Air quality today

The air quality in Hengelo today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 23.10 µg/m³, based on five valid observations recorded by OpenAQ.

Overall conditions reflect the moderate category with fine particulate matter being the dominant factor. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Hengelo air‑quality dataset draws from a single monitoring site – the Nijverheid station – and contains six recorded variables. For particulate matter the data include PM1 at 14.75 µg/m³, PM2.5 at 23.10 µg/m³ and PM10 at 52.19 µg/m³. In addition to particles, the set provides the latest relative humidity (69.46 %), temperature (10.88 °C) and a count of ultrafine particles (UM003) measured as 2 289.23 particles per cm³.

All six rows are present, but their timestamps differ in recency. The most recent updates for PM1, PM2.5, relative humidity, temperature and UM003 were recorded on 2026‑02‑10 at 22:00 UTC, meaning these values are less than a week old. By contrast the PM10 reading is older, last updated on 2025‑01‑13 at 23:00 UTC, so it reflects conditions from more than a year ago. This mix of fresh and dated entries shows that while most pollutants have current measurements, the coarse dust data (PM10) are not being refreshed as regularly.

The dataset’s narrow coverage – one station providing a single value for each pollutant – limits its ability to capture spatial variation across Hengelo. Nevertheless, the available numbers give a snapshot of the city’s air at the time of measurement: particle concentrations cluster around a single point (no spread in min‑max values), humidity sits just under 70 %, and temperature is close to 11 °C. Users should keep in mind that conditions can differ elsewhere in the municipality and that the older PM10 figure may not represent today’s environment.

Data notes

The data shown for Hengelo reflects five valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of citywide air quality, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
