Air quality today

The air quality in Salford today falls into the Moderate category. The primary pollutant identified is PM2.5, with a reference concentration of 11.0 µg/m³, while the reference value for PM10 stands at 18.0 µg/m³. Measurements from eight valid monitoring points contribute to this assessment and are displayed via OpenAQ.

These figures reflect the current conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Salford air‑quality dataset currently includes measurements for four key pollutants – nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Data come from two monitoring sites, each providing a recent record, giving a total of eight rows across the four pollutants. All values were last refreshed on 2026-02-10 20:00 UTC, so the information reflects conditions as of that date and time.

For NO2 the observed concentrations range from a minimum of 25 µg/m³ to a maximum of 28 µg/m³, with a median of 26.5 µg/m³; the 10th percentile sits at 25.3 µg/m³ and the 90th percentile at 27.7 µg/m³. Ozone values span 21 µg/m³ to 26 µg/m³, median 23.5 µg/m³, with a tighter inter‑percentile spread (10th percentile 21.5 µg/m³, 90th percentile 25.5 µg/m³). PM10 shows the broadest variation, from 9 µg/m³ up to 18 µg/m³, median 13.5 µg/m³ and a 10‑90 range of roughly 9.9 µg/m³ to 17.1 µg/m³. PM2.5 is the most constrained, ranging only between 8 µg/m³ and 11 µg/m³, median 9.5 µg/m³, with a 10‑90 spread of about 8.3 µg/m³ to 10.7 µg/m³.

Because each pollutant is represented by just two stations, the spatial coverage across Salford is limited; conditions can differ between neighbourhoods and may not be captured fully by these points. Nevertheless, the dataset is uniformly recent, with no older or unknown timestamps, providing a consistent snapshot of air quality for the city on the specified date.

Data notes

The data shown for Salford is based on eight valid measurements and was refreshed recently – it is Updated within 3 days, with the most recent update recorded at 2026‑02‑10T20:00:00+00:00. This snapshot reflects conditions captured at that time; however, air quality can vary across different neighbourhoods and throughout the day, so values may differ from those experienced elsewhere in the city.
