Air quality today

The air quality in Outreau today is classified as Good. The primary pollutant measured is PM10, with a reported reference value of 7.8 µg/m³ based on two valid observations.

These measurements indicate that particulate matter levels are within the range associated with the Good category. Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Outreau’s OpenAQ feed contains data for five measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or less (PM₁₀). The dataset is built from eight rows of observations that originate from two monitoring stations in the city. Freshness varies considerably across the pollutants: the most recent O₃ reading was logged on 2026‑02‑10 at 15:00 UTC, PM₁₀ on 2026‑02‑08 at 14:00 UTC and NO₂ on 2024‑12‑09 at 12:00 UTC. In contrast, CO data are from 2017‑01‑25 at 01:00 UTC and NO data from 2024‑03‑11 at 09:00 UTC, indicating that those two compounds have not been updated for several years.

The recorded values show a narrow spread for most pollutants. For NO₂ the measurements range from 5.3 to 9.1 µg/m³ with a median of about 7.2 µg/m³; O₃ varies between 69.15 and 73.0 µg/m³, median roughly 71.1 µg/m³; PM₁₀ is between 7.8 and 9.53 µg/m³, median near 8.7 µg/m³. CO is a single constant value of 145.0 µg/m³ across its lone row, and NO likewise shows only one recorded figure of 1.1 µg/m³. This means that for three pollutants (NO₂, O₃, PM₁₀) there are multiple recent observations allowing an assessment of typical levels, while CO and NO rely on outdated single points.

Overall, the dataset provides a modest snapshot of air quality in Outreau: two stations supply recent data for three key gases and particles, but half of the pollutants are represented only by old or singular entries. Consequently, conditions can differ across neighborhoods and times, and the current picture may not capture short‑term fluctuations that occur between measurement updates.
