Ilorin's air quality reflects the flat north-central Nigeria Kwara plateau at 307 metres in the forest-savanna transition zone, with vehicle density, cotton processing, and informal industrial corridor generating elevated PM2.5. Harmattan dust from the Sahara delivers elevated PM10 from November to March, while the transition zone location creates a distinctive seasonal contrast between harmattan and wet season conditions throughout the year.
