Air quality today

The air quality in Hamburg today is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 25.36 µg/m³. In addition, the level of PM10 recorded is 28.2 µg/m³.

A total of 65 valid measurements contribute to this assessment. 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

The Hamburg air‑quality dataset contains recent measurements for eight pollutants – carbon monoxide (CO) is not reported in the current rows, but nitrogen oxides (NO and NO₂), ozone (O₃), sulphur dioxide (SO₂), particulate matter of three size fractions (PM1, PM2.5, PM10), and relative humidity are all present. In total 100 individual data rows have been collected from 25 monitoring stations across the city, giving a fairly broad spatial coverage for most of the listed compounds.

The freshest observations were recorded on 2026‑02‑10 between 18:00 and 19:01 UTC, with every pollutant except NO having a last‑updated timestamp within the past three days. The NO data are older, dating back to 2024‑03‑11, which means that for nitrogen monoxide the city’s picture is less current than for the other substances. Median values show a moderate spread: NO₂ sits at 25 µg/m³ (range 12–46 µg/m³), PM2.5 averages 28 µg/m³ (8–50 µg/m³), and PM10 averages 32 µg/m³ (8–58 µg/m³). Ozone’s median is 20 µg/m³ with a narrower range of 13–30 µg/m³, while SO₂ remains low at a constant 2.5 µg/m³ across all rows.

Coverage is uneven: the dataset includes 17 recent NO₂ readings, 16 for PM2.5, 15 for PM10, but only six rows each for PM1, O₃ and relative humidity, and just twelve for NO. Consequently, while most pollutants have a solid set of recent values, some – notably NO and the finer particulate fractions – are represented by fewer stations or older records. Users should keep in mind that conditions can differ between neighborhoods and over time, especially where data are sparse or not up‑to‑date.

Data notes

The data shown for Hamburg are based on 65 valid measurements and were refreshed recently, Updated within 3 days; the latest update was recorded at 2026‑02‑10T19:01:28+00:00. This snapshot reflects conditions at the time of collection but air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
