Umuarama's air quality reflects the northwestern Paraná plateau at 376 metres, with vehicle emissions from the BR-272 and surrounding agricultural processing contributing local sources. Dry season burning from surrounding Paraná and Mato Grosso do Sul agricultural land contributes seasonal PM2.5 variation, making agricultural burning the dominant seasonal air quality influence throughout the year.
