This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality today in Nonthaburi City Municipality is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 33.4 µg/m³ and a PM10 level of 61.0 µg/m³, based on six valid observations collected via OpenAQ.
These values reflect the current assessment for the city at this time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 OpenAQ feed for Nonthaburi City Municipality currently provides data on ten measured variables: carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃, written as O3), particulate matter of 1 µm (PM1), PM10, PM2.5 (written as pm25), relative humidity, sulfur dioxide (SO₂, written as SO2), temperature and a sensor labelled UM003. The dataset contains information from two monitoring stations, but the completeness varies by pollutant. For CO, NO₂, O₃, SO₂, PM10 and PM2.5 the latest readings were all recorded at 2026-02-10 22:00 UTC, so these six pollutants have fresh data that is less than a week old. In contrast, PM1 and relative humidity have no recent timestamps; their update status is listed as unknown, meaning the exact time of the last measurement cannot be determined from the feed.
Across the six regularly updated pollutants, the observed ranges are modest. CO values span 0.52 ppm to 0.70 ppm with a median of 0.61 ppm; NO₂ varies between 0.02 ppm and 0.045 ppm (median 0.0325 ppm); O₃ runs from 0.011 ppm up to 0.016 ppm (median 0.0135 ppm). Particulate matter shows a broader spread: PM10 ranges from 33 µg/m³ to 61 µg/m³ (median about 33.5 µg/m³) and PM2.5 from 16.3 µg/m³ to 33.4 µg/m³ (median 20 µg/m³). The 10th‑percentile values sit near the lower ends of these ranges, while the 90th‑percentile values approach the maximums, indicating that most recent measurements cluster toward the higher side of the observed spread for both PM10 and PM2.5.
Because only two stations contribute data, spatial coverage is limited; conditions can differ across neighborhoods even though the reported figures give a snapshot of city‑wide air quality at the time of the latest updates. The absence of recent timestamps for PM1 and relative humidity further reduces the completeness of the picture, so users should keep in mind that some aspects of the local environment may not be captured by the current dataset.

Data notes
The data shown reflects six valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. While this snapshot provides a current view of air quality across Nonthaburi City Municipality, conditions can differ by specific location and time of day within the city, so individual experiences may vary.
