Air quality today

The air quality in Warwick today falls into the Moderate category according to the latest Duck score assessment. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 10.0 and a PM10 reference value of 12.0, based on seven valid observations collected via OpenAQ.

These figures provide a snapshot of current atmospheric conditions in the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Warwick air‑quality record draws on data from two monitoring stations, giving a total of seven recent observations across the four measured pollutants. All of the latest readings were recorded at the same moment – 2026‑02‑10 20:00 UTC – so the dataset reflects conditions captured at that single point in time rather than an ongoing stream.

Four key gases and particles are represented. Nitrogen dioxide (NO₂) shows a modest spread, with values ranging from 15 µg/m³ up to 22 µg/m³ and a median of 18.5 µg/m³; the highest observed concentration comes from the Leamington Spa Rugby Road sensor (UKA00564). Particulate matter ≤10 µm (PM₁₀) is reported as a uniform 12 µg/m³, again from the same Rugby Road site, while finer particles (PM₂.₅) are consistently measured at 10 µg/m³ at that location. Ozone (O₃) appears only once in the set, recorded at 51 µg/m³ by a Leamington Spa monitor.

Because the data set contains just two stations, coverage across Warwick is limited and does not capture spatial variation within the city. The uniformity of the PM₁₀ and PM₂.₅ figures suggests either very stable concentrations at the sampling point or that only a single measurement was available for those pollutants. In contrast, NO₂ exhibits a broader range despite being drawn from the same site, indicating some short‑term fluctuation at the time of capture. Overall, while the timestamps are fresh, the snapshot nature and sparse station network mean that conditions elsewhere in Warwick may differ from what is shown here.

Data notes

The dataset for Warwick includes seven valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T20:00:00+00:00. These figures represent a brief snapshot of ambient conditions; air quality can differ across neighbourhoods and change throughout the day, so individual experiences may vary from the reported values.
