Air quality today
The air quality in Ventspils is classified as USG today. The primary pollutant identified is PM2.5, and the available data show a PM2.5 reference value of 39.0 µg/m³ alongside a PM10 reference value of 42.0 µg/m³, based on two valid measurements.
These figures reflect the current conditions as reported by OpenAQ for Ventspils. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Ventspils air‑quality dataset contains five measured pollutants – nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). Data come from two monitoring stations, giving a total of two rows in the source table. The older three records are flagged as “Old data” and date back to 2022‑01‑03 09:00 UTC, while the most recent measurements for PM10 and PM2.5 were updated on 2026‑02‑10 18:00 UTC, showing that the freshest information is only available for the particulate fractions.
Across all pollutants the reported values are single points rather than ranges: NO2 is recorded at 28.4 µg/m³, O3 at 32.59 µg/m³ and SO2 at 2.33 µg/m³, each from the LV0007A station with a last‑updated timestamp of 2022‑01‑03 09:00 UTC. The particulate measurements come from the Ventspils parventa site, both showing identical timestamps of 2026‑02‑10 18:00 UTC and values of 42.0 µg/m³ for PM10 and 39.0 µg/m³ for PM2.5.
Because only two stations contribute data, coverage is limited and uneven: the gaseous pollutants are represented solely by older records, whereas the particulate matter data are relatively recent. The dataset contains no entries with unknown or missing timestamps, but three of the five pollutant rows are more than four years old, indicating that conditions for NO2, O3 and SO2 may not reflect current levels. Consequently, while Ventspils has up‑to‑date information on particulate concentrations, its snapshot of gaseous pollutants is dated, and city‑wide air quality can differ across locations and times beyond what these two rows capture.

Data notes
The data shown for Ventspils is based on two valid measurements and was refreshed recently, Updated within 3 days (last update: 2026‑02‑10T18:00:00+00:00). These values provide a snapshot of current conditions but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this brief overview.
