Days with an AQI in 2025 (of 365)
In 2025, EPA reported a daily Air Quality Index (AQI) for Dougherty, Georgia on 365 days. 209 of those days (57%) were in the Good range, and the median daily AQI was 46. That median is about the same as the typical monitored county in Georgia (median 46 across 25 counties), and higher than the typical monitored U.S. county (40). The main pollutant was fine particles (PM2.5) on 365 days. Across the years with fuller monitoring, the share of Good days rose: an average of 25% in 2003–2009 versus 56% in 2023–2025.
Years with fewer than 120 monitored days (2001, 2002, 2004, 2005, 2006, 2007…) 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.
