Air quality today
The air quality in Bayonne today is classified as Good. The primary pollutant measured is PM10, with a reported reference value of 7.7 µg/m³ based on three valid observations.
Data are shown via OpenAQ and reflect the current monitoring results 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 Bayonne air‑quality dataset currently contains eight measurement rows drawn from two monitoring sites. Four key pollutants are reported: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter ≤ 10 µm (PM10). The most recent observations are fairly current for three of the gases, with NO₂ and O₃ both last updated on 2026‑02‑10 at 15:00 UTC and PM10 on 2026‑02‑09 at 03:00 UTC. The NO record is older, its latest entry dated 2024‑03‑11 at 09:00 UTC, so the nitrogen monoxide data are less fresh than the others.
Across the eight rows, the measured concentrations show modest variability. For NO the values range from a low of 3.2 µg/m³ to a high of 3.6 µg/m³, with a median around 3.4 µg/m³. NO₂ spans 10.3 to 14.6 µg/m³, median 12.45 µg/m³, while O₃ is tightly clustered between 50.5 and 52.0 µg/m³, median 51.25 µg/m³. PM10 exhibits the widest spread, from 2.4 up to 7.7 µg/m³, with a median of 5.05 µg/m³. The 10th‑percentile values are close to the minima for each pollutant, and the 90th‑percentile values sit near the maxima, indicating that most observations fall within a narrow band around the typical levels.
Because only two stations contribute data, spatial coverage is limited; conditions measured at SAINT‑CROUTS may not represent the whole city at any given moment. The dataset includes a mix of recent and older entries—most rows are fresh (updated within the past week), but the NO series remains dated. Users should keep in mind that air quality can differ across neighborhoods and over time, and the available data provide a snapshot rather than a complete picture of Bayonne’s atmospheric state.

Data notes
The dataset for Bayonne contains three valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 15:00 UTC; it is therefore considered Updated within 3 days. These values represent a snapshot of ambient conditions at the time of sampling. Please note that air quality can vary across different neighborhoods and times of day within the city, so this information reflects only the specific measurement period.
