Air quality today
The air quality in Lappeenranta today is classified as Moderate. The primary pollutant measured is PM2.5, with a reported concentration of 10.0905647 µg/m³. A secondary measurement for larger particles shows PM10 at 12.1986456 µg/m³, based on three valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes
The Lappeenranta air‑quality feed contains three measured pollutants – nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10) and fine particulate matter up to 2.5 µm (PM2.5). Data come from six recent rows recorded at three distinct monitoring sites across the city, with each pollutant reported from two stations. The most recent timestamp for every series is 2026‑02‑10 18:00 UTC, and all entries are marked as updated within the past three days, indicating a uniformly fresh snapshot of conditions.
For NO2 the observed values span from a low of about 9 µg/m³ to a high of 37 µg/m³, with a median near 23 µg/m³. The ten‑percentile sits at roughly 12 µg/m³ and the ninety‑percentile at 34 µg/m³, showing that most readings cluster in the lower half of the range while occasional peaks approach the upper end. PM10 measurements are tightly grouped, ranging only from 11.6 to 12.2 µg/m³; the median is 11.9 µg/m³ and both the tenth and ninetieth percentiles lie within a narrow band (≈11.6–12.1 µg/m³), indicating very little variation across the sites reporting this pollutant. PM2.5 values are broader, from a minimum of 3 µg/m³ to a maximum of 10 µg/m³, with a median of about 6.5 µg/m³; the spread between the tenth (≈3.7 µg/m³) and ninetieth percentiles (≈9.4 µg/m³) reflects moderate variability.
Overall the dataset provides recent, city‑wide coverage for all three pollutants, though the number of stations differs slightly: NO2 and PM10 each have two reporting locations, while PM2.5 is captured at a single site. The narrow range for PM10 suggests consistent conditions across monitored points, whereas NO2 and PM2.5 show more fluctuation, highlighting that air quality can differ by location even within the same short time frame.

Data notes
The data shown for Lappeenranta is based on three valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10 18:00 UTC. While this snapshot reflects current conditions at the monitoring site, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
