Air quality today
The air quality in Wrexham today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 11.0 and a PM10 reference value of 13.0, based on four valid observations recorded through OpenAQ.
These figures reflect the current monitoring snapshot for the city. 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 Wrexham comes from a single monitoring site (Wrexham - UKA00440) that records four key pollutants: nitrogen dioxide, particulate matter ≤ 10 µm, particulate matter ≤ 2.5 µm and sulphur dioxide. All four measurements were last updated on 2026‑02‑10 at 20:00 UTC, which falls within the “updated within 7 days” freshness category, so the figures reflect very recent conditions.
Because there is only one row of data, each pollutant has a single reported value rather than a range. The observed concentrations are identical across their minimum, median and maximum statistics: NO₂ = 24.0 µg/m³, PM10 = 13.0 µg/m³, PM2.5 = 11.0 µg/m³ and SO₂ = 2.0 µg/m³. This uniformity means the dataset does not capture variability across different parts of the city or over time; it provides a snapshot rather than a distribution.
With just one monitoring location, coverage is limited to the conditions measured at that specific point. While the data are fresh, the lack of multiple stations means spatial differences in air quality cannot be assessed from this source alone. Users should keep in mind that actual pollutant levels may differ elsewhere in Wrexham or change throughout the day, even though the current dataset offers a timely snapshot for the monitored site.
