Air quality today

The air quality in Dunkirk today is classified as Good. The primary pollutant measured is PM2.5, with a reference concentration of 4.8 µg/m³, while the corresponding PM10 value stands at 6.9 µg/m³ based on nine valid observations.

Data are shown via OpenAQ and reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Dunkirk currently provides data on seven pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulphur dioxide (SO₂). These measurements come from six monitoring stations that together generate 21 recent rows of data. The most up‑to‑date observations are all within the last three days for five of the pollutants, while CO and NO rely on older records: the newest CO value dates back to 2017‑01‑24 12:00 UTC and the latest NO reading is from 2024‑03‑11 09:00 UTC. The freshest timestamps for the other gases are all from 2026‑02‑10, with O₃, PM2.5, PM10 and NO₂ recorded at 15:00 UTC and SO₂ at 03:00 UTC on 2026‑02‑09.

Across the dataset the concentration ranges vary considerably. For PM10 the values span from a low of 3.2 µg/m³ to a high of 29.9 µg/m³, with a median of 6.9 µg/m³; the 10th and 90th percentiles sit at 4.4 µg/m³ and 22.2 µg/m³ respectively, indicating occasional spikes above typical levels. SO₂ shows a much tighter spread, ranging from 0.0 to 6.7 µg/m³ with a median of 0.4 µg/m³, while NO₂ values are clustered between 6.5 and 21.63 µg/m³ (median 21.4 µg/m³). O₃ exhibits the highest absolute readings, from 49.65 up to 73.2 µg/m³, with a median of 61.425 µg/m³, reflecting strong diurnal variation.

The coverage is uneven: PM10 and PM2.5 have five recent rows each, SO₂ also has five, but NO and CO are represented by only two and one rows respectively, both flagged as old data. Consequently, while the city’s particulate and ozone measurements give a fairly current picture, the gas‑phase pollutants rely on dated observations, meaning that real‑time conditions for CO and NO may differ from what is shown here. Users should keep in mind that air quality can change across neighborhoods and over short periods, especially when recent data are limited.

Data notes

The data shown for Dunkirk reflects nine valid measurements and is refreshed — updated within three days, with the latest update recorded at 2026‑02‑10T15:00:00+00:00. This snapshot provides a current view of citywide air quality but conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Dunkirk.
