Air quality today

The current air quality in Klang Wiang is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 38.45 µg/m³ reported by OpenAQ.

Five valid measurements contribute to this assessment, confirming the presence of fine particulate matter at the stated level. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Klang Wiang dataset currently contains measurements from a single monitoring site, giving six rows of data that cover six different pollutants: PM1, PM10, PM2.5, relative humidity, temperature and UM003 (particle count). All values are reported as single observations rather than ranges; for each pollutant the minimum, median and maximum are identical because only one recent reading is available.

Freshness varies across the parameters. The most up‑to‑date entries were recorded on 2026‑02‑10 at 22:00 UTC for PM1 (25.68 µg/m³), PM2.5 (38.45 µg/m³), relative humidity (66.86 %), temperature (20.93 °C) and UM003 (5 257.28 particles/cm³). The PM10 reading is older, last updated on 2025‑01‑13 at 23:00 UTC with a value of 43.55 µg/m³. This means that five of the six pollutants have data from within the past week, while one pollutant relies on information that is more than a year old.

Because the dataset consists of a single location, it provides only a snapshot of conditions at โรงเรียนราชประชานุเคราะห์ 56 and does not capture spatial variation across Klang Wiang. The uniformity of the reported values (each statistic equal to the same number) reflects the limited temporal depth—there is no historical spread to describe typical fluctuations over time. Consequently, while recent readings give a clear picture of the current state for most pollutants, the older PM10 figure highlights that not all parameters are refreshed with the same frequency, and city‑wide air quality can differ from what this single point measurement shows.

Data notes

The data shown for Klang Wiang is based on five valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T22:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may vary from one location or moment to another.
