Air quality today

The air quality today in Riyadh governorate is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 17.46 µg/m³ based on five valid readings reported through OpenAQ.

What the data includes

The dataset for Riyadh governorate contains six measurement rows drawn from a single monitoring station. All six pollutants are represented: fine particles (PM1 at 6.59 µg/m³), coarse particles (PM10 at 51.19 µg/m³), PM2.5 at 17.46 µg/m³, relative humidity at 23.08 %, temperature at 24.81 °C, and ultrafine particle count (UM003) at 625.20 particles/cm³. For five of the pollutants the most recent reading was taken on 2026‑02‑10 22:00 UTC, showing that the data are generally fresh within the last week. The PM10 measurement is older, recorded on 2025‑01‑13 23:00 UTC, indicating a gap of more than a year for this specific metric.

Because each pollutant appears in only one row, the reported minimum, median and maximum values are identical, so no spread or variability can be derived from the current dataset. The uniformity across most timestamps suggests that the station is actively reporting recent conditions, yet the outdated PM10 entry highlights an uneven coverage among pollutants. With just a single monitoring location, the figures reflect conditions at that point in Riyadh and may not capture spatial differences across the wider governorate.

Data notes

The data shown are based on five valid measurements and were updated within three days, with the most recent reading recorded at 2026‑02‑10 22:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and fluctuate throughout the day, so values may not represent the entire Riyadh governorate at all times.
