Air quality today
The air quality in Pembrokeshire today is classified as Good. The primary pollutant measured is PM2.5, with a reference value of 3.0 µg/m³, while the reference for PM10 stands at 4.0 µg/m³. Five valid measurements were recorded to determine these values.
Data are shown via OpenAQ and reflect the current assessment for the area. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
Pembrokeshire’s air‑quality feed draws from five monitoring rows, each reporting a single set of measurements that were last updated on 2026‑02‑10 20:00 UTC. All five pollutants—nitrogen dioxide (NO2), ozone (O3), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µg (PM2.5) and sulphur dioxide (SO2)—are represented, and every reading comes from the same station at Narberth (UKA00323). Because each pollutant has only one recorded value, the minimum, median and maximum are identical for each: NO2 sits at 2.0 µg/m³, O3 at 71.0 µg/m³, PM10 at 4.0 µg/m³, PM2.5 at 3.0 µg/m³ and SO2 at 1.0 µg/m³. This uniformity means there is no observed spread or variability within the current dataset.
The data are relatively fresh, with every measurement falling into the “updated within 7 days” category, so the snapshot reflects conditions from just a few days ago rather than historic averages. However, the coverage is limited to a single monitoring location; no additional rows provide alternative sites across Pembrokeshire. Consequently, while the figures give an up‑to‑date picture for Narberth, they do not capture spatial differences that may exist elsewhere in the county.
In practical terms, users should note that the dataset offers a concise but narrow view: five pollutants are available, each with one recent value from one station. The lack of multiple rows or older timestamps means there is no trend information and little insight into day‑to‑day fluctuations across Pembrokeshire. For a fuller understanding of air quality throughout the region, additional monitoring points would be needed.

Data notes
The data shown are based on five valid measurements and have been refreshed recently, with the latest update recorded at 2026‑02‑10T20:00:00+00:00 (Updated within 3 days). This snapshot reflects conditions at the time of sampling; air quality can vary by location and time within Pembrokeshire, so values may differ across the city and over short periods.
