Air quality today
The air quality in Jelgava today falls into the Unhealthy category according to the latest assessment. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 71.68 µg/m³ based on four valid observations, and no PM10 value is available.
Data are shown via OpenAQ and reflect the current monitoring results for the city. 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 Jelgava currently contains five individual measurement rows, each reporting a full set of five pollutants: PM1, PM2.5, relative humidity, temperature and the particle count UM003. All five rows have been updated within the last seven days, with the most recent timestamp recorded at 2026-02-10 19:00 UTC for every parameter. Because each row includes the same suite of variables, coverage is uniform across pollutants – there are no gaps where a particular substance is missing from any recent observation.
Across the five recent entries the values show very little variation, indicating that the sensor readings have been stable over the short reporting window. PM1 consistently registers at 43.353 µg/m³, while PM2.5 remains fixed at 71.684 µg/m³; both figures are identical for the minimum, median and maximum in this period. Relative humidity is recorded at 42.138 % and temperature hovers just below zero at –0.738 °C, again with no spread between the 10th and 90th percentiles. The UM003 particle concentration stays steady at 1 968.259 particles per cubic centimetre throughout all five rows.
The tight clustering of numbers means that the dataset does not capture a range of conditions for Jelgava; any fluctuations in air quality, humidity or temperature that occur outside this narrow window would not be reflected here. While the data are fresh – all entries dated within the past week – the lack of variability suggests limited insight into day‑to‑day changes. Users should keep in mind that actual city conditions can differ by location and time, and the current snapshot provides only a single point of reference for each pollutant.
