Ouricuri's air quality reflects the Pernambuco semi-arid Sertão interior at 392 metres in the Araripe plateau foothills, with vehicle emissions from the BR-316 and surrounding cattle, goat, and subsistence farming contributing local sources. Drought conditions and Caatinga burning contribute seasonal PM10 elevation, while the Araripe highland creates topographic variation and the semi-arid climate creates naturally dusty conditions during dry windy periods throughout the year.
