Tucuruí's air quality reflects its position on the Tocantins river in Pará, with the Tucuruí hydroelectric dam complex operations and vehicle emissions from the PA-150 contributing local sources. The large Tucuruí reservoir provides humidity and limited ventilation, while dry season burning from surrounding Pará Amazon deforestation generates intense PM2.5 episodes between June and October that dominate the regional air quality across the entire southeastern Pará corridor.

Frequently Asked Questions
Is air quality bad in Tucuruí right now?
On 9 August 2026, overall air quality in Tucuruí is good. AQI is the main air quality indicator at 19.6/100. Pollution peaks around 6:00 AM (O3: 19.6/100).
Will air quality be worse tomorrow in Tucuruí?

When is air pollution at its worst in Tucuruí?
Tucuruí residents notice reduced air quality mainly when native Amazon forest trees and reservoir shoreline vegetation pollen peaks, and during spells of the Tucuruí hydroelectric dam complex operations and vehicle emissions from the PA-150; things typically settle down again once the weather pattern shifts.
Are air quality levels in Tucuruí based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
