Air quality today

The air quality in Red Deer today is rated as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 5.0 µg/m³, based on three valid observations recorded by OpenAQ.

Overall conditions meet the Good category criteria with no additional pollutants reported. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Red Deer’s open‑air quality feed includes measurements for ozone (O₃), fine particulate matter (PM₂.5), coarse particles (PM₁₀), ultrafine particles (PM₁), relative humidity, temperature and particle count (UM003). The dataset is built from nine individual rows that come from three monitoring locations in the city. For two of the pollutants – PM₂.5 and O₃ – the most recent reading was recorded on 2026‑02‑10 at 22:00 UTC, and both are flagged as having been updated within the last three days. The median PM₂.5 concentration across those rows is 5.0 µg/m³, with values ranging from a low of 4.3 µg/m³ to a high of 47.33 µg/m³; the 10th‑percentile sits at about 4.44 µg/m³ and the 90th‑percentile near 38.86 µg/m³, showing a fairly wide spread around the typical level. Ozone is reported as a single constant value of 0.035 ppm for the same timestamp.

In contrast, the remaining five variables – PM₁, PM₁₀, relative humidity, temperature and UM003 – have no recent timestamps; their “last updated” fields are blank and are marked as “Update unknown.” Each of these shows only one recorded value: PM₁ at 27.58 µg/m³, PM₁₀ at 59.02 µg/m³, relative humidity at 69 %, temperature at 16.47 °C and particle count at 6 024.66 particles/cm³. Because the data for these metrics is not time‑stamped, it cannot be confirmed how current they are, which limits confidence in describing present‑day conditions for those aspects.

Overall, Red Deer’s air‑quality snapshot provides fresh, multi‑day coverage for PM₂.5 and ozone from three stations, while the other measured parameters lack recent timestamps and therefore offer only a static view. Users should keep in mind that actual conditions can differ across neighbourhoods and over time, especially for the variables with unknown update dates.

Data notes

The current dataset for Red Deer includes three valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC, meaning it is updated within three days. These values represent a snapshot of ambient conditions across the city; however, air quality can differ by specific location and time of day, so individual experiences may vary from the reported figures.
