virginia Beach-Newport News (Hampton Roads) nonattainment area. Neighboring Hampton, York County, Virginia Beach, and Chesapeake were all redesignated to maintenance status back on July 28, 1997 — Newport News took a decade longer, only clearing the bar on June 1, 2007.
That decade-long gap says something about what was driving the numbers here specifically: the city carries more of the region's heavy industry and through-traffic than its neighbors. Newport News Shipbuilding, now part of Huntington Ingalls Industries, is Virginia's largest industrial employer with more than 26,000 workers building and overhauling nuclear aircraft carriers on the waterfront, and Interstate 64 and Interstate 664 both funnel Peninsula commuter and freight traffic past the same stretch of the James River.
Why summer is the season to watch
Newport News has a humid subtropical climate — hot, sticky summers and mild winters — with the James River and Hampton Roads harbor on three sides of the city keeping humidity high even when there's no rain in the forecast. That combination of heat, moisture, and light wind is exactly what turns vehicle and industrial exhaust into ground-level ozone instead of just letting it disperse.
At just 15 feet of elevation and surrounded by water, the peninsula doesn't get the kind of cleansing wind that scours pollution out of a valley. Still, muggy afternoons can let ozone build through the day before an evening sea breeze off the Bay finally clears it out — that's the pattern worth watching through the warm months, not a single smoky week.
The one time smoke did show up: June 2023
Newport News isn't a wildfire-smoke city the way California or the Pacific Northwest are, but it wasn't entirely spared during the extraordinary 2023 Canadian wildfire season. On June 2, 2023, smoke from wildfires burning in Nova Scotia pushed south and affected air quality across Virginia, Maryland, Pennsylvania, and Washington, D.C. — the same event that turned skies orange in New York and Philadelphia a few days later.
It was a genuine exception, not a preview of a new normal — Newport News doesn't sit downwind of a regular fire corridor the way inland Western cities do. But it's exactly the kind of out-of-nowhere event Canairy is built to catch: a plain-English alert when smoke drifts in from a thousand miles away, even on a day nothing in the local forecast would have warned you.
Newport News air quality FAQ
What is the air quality in Newport News right now?
This page shows the current AQI for Newport News, 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, whether that's downtown, Denbigh, or the East End.
Why does Newport News get hazy or smoggy in summer?
Hot, humid, and calm summer afternoons let vehicle exhaust from I-64 and I-664 and emissions from the region's shipyards and port terminals cook into ground-level ozone. It's the same chemistry that got Newport News classified as a marginal ozone nonattainment area for years — the city only reached maintenance status for the older federal ozone standards in 2007.
Did wildfire smoke ever reach Newport News?
Yes, briefly. During the extraordinary Canadian wildfire season of 2023, smoke drifted as far south as Virginia and affected air quality here on June 2, 2023. It was a rare event, not a recurring pattern — Newport News's ongoing air quality story is summer ozone, not wildfire smoke.
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 Newport News data come from?
Readings come from PurpleAir's network of laser particle sensors across Newport News 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.
