Air quality is typically excellent for much of the year, though summer weekends bring a rise in vehicle traffic from visitors, and occasional wildfire smoke can drift in during hot, dry stretches. Weekday air quality is often noticeably better than on busy summer weekends when visitor numbers peak.
Are air quality levels in Tadoussac 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.
