Air quality today

The air quality in Kostrena is classified as Good today. The primary pollutant measured is PM2.5, fine particulate matter that is monitored by OpenAQ.

Measurements show a PM2.5 concentration of 8.50 µg/m³ based on five valid readings collected for the city. No PM10 value is available at this time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Kostrena contains six recorded parameters from a single monitoring location: PM1 at 6.36 µg/m³, PM2.5 at 8.50 µg/m³, PM10 at 10.51 µg/m³, relative humidity at 61.85 %, temperature at 13.22 °C and particle count (UM003) at 1 374 particles/cm³. All values except PM10 were last refreshed on 2026‑02‑10 22:00 UTC, meaning the newest measurements are less than three days old. The PM10 reading is older, dated 2025‑01‑13 23:00 UTC, so that particular pollutant reflects conditions from more than a year ago.

Because only one station contributes data, the coverage across pollutants is uneven: five of the six parameters have current observations, while PM10 relies on an outdated entry. The narrow range for each measured variable—each showing identical minimum, median and maximum values—indicates that only a single observation per pollutant is available at this time. Consequently, the dataset cannot reveal variability or trends within Kostrena; it provides a snapshot rather than a continuous record.

Overall, the data set offers a concise but limited picture of air quality in Kostrena. Fresh readings are present for most pollutants, yet the reliance on a single site and the stale PM10 value mean that conditions may differ across neighborhoods or change throughout the day without being captured here.
