Air quality today

The air quality in Langeberg Local Municipality is classified as Good today. The primary pollutant measured is PM2.5, with a recorded concentration of 1.51 µg/m³ based on five valid observations from OpenAQ data.

No other pollutants have been reported for this period, and the available measurements indicate that conditions remain within the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Langeberg Local Municipality draws from nine data rows collected at two monitoring stations. It includes measurements of PM2.5, PM1, PM10, relative humidity, temperature and particle concentration (UM003). The most recent timestamps are from 2026‑02‑10 18:00 UTC for five of the six pollutants, showing that the latest information is only a few days old. PM10 is an outlier, with its last update on 2025‑01‑13 23:00 UTC, meaning that this particular reading is over a year old.

PM2.5 values span from about 1.51 to 6.33 µg/m³, with a median of roughly 3.92 µg/m³, indicating modest variability across the recorded period. Relative humidity ranges between 53.9 % and 57.1 %, centering on a median of 55.5 %. Temperature shows a broader spread, from 22.27 °C up to 25.72 °C, with a typical value near 23.99 °C. In contrast, PM1, PM10 and UM003 each have a single recorded figure – 0.67 µg/m³ for PM1, 1.30 µg/m³ for PM10 and 374.5 particles/cm³ for UM003 – reflecting limited sampling for these parameters.

Overall the coverage is uneven: while PM2.5, humidity and temperature benefit from multiple recent observations, the other pollutants rely on a solitary data point, and one of those points is dated. Consequently, the picture of air quality in Langeberg is most reliable for the three well‑sampled variables, whereas conditions related to PM1, PM10 and particle concentration are based on sparse information and may not capture spatial or temporal variations across the municipality.

Data notes

The data shown reflects five valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑10 at 18:00 UTC. This snapshot provides a brief view of current conditions; however, air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in Langeberg Local Municipality.
