Air quality today

The air quality in Belgrade is classified as Good today. The primary pollutant identified is PM2.5, fine particulate matter measured by OpenAQ.

A single valid measurement recorded a PM2.5 concentration of 7.7 µg/m³. No PM10 value is available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ dataset for Belgrade contains measurements from 20 monitoring rows covering ten different pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of three size fractions (PM1, PM2.5, PM10), sulfur dioxide (SO₂), relative humidity and temperature. The overall record includes 107 recent‑type entries, but the majority are older than seven days; only one pollutant – PM2.5 – has a measurement that was updated on 2026-02-10 at 21:58 UTC, while all other parameters were last refreshed on 2025-12-29 (or earlier for PM1 and relative humidity on 2024-11-09). This means the freshest snapshot of Belgrade’s air quality is a PM2.5 value of 7.7 µg/m³ recorded at the International School of Belgrade, whereas the oldest single‑station reading dates back to November 2024.

Across the available data the observed ranges are wide. For particulate matter, PM10 values span from about 28.8 µg/m³ up to 155.2 µg/m³ with a median near 58.5 µg/m³, while PM2.5 varies between 7.7 and 149.0 µg/m³ (median roughly 53.7 µg/m³). Gaseous pollutants also show considerable spread: CO ranges from 429.8 to 1 975.4 µg/m³ (median about 899 µg/m³), NO₂ from 17.3 to 66.5 µg/m³ (median 42.1 µg/m³), SO₂ from 5.2 to 14.9 µg/m³ (median 8.8 µg/m³) and O₃ from 1.5 to 60.4 µg/m³ (median 7.9 µg/m³). The single PM1 reading sits at 60.0 µg/m³, and relative humidity is recorded as a constant 66.4 % for the same station.

Because most rows are dated more than six months old, the dataset provides only a limited view of current conditions; spatial variability can be significant across Belgrade, and the age of many measurements should be taken into account when interpreting these figures.

Data notes

The data shown for Belgrade is based on a single valid measurement and was updated within 3 days, with the latest reading recorded at 2026‑02‑10T21:58:59+00:00. This snapshot reflects conditions at that specific time and location; air quality can differ across neighborhoods and change rapidly throughout the day. Use this information as a general reference rather than a precise real‑time forecast.
