This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Milton today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements from five monitoring points show a PM2.5 concentration of 25.0 µg/m³, which aligns with the reference value used for assessment.
Data are shown via OpenAQ and reflect the current conditions based on the available observations. 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 Milton air‑quality record is built from a single monitoring site that supplies five separate pollutant measurements. All of the data points were last refreshed on 2026‑02‑10 at 22:00 UTC, so the information reflects conditions captured within the past three days. Because there is only one sensor location, each pollutant appears as a single row rather than a spread across multiple stations.
The dataset includes nitrogen monoxide (NO) at 0.003 ppm, nitrogen dioxide (NO₂) at 0.016 ppm, total nitrogen oxides (NOX) at 0.019 ppm, ozone (O₃) at 0.034 ppm, and fine particulate matter (PM2.5) at 25.0 µg/m³. For each of these compounds the minimum, median and maximum values are identical, indicating that only one measurement is currently available for every pollutant. Consequently there is no observed variability or range within this snapshot; the reported figures represent the sole recent reading from Milton.
With just a single monitoring point, the coverage is limited to the conditions at that specific location and time. While the timestamps are current, the lack of additional rows means the dataset cannot capture spatial differences across the city or temporal changes throughout the day. Users should keep in mind that air‑quality can differ elsewhere in Milton, and the present numbers provide only a brief glimpse rather than a comprehensive picture.

Data notes
The current air‑quality summary for Milton is based on five valid measurements and was refreshed within the past three days, with the latest data logged at 2026‑02‑10 22:00 UTC. These values represent a snapshot of conditions across the monitoring network; actual pollutant levels can differ by neighbourhood and time of day, so local variations may occur even though the dataset is recent and complete.
