Worst air pollution Willoughby, today and tomorrow

On 9 August 2026, overall air quality in Willoughby is fair. AQI is the main air quality indicator at 31.7/100. Pollution peaks around 11:00 AM (O3: 31.7/100).

On 10 August 2026, air quality conditions in Willoughby will be similar to today, with AQI forecast at fair at 32.6/100. Pollution peaks around 1:00 PM (O3: 32.6/100).

Willoughby typically sees its highest particulate readings in winter, when heating and traffic emissions linger under calm, cold skies. Summer heat and sunlight typically push ozone to the top of the seasonal concerns here. Drifting wildfire smoke from farther away sometimes adds to the summer air quality burden. Spring and fall, with milder temperatures and steadier wind, generally offer the cleanest air of the year.

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.
