Air quality today
The air quality in Surrey, British Columbia is currently classified as Good. The primary pollutant identified is PM2.5, with recent readings showing a concentration of 1.5 µg/m³. A total of five valid measurements were used to determine this assessment. No PM10 value was provided.
These values reflect the data available through OpenAQ for today. All data are displayed through the OpenAQ platform. Five valid samples support the Good rating. The latest reading was recorded at 2026-02-12 10:00 UTC. PM2.5 concentration of 1.5 µg/m³ is within typical background levels for the region. Measurements are based on ground‑based sensors. 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
Surrey’s air‑quality feed includes five measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM₂.5). The dataset is drawn from a single monitoring location, Surrey East, which contributes five rows of data, one for each pollutant. All of the observations were recorded at the same moment, 2026‑02‑10 22:00 UTC, and are flagged as having been updated within three days, so the information reflects very recent conditions for that site.
The values themselves show no variation across the five rows: CO is reported at 0.1 ppm, NO at 0.0008 ppm, NO₂ at 0.0023 ppm, O₃ at 0.033 ppm and PM₂.5 at 1.5 µg/m³. For each pollutant the minimum, median, maximum, as well as the 10th‑percentile and 90th‑percentile figures are identical, indicating that only a single measurement is available rather than a distribution over time or space. Because the data come from one station, coverage across Surrey is limited; conditions elsewhere in the city may differ from those captured at Surrey East.
In summary, the dataset provides recent, point‑in‑time readings for five key pollutants but does so from just one location and with only one record per pollutant. The lack of multiple stations or repeated measurements means that while the numbers are current, they do not convey variability across neighbourhoods or over longer periods. Users should keep in mind that air quality can change throughout the city and that this snapshot represents a narrow slice of Surrey’s overall atmospheric conditions.
