Air quality today
The air quality in Fréjus today is classified as Good. The primary pollutant measured is PM2.5, with a reference concentration of 8.7 µg/m³, while the accompanying PM10 level stands at 10.3 µg/m³ based on four valid observations.
Data are shown via OpenAQ and reflect the current assessment for this location. 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 Fréjus contains measurements from a single monitoring location, providing five separate data rows—one for each of the pollutants tracked in this city. The available pollutants are nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5).
The most recent observations are fairly current for the gases, with NO₂ and O₃ both recorded at 2026‑02‑10 15:00 UTC, while the nitrogen monoxide reading dates back to 2024‑03‑11 09:00 UTC. The particulate measurements are slightly older, last updated on 2026‑02‑09 03:00 UTC for both PM10 and PM2.5. Across all five pollutants the median values are identical to their minimum and maximum because each series contains a single reported figure: NO at 2.9 µg/m³, NO₂ at 8.0 µg/m³, O₃ at 46.0 µg/m³, PM10 at 10.3 µg/m³ and PM2.5 at 8.7 µg/m³. This uniformity indicates that the current snapshot does not capture variability over time; there is no spread of values to describe fluctuations within the reporting period.
Because only one monitoring site contributes data, spatial coverage across Fréjus is limited, meaning conditions can differ in other neighborhoods or at different times of day. The freshness of the gas measurements is good, being updated within the last few days, whereas the older NO reading and the particulate data, though still recent, are a few days behind. Users should keep in mind that this single‑point snapshot offers a narrow view of air quality for the city at the recorded moments.
