Air quality today
The air quality in Palos de la Frontera today is classified as Good. The primary pollutant identified is PM10. Six valid measurements were used to determine the current rating. These observations are provided through OpenAQ. The six measurements were taken during the latest monitoring interval.
The reported PM10 concentration corresponds to the reference value of 10.4 µg/m³, indicating that the measured level matches the standard used for assessment. PM10 values are reported in micrograms per cubic meter. The Good classification indicates that the PM10 level does not exceed the reference threshold. No reference value is supplied for PM2.5 in this dataset. 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
The air‑quality record for Palos de la Frontera includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm (PM10) and sulphur dioxide (SO₂). The data come from two monitoring stations, providing a total of eight observation rows. Six of those rows were recorded within the last thirty days, while two rows are older than thirty days. The most recent timestamps are from 2026‑02‑09 03:00 UTC for NO₂, PM10 and SO₂, whereas the NO measurement was last updated on 2024‑02‑21 00:00 UTC and is flagged as older data.
Across the recent observations, NO shows the widest concentration spread, ranging from 3.0 µg/m³ up to 15.0 µg/m³ with a median of 9.0 µg/m³; the 10th and 90th percentiles sit at 4.2 µg/m³ and 13.8 µg/m³ respectively. PM10 values vary between 1.04 µg/m³ and 10.4 µg/m³, a median of about 5.72 µg/m³, and a percentile range of roughly 2.0 µg/m³ to 9.5 µg/m³. SO₂ is recorded between 1.0 µg/m³ and 3.0 µg/m³, with a median of 2.0 µg/m³ and percentiles at 1.2 µg/m³ and 2.8 µg/m³. In contrast, NO₂ is constant at 1.0 µg/m³ for the available record, showing no observed variation.
The dataset is unevenly distributed across stations: the NO reading originates from the PALOS site, while NO₂, PM10 and SO₂ are all reported from the TORREARENILLA site. This limited station network means that spatial coverage within the city is modest, and the older NO record indicates that not all pollutants are captured with the same frequency. Consequently, while recent data give a snapshot of current conditions for three pollutants, the overall picture for Palos de la Frontera remains dependent on a small number of measurement points and occasional older entries.
