Air quality today
The air quality in Baldwin County, Alabama is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 11.0 µg/m³. PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometers or less. No PM10 value is available for this assessment.
A single valid measurement underlies this assessment, and the data is shown via OpenAQ. Only one measurement met the validation criteria for inclusion. The single observation was recorded at the time of data collection and reflects the current ambient level. OpenAQ aggregates measurements from participating monitoring stations. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Baldwin County, Alabama currently provides measurements for two pollutants: ozone (O3) and fine particulate matter (PM2.5). Both values come from a single monitoring location identified as FAIRHOPE, giving a total of two data rows in the OpenAQ feed for the county. No additional stations or alternative sites are represented, so the coverage is limited to this one point for each pollutant.
The timestamps show that the most recent observation in the set is the PM2.5 reading from 2026-01-24 14:00 UTC, while the ozone measurement dates back to 2025-11-03 15:00 UTC. Because both rows are classified as “old” in the source metadata, the overall freshness of the data leans toward the earlier part of the last year, with only the PM2.5 value being less than a month old at the time of writing. This means that, for Baldwin County, the newest available snapshot of ambient air quality is from late January 2026, and the ozone data is more than three months older.
Each pollutant is represented by a single constant value: ozone registers at 0.028 ppm and PM2.5 at 11.0 µg/m³, with the minimum, median and maximum all identical for each series. The lack of multiple observations eliminates any observable spread or variability within the dataset, reinforcing the limited temporal depth. Because the data comes from only one location and the timestamps are largely dated, it should be understood that actual conditions across Baldwin County can differ by neighborhood and time of day, and the current figures capture only a narrow slice of the broader air‑quality picture.
