Air quality today

The air quality in Bremerhaven today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 19.14 µg/m³ and a PM10 level of 19.27 µg/m³, based on five valid observations reported through 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 Bremerhaven contains data on carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter PM1, PM2.5 and PM10, sulfur dioxide (SO2) as well as relative humidity, temperature and a miscellaneous UM003 variable. In total 16 measurement rows are reported from three monitoring sites across the city.

Most of the pollutants have very recent values: CO, O3, SO2, NO2, PM2.5 and PM10 were all last updated on 2026‑02‑10 18:00 UTC, giving a snapshot that is only a few days old. The newest NO reading, however, dates back to 2024‑03‑11 11:00 UTC, and the sole PM1 record is from 2025‑11‑03 07:00 UTC, so coverage for these two compounds is noticeably older. Across the recent data set, median concentrations are modest – for example the median PM10 level is 19.27 µg/m³ (range 12.4 to 47.43 µg/m³) and the median NO2 is 43.05 µg/m³ (range 15.22 to 70.87 µg/m³). CO shows a single constant value of 390 µg/m³ at the Hansastraße site, while O3 is recorded at a steady 25.77 µg/m³.

The spread between the 10th and 90th percentiles highlights variability: PM10’s 10th percentile is 13.77 µg/m³ versus a 90th percentile of 41.80 µg/m³, and NO’s 10th to 90th range runs from 4.82 to 27.03 µg/m³. Because some pollutants rely on older or single‑point measurements, the dataset does not capture short‑term fluctuations uniformly across all compounds. Consequently, while recent readings give a useful picture of current air quality at the most frequently updated sites, conditions can still differ by location and time within Bremerhaven.
