Air quality today
The air quality in Albufeira today is classified as Good. The main pollutant identified is PM10, with a reference value of 1.5 µg/m³ based on the available data. Three valid measurements were recorded for this assessment.
Data are shown via OpenAQ and reflect the current monitoring results for the city. 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 Albufeira currently includes four measured pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). All of them come from a single monitoring site identified as Malpique, so the city’s coverage is limited to one location rather than a network of stations. Each pollutant has exactly one recent observation; the latest timestamps are all 2026‑02‑10 21:00 UTC, which falls within the “updated within 7 days” freshness category.
The numeric values show virtually no variability because each series contains only a single data point. For NO₂ the reading is 1.9 µg/m³, for O₃ it is 44.1 µg/m³, and PM₁₀ registers at 1.5 µg/m³. The SO₂ measurement is recorded as –1.0 µg/m³, a negative figure that typically signals an instrument or data‑processing issue rather than a true atmospheric concentration. Because there is only one row per pollutant, statistical summaries such as minimum, median and maximum are identical to the single observed value.
Overall, the dataset provides a very narrow snapshot of air quality in Albufeira: it reflects conditions at one point in time and at a single site, with all values freshly reported but lacking any temporal spread or spatial diversity. Consequently, while the numbers give an immediate sense of the current reading at Malpique, they do not capture how concentrations might differ across other parts of the city or change throughout the day.

Data notes
The current data for Albufeira is based on three valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10 21:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and vary throughout the day, so values may not represent the entire city at all times.
