Air quality today
The air quality in Estevan today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 3.0 µg/m³ based on three valid readings collected via OpenAQ. This indicates that the fine particle level aligns with the reference value provided for this pollutant. 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 Estevan includes three measured pollutants—nitrogen dioxide (NO2), ozone (O3) and fine particulate matter (PM2.5). All values come from a single monitoring location, giving a total of three recent rows in the OpenAQ feed. Each pollutant has only one recorded value, so the minimum, median and maximum are identical: NO2 is 0.005 ppm, O3 is 0.029 ppm and PM2.5 is 3.0 µg/m³. Because there is just a single observation per contaminant, there is no spread to describe; the data represent a snapshot rather than a distribution.
The latest update for every pollutant was recorded on 2026-02-10 at 22:00 UTC, and each entry carries a “Updated within 3 days” flag, indicating that the information is fresh as of the current reporting period. No older or unknown‑age rows are present in this city’s feed, so the coverage is limited but timely. Because only one monitoring site contributes data, spatial variation across Estevan cannot be captured; conditions may differ in other neighbourhoods or at different times of day.
In practical terms, users can rely on these three current readings for a very recent picture of air quality at that specific point, but should keep in mind the lack of multiple stations or repeated measurements. The dataset’s completeness is constrained to a single location and one value per pollutant, so broader trends or localized differences are not reflected here.

Data notes
The current dataset for Estevan includes three valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:00:00+00:00. These values represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so this information may not reflect the exact situation at any specific location or moment.
