Worst air pollution Hingham, today and tomorrow

On 9 August 2026, overall air quality in Hingham is medium. AQI is the main air quality indicator at 53.0/100. Pollution peaks around 5:00 PM (O3: 53.0/100).

On 10 August 2026, air quality conditions in Hingham will be worse than today, with AQI forecast at fair at 20.8/100. Pollution peaks around 3:00 PM (O3: 20.8/100).

Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes. Hingham doesn't have one fixed air quality level — it swings between two extremes each year. In deep winter, a lack of wind lets A2 traffic fumes and woodsmoke settle instead of blowing through. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days.

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.
