Worst air pollution New England Aquarium - Boston, today and tomorrow

On 18 July 2026, overall air quality in New England Aquarium is medium. AQI is the main air quality indicator at 56.1/100. Pollution peaks around 1:00 PM (O3: 56.1/100).

On 19 July 2026, air quality conditions in New England Aquarium will be similar to today, with AQI forecast at medium at 59.4/100. Pollution peaks around 1:00 PM (O3: 59.4/100).

New England Aquarium follows Boston's typical seasonal air quality pattern. In short, frequent frontal systems in spring and fall usually keep the air cleanest then, whereas summer heat and regional haze drifting up from the Midwest and South drive ozone spikes. Winter cold fronts tend to clear the air quickly, so extended pollution episodes are relatively uncommon.

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.

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.
