Air quality today

The air quality today in Tha Khlong Town Municipality is classified as Unhealthy. The primary pollutant identified is PM2.5, with a measured concentration of 77.7 µg/m³. A total of 21 valid measurements were recorded for the assessment.

PM10 levels are reported at 74.0 µg/m³, confirming fine particulate matter as the dominant concern. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Tha Khlong Town Municipality data set contains measurements for carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃) – although no O₃ values are reported in the latest rows – particulate matter of three size fractions (PM1, PM2.5 and PM10), relative humidity, sulfur dioxide (SO₂) – also not present in the recent records – temperature, and a particle count metric labelled UM003. The collection comprises 27 individual rows from four monitoring stations, but only 21 of those rows have been updated within the past seven days; six rows lack a timestamp and are therefore classified as unknown. The most recent update for any pollutant occurred on 2026‑02‑10 at 22:00 UTC.

Across the fresh records, PM2.5 shows a median concentration of 38.6 µg/m³ with values ranging from about 18.7 to 77.7 µg/m³; the interdecile spread (10th–90th percentile) runs from roughly 26.6 to 64.8 µg/m³, indicating moderate variability among sites. PM1 follows a tighter distribution, median 28.3 µg/m³ and extremes of 25.8 to 55.0 µg/m³, while PM10 is reported at only two stations with a median of 61.8 µg/m³ and a maximum of 74.0 µg/m³. Relative humidity in the recent data varies between about 43 % and 58 %, centering on a median of 44 %. Temperature readings span from 26.4 °C to 31.7 °C, with a typical value near 28.3 °C. The particle‑count metric UM003 ranges widely, from roughly 1 558 to 5 843 particles per cubic centimetre, median around 3 154.

CO and NO₂ are each represented by a single recent measurement, both constant at 0.5 ppm for CO and 0.0 ppm for NO₂, recorded at the Bangkok University Rangsit Campus. Because many pollutants (O₃, SO₂) have no current entries and several rows lack timestamps, the snapshot does not capture the full temporal or spatial picture of air quality in Tha Khlong Town. Consequently, conditions can differ across neighborhoods and times beyond what these recent values convey.
