Air quality today

The air quality today in San Pong is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 38.77 µg/m³ based on 40 valid observations collected via OpenAQ.

These data reflect the current state of ambient air without additional interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The San Pong dataset contains six measured pollutants: PM1, PM2.5, PM10, relative humidity, temperature and UM003 (particle concentration). The data come from a total of twelve rows for most variables, but only ten rows are available for PM10, reflecting slightly uneven coverage across the pollutant set. Freshness varies by parameter: the newest readings for relative humidity, temperature, PM1, PM2.5 and UM003 were all recorded on 2026‑02‑10 at 22:00 UTC, while the most recent PM10 value dates back to 2025‑01‑13 at 23:00 UTC, indicating that PM10 information is considerably older than the other metrics.

Across the recent observations, relative humidity spans from about 31 % up to a high of 86.9 %, with a median near 63 %. Temperature ranges between roughly 20 °C and 33 °C, centering on a median of 21.7 °C. PM1 values show a broad spread, from just above zero to 79.3 µg/m³, with the typical (median) level around 21.2 µg/m³; the 10th‑percentile is near 1.7 µg/m³ and the 90th‑percentile reaches about 23.9 µg/m³. PM2.5 exhibits a similar breadth, from 0.17 to 136.4 µg/m³, median 33.9 µg/m³, with the central 80 % of values lying between roughly 3.6 and 38.7 µg/m³. UM003 particle counts vary widely, from about 90 particles/cm³ up to nearly 19,800 particles/cm³, with a median of 2,374 particles/cm³; most readings fall between 491 and 4,656 particles/cm³.

Because the dataset includes only a handful of recent rows for each pollutant—and especially because PM10 data are more than a year old—conditions in San Pong can differ across locations and times that are not captured here. Users should keep in mind that the available numbers represent snapshots from limited monitoring points rather than a comprehensive, continuously updated picture of air quality throughout the city.

Data notes

The data shown for San Pong reflects 40 valid measurements and is Updated within 3 days, with the most recent reading recorded at 2026‑02‑10T22:00:00+00:00. This snapshot provides a current view of air quality across the city, but conditions can differ by neighbourhood and time of day, so values may vary locally even though the overall dataset is recent and reliable.
