Air quality today

The air quality in Jihlava today falls into the Moderate category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 15.0 µg/m³ and a PM10 reference value of 17.0 µg/m³, based on three valid observations.

These figures reflect the current monitoring snapshot for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Jihlava air‑quality feed contains measurements for six pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulphur dioxide (SO₂). The dataset is built from nine rows of observations collected at two monitoring stations, so the spatial coverage within the city is limited to these points.

For three of the pollutants – NO₂, PM10 and PM2.5 – the most recent values were recorded on 2026‑02‑10 at 14:00 UTC, which falls within the “updated within 3 days” freshness category. The reported ranges show that NO₂ varied from a low of 3.4 µg/m³ to a high of 13.0 µg/m³, with a median around 8.2 µg/m³; PM10 values were tightly clustered between 17.0 and 19.0 µg/m³ (median 18.0), while PM2.5 spanned 15.0 to 20.0 µg/m³ (median 17.5). These three pollutants therefore provide a fairly current snapshot of the city’s air quality.

In contrast, CO, O₃ and SO₂ are only represented by data last updated on 2018‑04‑25 at 17:00 UTC, making them over five years old. Each of these older entries shows a single recorded value – CO 135.0 µg/m³, O₃ 107.7 µg/m³ and SO₂ 1.3 µg/m³ – without any recent variation. Because the majority of rows (six out of nine) are classified as “old” or “unknown,” the overall dataset is skewed toward historical information for half of the measured pollutants.

Consequently, while the city’s current NO₂, PM10 and PM2.5 levels can be described with recent ranges and medians, the picture for CO, O₃ and SO₂ relies on outdated single‑point measurements. Users should keep in mind that air quality can differ across neighborhoods and over time, and the limited number of stations means the available data represent only a snapshot rather than a comprehensive citywide view.

Data notes

The data shown for Jihlava are based on three valid measurements and were updated within 3 days, with the latest refresh recorded at 2026‑02‑10 14:00 UTC. These figures represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not reflect current or localized levels elsewhere in the city.
