Air quality today

The air quality in Wealden today falls into the Good category according to the latest assessment. The primary pollutant identified is PM2.5, with a reference value of 4.0 µg/m³, while the reference level for PM10 stands at 5.0 µg/m³. Measurements from eight valid monitoring points were used to determine this rating.

Data are shown via OpenAQ and reflect the current conditions without speculation or forecast. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Wealden pulls data from nine individual measurement rows collected at three monitoring stations, all supplied through the OpenAQ network. Five key pollutants are represented: nitrogen dioxide (NO₂), ozone (O₃), sulphur dioxide (SO₂), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). Each pollutant has at least one recent observation, with the most current timestamp for every series being 2026‑02‑10 20:00 UTC, which falls within the “updated within seven days” freshness window.

Ozone shows the widest spread among the available data, ranging from a low of 62.1 µg/m³ to a high of 75.0 µg/m³, with a median value of 71.9 µg/m³ and the central 80 % of readings falling between roughly 64 µg/m³ and 74 µg/m³. Nitrogen dioxide is measured at much lower concentrations, varying from 3.1 to 5.0 µg/m³; its median (4.05 µg/m³) sits close to the middle of a narrow band between about 3.3 and 4.8 µg/m³. Sulphur dioxide follows a similar pattern, recorded between 1.4 and 2.0 µg/m³ with a median of 1.7 µg/m³ and an inter‑decile range of roughly 1.5 to 1.9 µg/m³.

The particulate metrics are the most limited in coverage: both PM10 and PM2.5 have only a single recorded value each—5.0 µg/m³ for PM10 and 4.0 µg/m³ for PM2.5—from the same station (Lullington Heath – UKA00152) on the same date and time as the other pollutants. Because there is just one row per particulate type, no distribution can be described beyond that point measurement. Overall, while the dataset is fresh, the depth of information varies: ozone, NO₂ and SO₂ benefit from multiple rows that reveal modest variability, whereas the particulate data are sparse, reflecting limited sampling across the city’s monitoring network.
