Most of the year, the air over Bellevue is unremarkable in the best sense — Sarpy County isn't wildfire country, and there's no refinery or mill next door dominating a local pollution story. The real story here is regional: the whole Omaha–Council Bluffs metro area sits close enough to the federal ozone limit that a regional planning agency runs an ongoing public campaign just to help keep it there, which is why the numbers on a hot, still July afternoon are worth checking even when nothing nearby looks obviously wrong.

Bellevue's real air story is regional ozone, not local smoke
The Metropolitan Area Planning Agency (MAPA), which handles air-quality planning for the Omaha–Council Bluffs region, has measured the area's ground-level ozone at 67 parts per billion — just three points under the 70 ppb standard the EPA set on October 1, 2015. That narrow margin is why MAPA runs Little Steps. Cleaner Air., an ongoing public program built specifically to help keep the metro, Bellevue included, from tipping into official nonattainment, since crossing that line would trigger new federal planning and permitting requirements for the whole region.
Ozone isn't released directly from a pipe or stack; it forms when vehicle exhaust and other emissions cook in strong sun and summer heat, which makes it a whole-metro phenomenon rather than something tied to one address. That's exactly why Bellevue's numbers tend to move together with Omaha's on hot, sunny, windless days in July and August — the pollutant is regional even though the reading you check is local.
A river town built around a base, not a smokestack
Bellevue is the oldest continuously inhabited town in Nebraska, founded as a fur-trading post in the 1830s and incorporated in 1855, and it sits on bluffs above the Missouri River, which forms the city's eastern edge. What has shaped its profile more than any industry is Offutt Air Force Base, built just south of the city in 1921 and now home to US Strategic Command — Bellevue's economy centers on the base and the wider Omaha job market rather than on the kind of refinery, mill, or plant that gives some cities a distinct local pollution signature.
The bigger environmental drama here has actually been water, not air: the 2019 Missouri River floods destroyed roughly 200 homes in Bellevue and put almost half of Offutt's runway under water, forcing flight operations to move temporarily to Lincoln. It's a reminder that the river-valley setting cuts both ways — the same bluffs and floodplain that give Bellevue its name and its views are also why flooding, not wildfire smoke, is the natural hazard longtime residents actually plan around.
Bellevue air quality FAQ
What is the air quality in Bellevue right now?
As of September 14, 2026 at 4:09 PM CDT, the air quality in Bellevue, Nebraska is AQI 40 — Good — with PM2.5 at 7.2 µg/m³, the median of 4 live PurpleAir sensors. Open the windows. Great for outdoor activity.
Why does Bellevue's air quality get worse in summer?
Ground-level ozone is the Omaha–Council Bluffs area's real air-quality challenge, and it peaks on hot, sunny, windless days from roughly June through August. The region measures around 67 ppb against the federal 70 ppb standard, a margin close enough that MAPA, the regional planning agency, runs an ongoing public program to help keep it there. Because ozone forms metro-wide rather than at a single source, Bellevue's readings tend to track the rest of the Omaha area on these days.
Does Offutt Air Force Base affect Bellevue's air quality?
There's no documented evidence that Offutt Air Force Base, just south of the city, is a major driver of Bellevue's day-to-day air quality — the base's footprint is more about jobs and history, as home to US Strategic Command, than industrial emissions. The bigger environmental risk tied to the base's location has been flooding: the 2019 Missouri River floods put nearly half its runway under water.
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 Bellevue, 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.
