Most polluted cities in Andalusia, Spain

11 measured cities, last 30 days; 2 above the WHO 24-hour guideline. Worst: Alcalá de Guadaira at 16.1 µg/m³, #323 in the world.

26 monitors in Spain stopped reporting on 6 Oct, 05:00 Madrid time. Cities that rely on them are missing from the 24-hour board and may drop from the longer ones; that isn't clean air, and they return when the data does.

Ranked by unhealthy days: the share of each city's measured days with a daily mean over 35.4 µg/m³ (US AQI 101+), Unhealthy for Sensitive Groups or worse on the US EPA's scale. Ties go to the higher average.

Estimated: cities without a monitor

Andalusia cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.
