Air Quality in Wichita, Kansas — Live

Live readings from PurpleAir sensors across Wichita — with free alerts when spring smoke or summer ozone push the air into unhealthy territory.

Live Wichita AQI from nearby PurpleAir sensors loads when this page opens in a browser, along with a live sensor map covering Wichita and Derby, Andover, Haysville, Park City.

Wichita's air is Good or Moderate most of the year, but two very different stretches change that. In late March and April, ranchers across the Flint Hills just east of the city burn hundreds of thousands of acres of tallgrass prairie to keep it healthy for cattle grazing, and when the wind comes out of the east that smoke settles right over the metro. Then, from March through October, the city runs its own separate ozone season — hot, still summer afternoons cook vehicle exhaust into ground-level ozone that can push the AQI into unhealthy territory for people with asthma, even on a day with clear blue skies.

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.

Flint Hills burning is a real spring event, not a rumor

Each year in late March and into April, ranchers across the Flint Hills — the belt of rocky, unplowed tallgrass prairie that runs along Wichita's eastern edge and holds the largest remaining stretch of tallgrass prairie in North America — deliberately burn large sections of it. The fire clears dead grass, knocks back invasive trees, and makes the new growth better cattle forage. Wichita sits close enough to the western edge of that same prairie that when the wind blows from the east, smoke from those burns drifts straight into the city rather than staying out in open country.

The state takes this seriously enough to run a dedicated Flint Hills Smoke Management Plan through KDHE, with a daily forecast map at ksfire.org that shows land managers where their smoke is likely to land on a given day. It doesn't always work out — the Wichita Eagle and KSN have both reported air quality advisories covering central and eastern Kansas during peak burning weeks, with KDHE urging people to limit outdoor activity while burning-driven pollutant levels are elevated across the region.

Wichita runs its own ozone season, March through October

Unlike the spring smoke, ozone is a summer, sunny-day problem — vehicle exhaust and other emissions cook into ground-level ozone in strong heat and light, and Wichita's ozone season officially runs March 1 through October 31. The city's Ozone Alerts program, run out of wichita.gov, covers the whole Wichita metro area — Sedgwick, Butler, Harvey, and Sumner counties — and is triggered by a mix of high heat, ozone carried over from the day before, high ozone arriving from upwind, and stagnant wind conditions that let it build up instead of clearing out.

The city's Be Air Aware campaign, a joint effort with the EPA and KDHE, asks residents to do specific things on alert days: carpool or take the bus, refuel after 6pm, skip the gas mower, cut down on idling, and put off anything involving paint or solvent fumes until the alert passes. It's a voluntary program rather than a shutdown order, but its existence is a sign of how often summer heat here actually pushes ozone into a range worth planning around.

Spring pollen compounds the problem

The same spring stretch that brings Flint Hills smoke also brings the country's toughest allergy season by at least one measure: the Asthma and Allergy Foundation of America's 2023 Allergy Capitals report ranked Wichita the single hardest U.S. city to live in with pollen allergies, giving it a perfect score of 100 against a national average of 71.49 — and Kansas.com reported it was the second year running Wichita had topped the list. Tree and grass pollen off the surrounding plains and pastureland drives most of that score.

Pollen and PM2.5 are measured differently and Canairy's numbers are about particle pollution, not pollen counts — but the timing overlap matters. Someone with asthma or seasonal allergies in Wichita can be dealing with high pollen, wafting field-burning smoke, and the season's first warm-weather ozone spikes all in the same few weeks, which is exactly the stretch worth watching your saved locations most closely.

Wichita air quality FAQ

What is the air quality in Wichita right now?

This page shows the current AQI for Wichita, 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 Wichita smell smoky in late March and April?

That's Flint Hills prescribed burning — ranchers across the tallgrass prairie just east of the city set fire to hundreds of thousands of acres each spring to keep it healthy for grazing. When the wind blows from the east, that smoke drifts into Wichita, and KDHE has issued air quality advisories for central and eastern Kansas during peak burning weeks.

Does Wichita have a summer ozone problem?

Yes. The city runs an official Ozone Alerts program from March 1 through October 31, covering the whole Wichita metro area. Alerts go out when heat, stagnant wind, and vehicle emissions combine to push ground-level ozone into unhealthy territory, and the city's Be Air Aware campaign asks residents to carpool, refuel after 6pm, and cut back on driving on those days.

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.

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.

Where does Canairy's Wichita data come from?

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