Air quality today

The air quality in Maó today is classified as Good. The primary pollutant identified is PM10, with the measured concentration compared to a reference value of 10.0 µg/m³. Fourteen 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.

What the data includes

The dataset for Maó includes measurements of nitrogen dioxide (NO₂), ozone (O₃), sulfur dioxide (SO₂), particulate matter ≤ 10 µm (PM10) and nitric oxide (NO). In total there are twenty rows of data collected from four monitoring stations across the city. The most recent readings for NO₂, O₃, SO₂ and PM10 were all taken on 2026‑02‑09 at 15:00 UTC (for the first three pollutants) or 03:00 UTC (for PM10), so those four substances have very fresh information available. By contrast, the latest NO value dates back to 2024‑03‑05 00:00 UTC, meaning that data for this pollutant is considerably older.

Across the recent observations, concentrations show a modest spread. NO₂ values range from 0.3 µg/m³ up to 4.9 µg/m³ with a median of about 2.0 µg/m³; O₃ varies between 62.0 and 93.4 µg/m³, centering around 75 µg/m³; SO₂ stays low, from 1.97 to 2.7 µg/m³ with a median near 2.1 µg/m³; PM10 is measured between 10.0 and 22.0 µg/m³, the median also being 10 µg/m³. NO, however, shows a much wider historic range of 0.2 to 44.0 µg/m³ with a median of 22.1 µg/m³, reflecting its older dataset.

The coverage is uneven: four pollutants have up‑to‑date readings from the same recent day, while NO relies on data that is almost two years old. Consequently, current air quality conditions in Maó can be described reliably for NO₂, O₃, SO₂ and PM10, but any assessment involving NO must acknowledge the dated nature of its information. The limited number of stations (four) means spatial variation within the city may not be fully captured, especially for pollutants with sparse or older records.

Data notes

The data shown for Maó reflects 14 valid measurements and is updated within 3 days, with the latest values recorded on 2026‑02‑09 at 15:00 UTC. While this snapshot provides a recent overview of citywide air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
