Air quality today
The air quality in Stockport today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 0.2138 µg/m³ based on five valid observations recorded via OpenAQ. This indicates that the current level of fine particulate matter falls within the range associated with the Good category.

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 dataset for Stockport pulls information from a single monitoring site at Romiley and contains five separate measurement rows. Each row records one of the pollutants tracked by OpenAQ: PM1, PM2.5, relative humidity, temperature and UM003 (particle count). All values are drawn from the most recent upload on 2026‑02‑10 at 21:00 UTC, which falls within the “updated within 7 days” freshness bucket, so the data reflect conditions that were measured just a few days ago.
Across the five rows the recorded concentrations show very little variation because each pollutant has only one reported value. PM1 is consistently zero micrograms per cubic metre, while PM2.5 registers a single reading of 0.21383333380023636 µg/m³. Relative humidity is fixed at 62.64100004831949 %, temperature at 11.892833232879639 °C and the particle counter UM003 reads 144.39166666666668 particles per cubic centimetre. Because there is only one station, the dataset does not capture spatial differences within Stockport; any local fluctuations away from Romiley are not represented.
The narrow coverage—one site providing five pollutant measurements—means that while the timestamps are recent, the picture of air quality in the wider city area remains limited. Users should keep in mind that conditions can differ across neighborhoods and over time, and the current figures give only a snapshot from a single location on a specific date.
