The air quality in Naantali today falls into the Good category. The main pollutant identified is PM10, which represents coarser particulate matter measured in the local monitoring network.
Four valid measurements were recorded, and the reference value for PM10 is 1.146837. This figure reflects the concentration level used to assess air quality conditions for the city at this time. 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 dataset for Naantali in Southwest Finland contains measurements from a single monitoring location, “Naantalin keskusta,” and includes two pollutants: nitrogen dioxide (NO₂) and particulate matter ≤ 10 µm (PM₁₀). In total there are four data rows, all tied to this one station, so the spatial coverage is limited to the city centre.
Both pollutants have a single recorded value that also serves as the minimum, median and maximum for the period covered. The NO₂ concentration is 10.5423775 µg/m³, while PM₁₀ measures 1.146837 µg/m³. Because each metric shows no variation (the 10th‑percentile, median and 90th‑percentile are identical), the dataset does not reveal any spread or fluctuations over time.
The most recent observations for both NO₂ and PM₁₀ were logged on 2026-02-10 at 18:00 UTC. This timestamp is within three days of the current date, indicating that the data are fresh. However, with only one monitoring site and a single reading per pollutant, the information provides a very narrow snapshot of air quality in Naantali; conditions elsewhere in the city or changes throughout the day are not captured.
