Air quality today

The air quality in Kuala Lumpur today is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 21.47 µg/m³ based on seven valid observations reported through OpenAQ.

Data indicate that fine particulate matter dominates the current profile, while no reference value for PM10 is available. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Kuala Lumpur air‑quality feed currently includes six measured variables – PM1, PM2.5, PM10, relative humidity, temperature and UM003 (particle count). Data come from nine rows representing four distinct monitoring stations across the city. The most recent readings are all from 2026‑02‑10 16:00 UTC or later, except for PM10 which was last updated on 2025‑01‑13 23:00 UTC, indicating that five of the six pollutants have fresh data within the past few days while one remains over a year old.

Across the available rows, PM2.5 values range from a low of 21.47 µg/m³ to a high of 45.91 µg/m³, with a median of 34.53 µg/m³, showing moderate variability between locations. In contrast, PM1 and UM003 each have a single reported value – 29.49 µg/m³ for PM1 at Taman Tun Dr. Ismail and 6 405.13 particles/cm³ for UM003 at the same site – so no spread can be assessed for those metrics. Relative humidity is consistently recorded at 53.56 % and temperature at 28.34 °C, both from the Taman Tun Dr. Ismail station, indicating uniform conditions in that micro‑area at the time of measurement.

The dataset’s composition highlights uneven coverage: while PM2.5 benefits from four recent observations, PM10 relies on a solitary older record, and several parameters are represented by only one station. Consequently, city‑wide air quality snapshots may differ markedly between neighborhoods and times, especially for pollutants with limited or dated data.

Data notes

The data shown reflects seven valid measurements and is updated within three days, with the most recent reading recorded at 2026‑02‑10T16:01:30+00:00. These figures provide a current snapshot of air quality across Kuala Lumpur, but conditions can differ by specific neighbourhoods and times of day, so local variations may not be captured in this summary.
