Air quality today

The air quality in Algeciras today is classified as Good. The primary pollutant measured is PM2.5. Current readings show PM2.5 at 3.12 µg/m³ and PM10 at 5.25 µg/m³, based on seven valid measurements. These concentrations are consistent with the Good classification for the day. The most recent measurement was recorded at 2026-02-23 12:00 UTC. No other pollutants exceeded the reporting threshold.

Data is shown via OpenAQ. The information reflects the current monitoring status for Algeciras, Andalusia, Spain. The dataset is refreshed as new valid measurements become available. Users can consult the OpenAQ platform for additional details on measurement locations and timestamps. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Algeciras air‑quality record draws on measurements from two official monitoring stations, providing eleven recent rows of data across the seven listed pollutants. Eight of those rows have been updated within the past 30 days, while three are classified as older; none are from today or the last week. For most compounds the newest timestamps are from early February 2026, indicating a fairly fresh snapshot, but the nitrogen monoxide (NO) values date back to 2024‑02‑21, making that particular series the only one that is more than two years old.

Carbon monoxide (CO) is reported at a constant 315 µg/m³ from the ALGECIRAS EPS site, with the last reading logged on 2026‑02‑09 03:00 UTC. Ozone (O₃) shows the same pattern, also 86 µg/m³ at the same station and time. Sulphur dioxide (SO₂) ranges from a minimum of 1 µg/m³ to a maximum of 11 µg/m³, with a median of 6 µg/m³; the spread (10th‑90th percentiles) runs from 2 to 10 µg/m³, all recorded on 2026‑02‑09 03:00 UTC at ALGECIRAS EPS. Particulate matter 10 µm (PM₁₀) varies between 5.25 and 30.51 µg/m³, median 17.88 µg/m³, with the 10th‑90th range of 7.78 to 27.98 µg/m³, also from the 2026‑02‑09 03:00 UTC update. Fine particles (PM₂.₅) are available from a different sensor (E4:RINCONCILLO) and show a single value of 3.12 µg/m³ recorded on 2026‑02‑05 13:00 UTC. Nitrogen dioxide (NO₂) spans 0 to 2 µg/m³, median 1 µg/m³, with the 10th‑90th interval of 0.2 to 1.8 µg/m³, all from the 2026‑02‑09 03:00 UTC reading at ALGECIRAS EPS. In contrast, NO is limited to two rows, both from ALGECIRAS EPS, with values ranging from 2 to 4 µg/m³ and a median of 3 µg/m³, but the most recent entry dates to 2024‑02‑21 00:00 UTC. This mix of recent and older timestamps, together with the differing number of observations per pollutant, highlights that coverage is uneven: most pollutants have fresh, multi‑row data, while NO relies on a sparse, dated record, meaning city‑wide conditions can differ by location and time.
