Osogbo's air quality reflects the flat southwestern Nigeria Oshun River plateau at 300 metres, with vehicle density, informal manufacturing, and charcoal burning generating elevated PM2.5 and black carbon. The tropical wet season provides periodic cleansing, while dry season Harmattan dust elevates PM10 and Osogbo generally maintains moderate to elevated southwestern Nigerian state capital readings throughout most of the year.
