Coari's air quality faces seasonal challenges as an Amazonas state city on the Solimões river and Coari Lake, with dry season burning from surrounding Amazon deforestation generating regional PM2.5 episodes between June and October. Vehicle emissions from local roads and the Petrobras Urucu natural gas and oil extraction operations nearby contribute industrial emissions year-round, while the Amazon river corridor provides limited ventilation and calm dry season conditions allow smoke to accumulate.
