Benevides' air quality reflects the greater Belém metropolitan area in the Pará Amazon estuary zone, with vehicle emissions from the BR-316 and surrounding agricultural and urban growth contributing local sources. Atlantic equatorial airflows provide background ventilation, while dry season Amazon burning from surrounding Pará deforestation generates intense PM2.5 episodes between July and November that dominate the seasonal air quality across the entire greater Belém metropolitan corridor throughout the burning season.

Frequently Asked Questions
Is air quality bad in Benevides right now?
On 9 August 2026, overall air quality in Benevides is good. AQI is the main air quality indicator at 19.4/100. Pollution peaks around 12:00 AM (O3: 19.4/100).

When is air pollution at its worst in Benevides?
You're most likely to notice worse air in Benevides when native Amazon forest remnants and secondary vegetation pollen peaks, or due to vehicle emissions from the BR-316 and surrounding agricultural and urban growth; the rest of the calendar year is generally more forgiving for air quality.
Are air quality levels in Benevides 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.
