Days with an AQI in 2025 (of 365)

In 2025, EPA reported a daily Air Quality Index (AQI) for Murray, Georgia on 257 days. 232 of those days (90%) were in the Good range, and the median daily AQI was 39. That median is lower than the typical monitored county in Georgia (median 46 across 25 counties), and about the same as the typical monitored U.S. county (40). The main pollutant was ozone on 225 days. Across the years with fuller monitoring, the share of Good days rose: an average of 49% in 2000–2002 versus 86% in 2023–2025.

EPA did not report an AQI for every day of 2025 here (257 of 365 days). Figures describe monitored days only; seasonal monitoring (for example, ozone measured only in warmer months) can make a county look cleaner or dirtier than a full-year record would.

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.
