Air quality today

The air quality in South Gloucestershire today falls into the Moderate category. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 14.53 µg/m³ based on five valid observations recorded via OpenAQ.

Data indicate that fine particulate matter remains the dominant factor influencing air quality at this time. No additional pollutants have been highlighted in the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

South Gloucestershire’s OpenAQ feed currently contains data from six monitoring rows covering a single site – Warmley Common – and provides readings for six pollutants: PM1, PM10, PM2.5, relative humidity, temperature and particle count (UM003). The dataset is very compact; each pollutant has only one recorded value because the minimum, median and maximum are identical across the available rows.

The most recent updates were made on 2026‑02‑10 at 21:00 UTC for five of the six parameters, showing that the latest information is less than a month old. The exception is PM10, whose last entry dates back to 2025‑01‑13 at 23:00 UTC, meaning that this particular measurement is over a year stale while the others are fresh. Because all values come from the same location, the data represent conditions at Warmley Common rather than a citywide average.

All six pollutants have a single reported figure, so there is no spread to describe. PM1 sits at 9.09 µg/m³, PM2.5 at 14.53 µg/m³ and PM10 at 14.63 µg/m³. Relative humidity is recorded as 71.81 % and temperature as 13.04 °C. The particle counter (UM003) reads 1 659.06 particles per cm³. With only one site contributing, the dataset cannot capture spatial variation across South Gloucestershire; conditions elsewhere in the district may differ from those measured at Warmley Common, especially for the older PM10 reading.
