Air quality today
The air quality today in Umeå is classified as Good. The main pollutant identified is PM10, and the reference value for this particle size is 10.8 micrograms per cubic metre. Measurements from two monitoring stations were used to determine the assessment.
Overall conditions meet the criteria for a Good rating based on the available data. 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 Umeå contains measurements for four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). All values come from a single monitoring location, “Umeå Västra Esplanaden”, so the city’s air‑quality picture is based on one station row per pollutant, giving a total of four rows in the current feed.
The most recent observations are mixed in terms of freshness. NO₂ and PM₁₀ were last updated on 2026-02-10 at 17:00 UTC and 18:00 UTC respectively, which falls within the “updated within 7 days” category, indicating very current data for those two gases. In contrast, the NO reading dates back to 2024-03-11 12:00 UTC and the PM₂.₅ measurement to 2024-10-14 07:00 UTC, both classified as “old data”. This uneven timing means that while some pollutants reflect present‑day conditions, others may not capture recent changes in emissions or weather.
Each pollutant shows a single recorded value, so the minimum, median and maximum are identical. NO registers 6.353 µg/m³, NO₂ stands at 59.1 µg/m³, PM₁₀ is measured at 10.8 µg/m³ and PM₂.5 at 14.134 µg/m³. Because there is no spread of values over time or across multiple sites, the dataset cannot illustrate variability within Umeå; it simply provides a snapshot for each pollutant at the listed timestamps. Consequently, while the data give a clear point‑in‑time picture for the monitored location, broader city‑wide conditions may differ depending on where and when measurements are taken.

Data notes
The data shown reflects two valid measurements and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T18:00:00+00:00. These values provide a snapshot of current conditions but air quality can vary across different neighbourhoods and times of day within Umeå, so local levels may differ from those presented here.
