Air quality today

The air quality today in Kampala is classified as Unhealthy. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 55.80 µg/m³ based on thirty valid observations recorded by OpenAQ.

What the data includes

The dataset for Kampala includes six measured variables – PM2.5, PM10, PM1, relative humidity, temperature and the particle count UM003 – collected from a total of 62 individual rows representing 21 monitoring stations across the Central Region. Freshness varies markedly: none of the records were taken today or within the last three days, only 30 rows (about half) are dated within the past week, five more fall in the 7‑to‑30‑day window, one is older than a month and 26 rows have no timestamp at all. For each pollutant the most recent valid timestamps are from 2026‑02‑10 22:00 UTC, so the newest data are just over a week old.

Across the available observations PM2.5 values range from roughly 9 to 70 µg/m³ with a median of 40.6 µg/m³, indicating that half of the recent readings sit around that level while the spread reaches both low and high ends. PM10 shows a broader span, from about 4 to 89 µg/m³, with a median near 28.5 µg/m³; however only 13 rows contain this metric and its last‑update time is unknown, suggesting limited coverage. PM1 measurements are confined to seven recent rows, ranging between 16 and 38 µg/m³ and centering on a median of 34 µg/m³.

Relative humidity and temperature are both well represented (seven recent rows each). Humidity varies from 56 % to 89 %, median 81.6 %; temperature spans 20 °C to 30 °C, median 22.2 °C. The UM003 particle count also appears in seven fresh rows, ranging from roughly 1 000 to 3 500 particles per cm³ with a median of 2 436. Overall, while the dataset captures a useful snapshot of air‑quality related conditions in Kampala, the uneven number of records per pollutant and the presence of many unknown timestamps mean that conditions can differ noticeably across locations and times within the city.
