Air quality today

The air quality in Nieuwegein today is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 19.54 µg/m³ based on five valid observations reported through OpenAQ.

Data for this assessment come from a limited set of recent measurements and reflect the current state without projection. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

Latest sensor values

PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).

What the data includes

The dataset for Nieuwegein contains six measured variables – PM1, PM10, PM2.5, relative humidity, temperature and UM003 (particle concentration) – all recorded at a single monitoring location in the Zuilenstein neighbourhood. Because there is only one row of data, the station coverage is limited to this point rather than representing the whole city.

The most recent readings are from 2026‑02‑10 22:00 UTC for PM1 (7.86 µg/m³), PM2.5 (19.54 µg/m³), relative humidity (66.68 %), temperature (12.46 °C) and UM003 (687.85 particles/cm³). The PM10 value is older, last updated on 2025‑01‑13 23:00 UTC with a concentration of 65.79 µg/m³. This means that five of the six pollutants have fresh data within the past week, while one pollutant relies on information that is more than a year old.

All reported values are single observations, so each metric shows no internal range – the minimum, median and maximum are identical for every parameter. The PM1 concentration sits at 7.86 µg/m³, PM10 at 65.79 µg/m³ and PM2.5 at 19.54 µg/m³, indicating a clear difference between coarse and fine particle levels at this site. Relative humidity is recorded at 66.68 % and temperature at 12.46 °C, providing a snapshot of the ambient conditions accompanying the particulate measurements. The UM003 count of 687.85 particles per cubic centimetre adds an additional view of airborne particle density.

Because the data come from only one location and include an older PM10 entry, they capture a very specific moment in Zuilenstein rather than city‑wide trends. Conditions elsewhere in Nieuwegein may differ, especially where no sensor is present or where measurements are not as recent.

Data notes

The current dataset for Nieuwegein includes five valid measurements and is Updated within 3 days, with the latest values recorded on 2026‑02‑10 at 22:00 UTC. These figures represent a snapshot of air quality across the city; conditions can differ by neighbourhood and change throughout the day, so individual experiences may vary from the reported averages.
