Air quality today
The air quality in Reigate and Banstead is currently classified as Good. The main pollutant measured today is PM2.5 (fine particles). Data from three valid measurements show a PM2.5 reference value of 5.0 µg/m³ and a PM10 reference value of 7.0 µg/m³, indicating that fine particle concentrations are within the limits associated with this category.
These figures are derived from OpenAQ data sources and reflect the latest available readings for the area. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes
The air‑quality data for Reigate and Banstead currently comes from three monitoring rows, all of which are recent enough to be considered up‑to‑date: the latest readings were recorded on 2026‑02‑10 at 20:00 UTC and each pollutant’s freshness is described as “Updated within 7 days”. The dataset includes measurements for nitrogen dioxide (NO2), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Because only one monitoring site – Horley (UKA00511) – supplies data for each pollutant, the spatial coverage is limited to that single location within the borough.
For NO2 the observed values range from a minimum of 12.6 µg/m³ to a maximum of 16.0 µg/m³, with a median of 12.9 µg/m³ and the central 80 % of readings falling between roughly 12.7 and 15.4 µg/m³. PM10 shows a single reported value of 7.0 µg/m³, which is both the minimum and maximum, while PM2.5 also reports only one value at 5.0 µg/m³. This means that for the particulate pollutants there is no observed spread in the data; the measurements are identical across all rows that exist.
Overall, the dataset contains three recent rows out of a possible five, with two older entries classified as “old” and none marked as unknown or missing. While the NO2 readings give a modest range to describe variability at the Horley site, the particulate matter figures lack any variation because only one observation is available for each. Consequently, the picture of air quality in Reigate and Banstead is based on a very small number of recent measurements from a single monitoring point, and conditions elsewhere in the borough may differ from those captured here.
