Air quality today

The air quality in Skopje is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 26.7 and a PM10 reference value of 48.883, based on 19 valid observations collected via OpenAQ.

These figures reflect the present conditions without implying any trend or forecast. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Skopje contains measurements of carbon monoxide (CO), nitrogen oxides (NO and NO₂), ozone (O₃), particulate matter (PM₁₀ and PM₂.₅) and sulphur dioxide (SO₂). In total 33 rows of data are drawn from five monitoring stations, giving a modest spatial coverage across the city. The most recent updates for CO, NO₂, O₃, PM₁₀, PM₂.₅ and SO₂ were recorded on 2026‑02‑10 at 18:00 UTC, which falls within the “updated within 7 days” freshness bucket. Nitrogen monoxide (NO) is the exception; its latest entry dates back to 2024‑03‑11 at 12:00 UTC and is flagged as old data, indicating a gap in recent coverage for that pollutant.

Across the available pollutants the observed values span a wide range. CO concentrations vary from a low of 464 µg/m³ up to a maximum of 8 955 µg/m³, with a median around 498 µg/m³ at the Gazi Baba station. NO₂ shows a much tighter distribution, ranging from 0 to 37 µg/m³ and a median of roughly 27 µg/m³, also measured at Gazi Baba. Ozone values are near zero, fluctuating between –1 and 7.4 µg/m³ with a median of 0 µg/m³. Particulate matter is relatively low: PM₁₀ ranges from 11 to 48.9 µg/m³ (median ≈ 35 µg/m³) and PM₂.₅ from –1 to 26.7 µg/m³ (median ≈ 22 µg/m³), both recorded at Gazi Baba. SO₂, measured at the Lisice station, spans 0.27 to 4.79 µg/m³ with a median of about 3.07 µg/m³.

The data set therefore offers recent information for most pollutants but is uneven in temporal completeness, especially for NO where the latest reading is almost two years old. With only five stations contributing, conditions can differ noticeably between neighbourhoods and over time, so the figures represent a snapshot rather than a comprehensive city‑wide picture.

Data notes

The dataset for Skopje includes 19 valid measurements and is marked as Updated within 3 days, with the most recent data recorded at 2026‑02‑10T18:00:00+00:00. This information reflects a single snapshot of conditions; air quality can differ across neighborhoods and change throughout the day, so values shown may not represent every location or moment in the city.
