Air quality today

The air quality in Fingal is currently classified as Good. According to the latest assessment, the main pollutant identified is PM2.5. The reference value for PM2.5 stands at 1.80 µg/m³, while the reference value for PM10 is 4.36 µg/m³. These figures are derived from 11 valid measurements collected for the current reporting period.

Data is shown via OpenAQ, which aggregates observations from participating monitoring stations. The reported concentrations place Fingal within the Good category, indicating that the measured pollutant levels are below thresholds associated with higher classifications. This concise summary reflects the current state based on the available data set. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Fingal data set pulls OpenAQ readings from four monitoring sites and contains sixteen individual rows of observations. Sixteen rows are split across the pollutants measured in the city: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of 1 µm (PM1), 2.5 µm (PM2.5) and 10 µm (PM10), relative humidity, temperature and the particle count metric UM003. For most pollutants there are several recent entries – eleven of the rows were recorded within the last thirty days, with the newest timestamps on 2026‑02‑10 (20:00 UTC for PM2.5, PM1, relative humidity, temperature and UM003, and 13:00 UTC for NO₂ and PM10). Five rows are older, the oldest being the CO measurement from 2025‑11‑28 (18:00 UTC). Ozone is listed among the monitored species but no recent values appear in the current collection.

Across the available data the measured concentrations show a broad spread. PM2.5 values range from 1.6 µg/m³ up to 9.71 µg/m³ with a median of about 2.31 µg/m³, while NO₂ varies from 2.11 µg/m³ to 52.96 µg/m³ and has a median near 17.3 µg/m³. PM10 spans 2.97 µg/m³ to 20.27 µg/m³ with a median of 4.36 µg/m³. In contrast, PM1, relative humidity, temperature and UM003 each have a single recent reading – 0.336 µg/m³, 66.81 %, 12.48 °C and 224.57 particles/cm³ respectively – and CO is represented by a single older value of 930 µg/m³. This pattern indicates that the dataset is richer for the larger particulate fractions and NO₂, while the finer particles, humidity, temperature and CO are captured at only one site each, limiting spatial detail for those variables.

Overall the Fingal air‑quality snapshot provides recent, multi‑site coverage for several key pollutants, but the uneven number of observations and the older CO record mean that conditions can differ across the city and over time, especially for the less‑frequently sampled parameters.

Data notes

These data are based on 11 valid measurements and have been updated within 30 days, with the most recent reading recorded on 2026-02-10 at 20:00 UTC. The figures represent a city‑wide average at the time of collection. Please note that air quality can vary by location and time within Fingal, so conditions may differ from the snapshot shown.
