Air Quality in Chesapeake, Virginia — Live
Live readings from PurpleAir sensors across Chesapeake — with free alerts the moment the air changes enough to matter.
AQI 48 from 4 PurpleAir sensors · Trending down · data from PurpleAir
As of , the air quality in Chesapeake, Virginia is AQI 48 — Good and falling — with PM2.5 at 8.6 µg/m³, the median of 4 live PurpleAir sensors reading 36 to 49. Canairy's verdict: Breathe easy.
For scale, that PM2.5 reading is below the World Health Organization's 24-hour guideline of 15 µg/m³. The WHO figure is a daily average and this is a live reading, so read it as a sense of magnitude rather than a formal exceedance — a brief spike and a bad day are not the same thing.

Sensor by sensor in Chesapeake
The sensors Canairy reads in Chesapeake agree right now — all 4 sit in the Good band, a 13-point spread — so the city-wide number is a fair description of the whole area today.
| From city center | AQI | Category |
|---|---|---|
| 1.8 mi ESE | 48 | Good |
| 4.3 mi N | 44 | Good |
| 5.3 mi N | 36 | Good |
| 6.1 mi N | 49 | Good |
Chesapeake's air is good most days — this is a humid, water-logged corner of Virginia, not smoke country. But part of the Great Dismal Swamp sits inside the city itself, and when that swamp's peat soil dries out and catches fire, as it did for 111 days in 2011, the smoke doesn't stay in the refuge. It settles over the whole Hampton Roads region, including Chesapeake's own neighborhoods, and it isn't the only source worth watching — hot summer ozone and smoke drifting down from Canadian wildfires have both pushed the air here into unhealthy territory in recent years.

The Great Dismal Swamp reaches into Chesapeake's own city limits
Chesapeake shares the Great Dismal Swamp National Wildlife Refuge with Suffolk and two North Carolina counties, and the swamp's northeastern corner lies inside the city itself. In August 2011, lightning struck deep in the refuge and ignited the Lateral West Fire, a peat fire that burned for 111 days — surviving a direct hit from Hurricane Irene without being extinguished — and blackened more than 6,300 acres before crews finally got it out.
Peat doesn't burn like a forest fire; it smolders underground in soil that had been drying out since an earlier 2008 fire killed the vegetation on top of it. That makes for thick, lingering smoke rather than a quick blaze, and Virginia's Department of Environmental Quality issued Code Orange and Code Red air quality alerts across Hampton Roads that August, warning anyone with asthma or heart disease to cut back on outdoor activity while some mornings brought near-zero visibility to the region.
Chesapeake's other air problem used to be summer ozone, not smoke
Long before wildfire smoke was the recognizable story, Hampton Roads — the metro area that includes Chesapeake, Norfolk, Virginia Beach, and Suffolk — was formally designated a marginal nonattainment area for ground-level ozone under the EPA's 1997 standard. Hot, humid, windless summer afternoons let vehicle and industrial exhaust cook into ozone faster than it can disperse, and Chesapeake's stretch of I-64 and I-464 carries some of the heaviest traffic in the region.
Virginia's environmental regulators successfully petitioned to redesignate Hampton Roads to attainment status in the mid-2000s, and the region has stayed in compliance since as a maintenance area. But the underlying weather pattern didn't go anywhere — the same still, humid, high-pressure days that build ozone in July and August are still a normal part of a Chesapeake summer, which is why the worst readings here tend to land on windless afternoons rather than during a storm.
Smoke has also drifted in from wildfires nowhere near Virginia
In June 2023, Hampton Roads found out its air doesn't only depend on what's burning nearby. Smoke from wildfires burning in Quebec and Nova Scotia drifted down the Atlantic seaboard, and on June 7 the National Weather Service office in Wakefield and Virginia's DEQ issued a Code Orange air quality alert for fine particulates across the region — the same pollutant category the Great Dismal Swamp fires produce, just from a source hundreds of miles away.
Local recreation leagues noticed before most residents did: youth soccer, softball, and tennis activities across Hampton Roads were suspended or rescheduled that week on DEQ's advice to shorten outdoor exertion whenever the sky looked smoky. It's a reminder that a clear local forecast doesn't guarantee clean air — which is exactly why Canairy reads live sensors instead of a weather forecast.
Chesapeake air quality FAQ
What is the air quality in Chesapeake right now?
As of September 14, 2026 at 9:28 PM EDT, the air quality in Chesapeake, Virginia is AQI 48 — Good — with PM2.5 at 8.6 µg/m³, the median of 4 live PurpleAir sensors. Open the windows. Great for outdoor activity.
Why did the Great Dismal Swamp fire affect Chesapeake's air?
The swamp's northeastern edge lies inside Chesapeake, and the 2011 Lateral West Fire there burned underground in dried peat for 111 days, producing thick smoke that Virginia's DEQ tracked with Code Orange and Code Red air quality alerts across the whole Hampton Roads region, not just the area immediately around the fire.
Does wildfire smoke from Canada reach Chesapeake?
Yes. In June 2023, smoke from wildfires burning in Quebec and Nova Scotia drifted down the Atlantic coast and triggered a Code Orange air quality alert across Hampton Roads, including Chesapeake, even though nothing was burning anywhere nearby.
What the AQI numbers mean
| AQI | Category | What it means for you |
|---|---|---|
| 0–50 | Good | Open the windows. Great for outdoor activity. |
| 51–100 | Moderate | Sensitive groups may want to take it slower outside. |
| 101–150 | Unhealthy for Sensitive Groups | Kids, elderly, and respiratory conditions stay closer to home. |
| 151–200 | Unhealthy | Skip outdoor exercise. Close windows. |
| 201–300 | Very Unhealthy | Limit time outside. N95 if you must go. |
| 301+ | Hazardous | Health emergency. Stay inside, run filtration if you have it. |
Canairy lets you tighten these bands if you’re more sensitive than the EPA default, so an alert can fire before the official category changes. How to read the Air Quality Index
Where these readings come from
The AQI at the top of this page is the median of the 4 curated PurpleAir sensors Canairy tracks in and around Chesapeake, with outliers set aside so that one sensor brought indoors — or parked beside a barbecue — cannot set the number for a whole city. Every sensor behind it is listed above with its distance and bearing from the city center. There is no black box here.
In the app, a place you save resolves the same way first. When no neighborhood sensor is reporting it falls back to the nearest EPA AirNow monitor, and anything modeled rather than measured is labelled a regional estimate rather than passed off as a sensor reading.
