How to read it
AQI, PM2.5 and PM10 describe different parts of the air picture
The AQI value is an index intended to summarize current air conditions, while PM2.5 and PM10 are particulate-matter measurements. They should not be treated as interchangeable values or as a permanent rating of Warsaw.
Air conditions can change with weather, season, local activity and measurement timing. Placeivo therefore keeps the observation date and latest check visible and avoids converting a single reading into a broad city health or quality-of-life verdict.
Recent trend
Warsaw air quality over the last 7 days
Daily values below are averages calculated from hourly European AQI, PM2.5 and PM10 observations. This recent window shows short-term variation; it is not a long-term annual air-quality rating.
| Date | European AQI | PM2.5 | PM10 |
|---|---|---|---|
| Sep 9 | 39.6 | 13.4 µg/m³ | 19.8 µg/m³ |
| Sep 10 | 26.3 | 7.0 µg/m³ | 10.2 µg/m³ |
| Sep 11 | 38.0 | 13.6 µg/m³ | 19.6 µg/m³ |
| Sep 12 | 36.5 | 13.9 µg/m³ | 18.6 µg/m³ |
| Sep 13 | 39.5 | 17.3 µg/m³ | 24.6 µg/m³ |
| Sep 14 | 40.8 | 18.3 µg/m³ | 23.2 µg/m³ |
| Sep 15 | 42.0 | 18.5 µg/m³ | 25.6 µg/m³ |

Evidence interpretation
What the latest Warsaw air readings say
The latest stored measurements report a European AQI of 42, PM2.5 of 18.1 µg/m³ and PM10 of 21.6 µg/m³.
These are time-specific environmental measurements. They are useful as a current snapshot, but a single reading cannot establish typical annual air quality or a permanent health ranking for Warsaw.
Evidence & methodology
Where these air quality figures come from
Placeivo keeps source attribution, the date represented by the observation, the latest verification check and confidence metadata separate. This makes it possible to inspect the evidence instead of relying on an unexplained score.
