Air quality today

The air quality today in Düsseldorf is classified as Good. The primary pollutant identified for the current assessment is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 2.20 µg/m³ and a PM10 level of 8.24 µg/m³, based on twenty valid observations recorded by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Düsseldorf currently contains data from five monitoring sites spread across the city, providing a total of twenty‑four individual readings. All nine pollutants measured by the network are represented: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 1 µm (PM1), PM2.5, PM10, sulphur dioxide (SO₂), relative humidity and temperature (recorded as UM003). The most recent values were all logged on 2026‑02‑10, with timestamps ranging from 18:00 to 19:00 UTC for the majority of pollutants; the only older entry is NO, last updated on 2024‑03‑11 at 11:00 UTC. This means that except for NO, every pollutant has a measurement that is less than three days old, giving a fairly fresh snapshot of current air quality.

Across the dataset the concentration ranges vary considerably. PM2.5 values span from just over 2 µg/m³ up to about 6.5 µg/m³, with a median near 4.7 µg/m³, indicating relatively low but measurable fine‑particle levels at the sampled sites. NO₂ shows a tighter band, ranging between 24 and 36 µg/m³ and clustering around a median of 35 µg/m³, while ozone is confined to a narrow window of 15–20 µg/m³ with a median close to 18 µg/m³. In contrast, the particulate matter larger than 10 µm (PM10) exhibits a modest spread from roughly 6 to 11 µg/m³, centered on a median of about 8 µg/m³. The single‑point measurements for SO₂, PM1 and relative humidity are all identical to their respective minima, medians and maxima because each was recorded at only one site.

The dataset is unevenly populated: NO has four separate rows but the newest reading is more than a year old, whereas pollutants such as O₃, NO₂, PM10 and PM2.5 each have four recent entries. Because the coverage differs by pollutant and some stations contribute only a single observation, conditions can differ noticeably between neighbourhoods and over short time spans. Users should keep in mind that the figures reflect specific moments at particular locations rather than a continuous city‑wide average.

Data notes

The data shown are based on 20 valid measurements and have been updated within 3 days, with the latest refresh recorded at 2026‑02‑10T19:00:00+00:00. This snapshot reflects conditions across Düsseldorf at a single point in time; air quality can differ by neighbourhood and change throughout the day, so values may not represent every location or moment within the city.
