Air quality today

The air quality today in Wirral is classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 12.0 and a PM10 reference value of 14.0, based on six valid observations collected via OpenAQ.

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

What the data includes

The data set for Wirral includes measurements of nitrogen dioxide (NO₂), ozone (O₃), fine particulate matter (PM₂.5) and coarse particulate matter (PM₁₀). Six rows of observations are recorded across two monitoring stations, giving a modest but useful snapshot of air quality in the area. The most recent readings were taken on 2026‑02‑10, with timestamps ranging from 19:00 UTC for ozone to 20:00 UTC for the other three pollutants, so all values are fresh within the last seven days.

Across the six rows the recorded concentrations show a fairly narrow spread. For NO₂ the values range from 14 µg/m³ up to a maximum of 28 µg/m³, with a median of 21 µg/m³ and the central 80 % of observations falling between about 15 µg/m³ and 27 µg/m³. PM₂.5 values are clustered tightly between 11 µg/m³ and 12 µg/m³, with a median of 11.5 µg/m³; the 10th and 90th percentiles sit at roughly 11.1 µg/m³ and 11.9 µg/m³ respectively. Ozone and PM₁₀ each have only a single reported value – 31 µg/m³ for ozone and 14 µg/m³ for PM₁₀ – both recorded at the Wirral Tranmere station on the same day.

The coverage is uneven: while NO₂ has two separate stations contributing data, PM₂.5, O₃ and PM₁₀ are represented by a single station each. This means spatial variation in those three pollutants cannot be assessed within Wirral from this set alone. Overall, the dataset provides recent, point‑specific measurements but is limited in breadth, so conditions may differ across other neighbourhoods or at times outside the narrow window captured here.
