Air quality today

The air quality in York today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 18.0 and a PM10 reference value of 24.0, based on seven valid observations collected via OpenAQ.

These figures provide a snapshot of the current atmospheric conditions in the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

York’s air‑quality data set contains four measured pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). The information comes from two monitoring stations, each providing a single recent reading for every pollutant. All of the latest updates were recorded on 2026‑02‑10 at 20:00 UTC, so the data are fresh within the past week.

For NO₂ the values range from a low of 14 µg/m³ to a high of 24 µg/m³, with a median of 19 µg/m³ and the middle 80 % of observations falling between 15 µg/m³ (10th percentile) and 23 µg/m³ (90th percentile). PM10 shows very little variation: the minimum is 23 µg/m³, the maximum 24 µg/m³, the median 23.5 µg/m³ and the 10th‑90th percentile band stretches only from 23.1 to 23.9 µg/m³. PM2.5 spans a broader interval, from 13 µg/m³ up to 18 µg/m³, with a median of 15.5 µg/m³ and an inter‑percentile range of 13.5–17.5 µg/m³. Ozone is reported as a single value of 18 µg/m³, because only one station supplies this measurement.

The dataset therefore offers complete coverage for each pollutant but from a limited number of locations – just two rows per pollutant – and all observations are recent. Because the spatial sampling is modest, the figures represent conditions at the specific monitoring sites rather than city‑wide averages; actual concentrations can differ across other neighbourhoods or at different times of day.

Data notes

The data shown reflects seven valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 20:00 UTC. This snapshot provides a current view of York’s air quality but conditions can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
