Air quality today

The air quality in Miskolc is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 28.0 and a PM10 reference value of 30.0, based on seven valid observations.

Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Miskolc’s OpenAQ feed currently provides data for six pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). The dataset contains 21 individual measurement rows collected from four monitoring stations across the city, giving a modest spatial coverage that may not capture all local variations.

Overall data freshness is mixed: six rows are older than thirty days or have an unknown timestamp, eight rows are classified as “old” (more than seven days old), one row was updated within the last week, and six rows were refreshed in the past three days. The most recent observations for each pollutant show that CO, NO₂ and SO₂ are based on older records (last updates on 2025‑05‑08 23:00 UTC, 2025‑08‑15 06:00 UTC and 2026‑02‑06 09:00 UTC respectively), while PM10, PM2.5, O₃ and the newest PM10 reading were updated on 2026‑02‑10 20:00 UTC.

Across the pollutants, measured values span a wide range. CO concentrations vary from 415 µg/m³ to 766 µg/m³ with a median of about 426 µg/m³, indicating relatively high carbon monoxide levels at the sampled sites. NO₂ ranges from 1.9 µg/m³ up to 30.8 µg/m³ (median ≈ 6 µg/m³), while SO₂ shows values between 1.8 µg/m³ and 25.8 µg/m³ (median ≈ 4.9 µg/m³). Particulate matter is less variable: PM10 sits between 12.2 µg/m³ and 30 µg/m³ (median 16.5 µg/m³) and PM2.5 from 13 µg/m³ to 28 µg/m³ (median 13 µg/m³). Ozone measurements are tightly clustered, ranging only from 29.4 µg/m³ to 46.9 µg/m³ with a median of 46.5 µg/m³.

These figures illustrate that while the dataset includes all six key pollutants, the temporal coverage is uneven and many records are dated, so conditions can differ noticeably across neighborhoods and over time.

Data notes

The data shown for Miskolc is based on seven valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T20:00:00+00:00. While these figures give a reliable snapshot of current conditions, air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in this summary.
