Air quality today
The air quality in Medicine Hat today is classified as Good. The primary pollutant measured is PM2.5 (fine particles). Recent observations show a PM2.5 concentration of 2.8 µg/m³, based on two valid measurements 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.
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 data for Medicine Hat includes two measured pollutants, ozone (O3) and fine particulate matter (PM2.5), each reported from a single monitoring location identified as “Medicine Hat - Cresc.” In total the dataset contains two rows of observations, both coming from this one station. The most recent update for each pollutant was recorded on 2026-02-10 at 22:00 UTC, meaning the freshest values are just a few days old.
For ozone, every recorded value is identical: 0.041 ppm. The minimum, median, and maximum all match this figure, and the 10th and 90th percentiles are also 0.041 ppm, indicating no observed variation across the available record. PM2.5 shows a similar pattern, with each entry reporting exactly 2.8 µg/m³; again the range is flat, with min, median, max and percentile values all equal to 2.8 µg/m³.
Because both pollutants are represented by a single station and only one timestamp per pollutant, the dataset provides a very narrow snapshot of air quality in Medicine Hat. There is no spread or temporal depth to illustrate how conditions might change across different parts of the city or over longer periods. While the data are recent, the lack of multiple stations or historic rows means that local variations in ozone or fine particles cannot be captured here. Users should keep in mind that these figures reflect a single point in time and space rather than a comprehensive view of the city's air quality.

Data notes
The current dataset for Medicine Hat includes two valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is therefore considered “Updated within 3 days.” This snapshot reflects conditions at the time of collection, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
