Days with an AQI in 2013 (of 365)

In 2013, EPA reported a daily Air Quality Index (AQI) for Wichita, Texas on 345 days. 270 of those days (78%) were in the Good range, and the median daily AQI was 35. That median is lower than the typical monitored county in Texas (median 43 across 41 counties), and lower than the typical monitored U.S. county (42). The main pollutant was fine particles (PM2.5) on 345 days. Across the years with fuller monitoring, the share of Good days rose: an average of 63% in 2005–2007 versus 75% in 2011–2013.

The most recent year with data for this county is 2014; EPA's files for 2015–2025 contain no row for it, which usually means its monitors stopped reporting.

Years with fewer than 120 monitored days (1992, 1993, 1994, 1995, 1996, 2014…) are shown in the table but left out of comparisons and trend statements.

What this data can and can’t tell you

It is a county-level summary. EPA reports one AQI per day for the county, based on the monitors operating there. Air at a particular street, school or home can differ, especially near roads, industry or wildfire smoke.

It is not a health assessment. The AQI is EPA’s scale for communicating daily air quality. A county’s history can’t tell you what the health risk is for any particular person. For daily conditions and health guidance, see AirNow.

Rules change over time. EPA has revised AQI breakpoints, most recently for fine particles in 2024, so some year-to-year change can reflect the scale rather than the air.
