Air quality today

The air quality in Edmonton today is classified as Good. The primary pollutant measured is PM2.5 (fine particles).

A recent set of 32 valid measurements shows a PM2.5 concentration of 5.07 µg/m³. No PM10 value is available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Edmonton currently contains data from 68 individual measurements taken at 16 monitoring sites across the city. All of the listed pollutants are represented: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter of three size fractions (PM1, PM2.5 and PM10), relative humidity, sulfur dioxide (SO2), temperature and the particle count metric UM003. However, the number of recent records varies widely by pollutant. The freshest entries were recorded on 2026‑02‑10 at 22:00 UTC for most variables, with the exception of PM10 whose latest reading dates back to 2025‑01‑13 at 23:00 UTC. CO and NO2 each have three recent rows, while PM1, PM2.5, relative humidity, temperature, and UM003 each have nine recent rows. In contrast, a substantial portion of the dataset is older or lacks a clear timestamp: 18 rows are marked as old and another 13 are unknown, indicating that city‑wide conditions can differ considerably depending on when and where a sensor last reported.

Across the recent data, pollutant concentrations show a broad spread. For PM2.5 the median value is about 9.6 µg/m³ with values ranging from near zero up to 65 µg/m³; the 10th‑percentile sits at 0.1 µg/m³ while the 90th‑percentile reaches roughly 38 µg/m³, highlighting occasional high spikes. PM1 follows a similar pattern but stays lower overall, with a median of 5.48 µg/m³ and a maximum of about 35 µg/m³. Temperature readings span from –7.9 °C to 25.0 °C, centering around a median of 10.9 °C, while relative humidity varies between roughly 23 % and 46 %, medianing near 33 %. CO concentrations are low, ranging from 0.1 to 0.8 ppm with a median of 0.4 ppm, and NO2 stays under 0.022 ppm, medianing at 0.01 ppm.

Because many stations report older or missing timestamps, the dataset does not provide uniform real‑time coverage for every pollutant across Edmonton. Users should keep in mind that air quality can change quickly and may differ between neighborhoods, especially where recent sensor data are sparse.

Data notes

The data shown reflects 32 valid measurements and is Updated within 3 days; the latest values were recorded on 2026‑02‑10 at 22:03:50 UTC. This snapshot provides a brief overview of current conditions, but air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured in these figures.
