Air quality today
The air quality in Wang Sai is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 31.65 µg/m³ based on five valid observations reported through OpenAQ.
Data for this assessment come from five recent measurements, and no PM10 value is available. 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 Wang Sai contains a single monitoring location, Baan Kut Ngong, which supplies one row of measurements for each of the five tracked variables: PM1, PM2.5, relative humidity, temperature and UM003 (particle concentration). All values were recorded at the same moment on 2026‑02‑10 22:00 UTC, so the freshest data available are just over a week old, meeting the “updated within 7 days” criterion for every pollutant.
PM1 is reported as 21.8835 µg/m³ and PM2.5 as 31.6530 µg/m³, both with identical minimum, median and maximum values because only one observation exists. Relative humidity stands at 54.19 % and temperature at 21.46 °C, again each showing a single recorded figure. The UM003 count is 1 293.90 particles per cubic centimetre, likewise without variation across the dataset.
Because there is only one station row, the data provide no range or spread for any pollutant; the reported minimum, median and maximum are all the same. This limits the ability to describe typical fluctuations over time or space within Wang Sai. Nevertheless, the presence of both fine‑particle metrics (PM1 and PM2.5) together with a particle number concentration (UM003), plus basic meteorological parameters, gives a modest but complete snapshot of air quality at that moment. Users should keep in mind that conditions can differ across neighborhoods and change rapidly, so this single‑point record represents only the state of the atmosphere at Baan Kut Ngong on 2026‑02‑10 22:00 UTC.

Data notes
The data shown for Wang Sai reflects five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is considered “Updated within 3 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 vary from one location or time to another.
