Air quality today

The air quality in Varese today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 25.9 µg/m³ and a PM10 level of 29.8 µg/m³, based on six valid observations recorded by OpenAQ.

These values 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 Varese air‑quality record contains 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). These measurements come from seven individual rows of sensor readings that are grouped into two monitoring stations in the city.

All of the latest values were uploaded within the past week, so the dataset reflects conditions as recent as 2026‑02‑08 19:00 UTC for PM10 and PM2.5 and 2026‑02‑07 20:00 UTC for the other gases. The freshest timestamps are therefore no older than one day from today’s date, indicating a generally up‑to‑date picture of the local atmosphere.

Across the seven rows the observed concentrations show modest variability. NO₂ ranged from about 39 µg/m³ to 48 µg/m³ with a median near 44 µg/m³, while CO was recorded at a single value of roughly 1 167 µg/m³. Particulate matter displayed consistent levels: PM10 and PM2.5 each appeared in only one row, reporting 29.8 µg/m³ and 25.9 µg/m³ respectively. Ozone and sulfur dioxide were also captured once each, at 10.1 µg/m³ and 3.23 µg/m³. Because many pollutants are represented by a single measurement, the dataset provides limited insight into short‑term fluctuations but does give a clear snapshot of current concentrations.

Overall, Varese’s air‑quality data set is relatively small, with only two stations contributing seven rows, yet it offers recent readings for all six key pollutants. The narrow spread in most values and the presence of single‑row entries mean that while the information is fresh, it may not capture spatial differences across the city or rapid changes over time.

Data notes

The data shown for Varese reflects six valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑08 at 19:00 UTC. This snapshot provides a current view of city‑wide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
