Air quality today

The air quality in Uithoorn today is classified as Unhealthy. The primary pollutant identified is PM2.5, with a measured concentration of 61.42 µg/m³ based on five valid observations reported through OpenAQ.

Data for this assessment are limited to the available PM2.5 reading; no PM10 value is provided. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Uithoorn air‑quality dataset contains six measured variables – PM1, PM10, PM2.5, relative humidity, temperature and the particle counter UM003 – all recorded at a single monitoring site identified as Uithoorn‑02. Because there is only one row of data, the station coverage for this city is limited to that single location.

The most recent observations are fairly fresh for five of the six pollutants, with the latest timestamps on 2026‑02‑05 00:00 UTC for PM1 (32.87 µg/m³), PM2.5 (61.42 µg/m³), relative humidity (71.15 %), temperature (4.91 °C) and UM003 (4 650.52 particles/cm³). The PM10 value is older, last updated on 2025‑01‑13 23:00 UTC at 65.19 µg/m³, which means the dataset includes one measurement that is more than a year out of date.

All six parameters show identical minimum, median and maximum values because each pollutant has only a single recorded point. Consequently there is no observed spread or variability within the data itself; the reported figures represent both the typical and extreme values for the site on those dates. The particle count UM003, expressed in particles per cubic centimetre, aligns with the particulate matter concentrations, while relative humidity sits at 71 % and temperature near 5 °C, reflecting the conditions at the time of measurement.

Overall, the dataset provides a snapshot rather than a continuous record: one recent reading for most pollutants, one older reading for PM10, and no additional rows to illustrate temporal changes. Users should keep in mind that air‑quality conditions can differ across neighborhoods and over time, and the limited coverage here may not capture those variations fully.
