Air quality today
The air quality in Saraburi is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 34.5 and a PM10 reference value of 74.0, based on two valid observations.
Data are shown via OpenAQ. 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 data set for Saraburi includes measurements of four pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10) and particulate matter ≤2.5 µm (PM2.5). All values come from a single monitoring location, the Khao Noi Fire Station, so the city’s air‑quality picture is based on one row of data for each pollutant.
The timestamps show an uneven mix of recency. The most recent updates are for PM10 and PM2.5, both recorded at 2026-02-10 22:00 UTC, which means those particulate readings are current within the last week. In contrast, the gas‑phase measurements are older: NO₂ was last reported on 2023-07-25 00:00 UTC and O₃ on 2021-12-05 11:00 UTC, indicating that the latest available information for these gases is several months to years out of date.
All four pollutants have a single recorded value, with the minimum, median and maximum being identical. NO₂ registers at 0.0 ppm, O₃ at 0.087 ppm, PM10 at 74.0 µg/m³ and PM2.5 at 34.5 µg/m³. Because there is no spread in the data, the reported figures represent the sole observation for each pollutant rather than a range of conditions.
Given that only one monitoring site contributes to the dataset, spatial variation across Saraburi cannot be captured, and the older timestamps for NO₂ and O₃ mean those gases may have changed since the last measurement. Users should keep in mind that the city’s air quality can differ by location and time, especially for pollutants where recent data are lacking.

Data notes
The data shown for Saraburi reflects two valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC, meaning it is updated within three days. This snapshot provides a brief view of current conditions, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
