Days with an AQI in 2025 (of 365)

In 2025, EPA reported a daily Air Quality Index (AQI) for Manatee, Florida on 365 days. 332 of those days (91%) were in the Good range, and the median daily AQI was 36. That median is lower than the typical monitored county in Florida (median 41 across 38 counties), and lower than the typical monitored U.S. county (40). The main pollutant was ozone on 365 days. Across the years with fuller monitoring, the share of Good days fell: an average of 98% in 1980–1982 versus 92% in 2023–2025.

Years with fewer than 120 monitored days (1983, 1989) are shown in the table but left out of comparisons and trend statements.

How the days broke down each year

Each bar is one year. The colored segments show the share of monitored days that fell in each AQI category.

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.
