Air Quality in Lincoln, Nebraska — Live

Live readings from PurpleAir sensors across Lincoln — with free alerts when Flint Hills smoke or summer ozone rolls in.

Live Lincoln AQI from nearby PurpleAir sensors loads when this page opens in a browser, along with a live sensor map covering Lincoln and Waverly, Hickman, Malcolm, Raymond.

Lincoln's air is genuinely good most of the year. Lancaster County earned a B grade in the American Lung Association's most recent State of the Air report, with a median AQI of 41 and zero unhealthy or hazardous days recorded across ten years of monitoring — helped along by Nebraska's near-constant Plains wind, which tends to flush out pollution before it can sit still and build up. The exception lands every spring, when smoke from prescribed rangeland burning hundreds of miles south, in the Flint Hills of Kansas and Oklahoma, drifts north on the wind and can turn a clear Lincoln morning hazy by afternoon.

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 Lincoln's air is clean most days

Lincoln doesn't have the refineries, ports, or dense freeway stacks that give some cities a year-round pollution baseline. The city's own power plant, Lincoln Electric System's Terry Bundy Generating Station, runs on natural gas rather than coal. Combined with Nebraska's spot in the Great Plains wind corridor — among the windiest parts of the country outside the Rockies — pollution that does form usually gets flushed out before it can build into the kind of stagnant haze that settles over cities boxed in by mountains or river basins.

That shows up in the numbers. Lancaster County, Lincoln's home county, posted a B grade in the American Lung Association's most recent State of the Air report, with 83.8 percent good air-quality days and no unhealthy or hazardous days at all across the ten-year period measured. The one pollutant the report flags as the county's dominant concern is ground-level ozone, not soot or smoke — a summer-heat problem that runs moderate far more often than it turns unhealthy here.

Every spring, smoke arrives from three states away

The Lincoln-Lancaster County Health Department tells residents to watch air quality closely for an eight- to ten-week stretch each spring, because smoke from controlled burning across the southern and central United States can drift into southeast Nebraska even when there's no fire anywhere near the city. The source is the Flint Hills of Kansas and Oklahoma, where ranchers set fire to tens of thousands of acres of tallgrass prairie every March and April to clear dead growth and hold back invasive trees before cattle go out to graze.

It isn't hypothetical. Nebraska's Department of Health and Human Services issued a smoke advisory covering southeastern Nebraska, including both Lincoln and Omaha, for March 21–22, 2026, warning that Flint Hills burn smoke could push air quality to Moderate and periodically Unhealthy for Sensitive Groups. The fires can be three states away and still put a haze over the Capitol dome — exactly the kind of event a citywide forecast can miss and a live sensor reading catches.

Lincoln runs its own air program, and watches harvest dust too

Unlike most of Nebraska, Lincoln doesn't rely solely on the state to watch its air. The Lincoln-Lancaster County Health Department is one of only three local agencies in Nebraska — alongside Omaha Air Quality Control and the Douglas County Health Department — delegated to run its own program, continuously monitoring carbon monoxide, tracking ozone seasonally, and periodically testing for PM2.5. Open burning inside city limits requires a permit under Lincoln Municipal Code 8.06 and county resolution R-13-0073, because backyard and brush burning is still a real local source of smoke here.

The other seasonal wildcard is dust. Lincoln sits inside some of the most productive corn and soybean ground in the country, and in a dry harvest — like fall 2024, when combines were kicking up thick clouds of dust across Nebraska as more than 80 percent of the soybean crop came in during one of the driest harvests farmers could remember — that dust can blend with any drifting wildfire smoke to dull the air on the city's farm-country edges well into October.

Lincoln air quality FAQ

What is the air quality in Lincoln right now?

This page shows the current AQI for Lincoln, 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.

Why does Lincoln get smoky or hazy in early spring?

Most years, the Lincoln-Lancaster County Health Department flags an eight- to ten-week window each spring, roughly March into April, when smoke from prescribed rangeland burns in the Flint Hills of Kansas and Oklahoma can drift north into southeast Nebraska. Nebraska's own health department issued a smoke advisory for Lincoln and Omaha on March 21–22, 2026 for exactly this reason. The fires are hundreds of miles away, but the smoke is real and can push a normally clear day into Moderate or Unhealthy for Sensitive Groups.

Does Lincoln have industrial air pollution?

Not much. Lincoln's own power plant runs on natural gas rather than coal, and the city has little of the heavy industry that drives year-round pollution elsewhere. Lancaster County earned a B grade in the American Lung Association's most recent State of the Air report, with ground-level ozone — a summer-heat problem, not a soot problem — flagged as the area's main pollutant.

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 Lincoln data come from?

Readings come from PurpleAir's network of laser particle sensors across Lincoln 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.

Is Canairy free?

Yes. The Canairy app is free to download and includes live air quality for all your saved places, plain-English verdicts, and free push alerts when the air crosses your threshold. A paid plan adds extras like SMS text alerts.
