The dominant factor behind Anacortes's air quality is Puget Sound sea breeze; onshore wind keeps air quality consistently excellent. None of this is unusual for a place with Anacortes's particular geography and climate. Longer-term residents of Anacortes tend to plan outdoor activity around these predictable shifts.

When is air pollution at its worst in Anacortes?
Air quality across Anacortes rises and falls with the seasons. In short, spring is often the freshest stretch, sandwiched between winter rain and summer fire season, whereas August and September wildfire smoke can dominate the season, occasionally driving particulate levels sharply higher for several days. Coastal areas see relatively little of the smoke that can settle into inland valleys during fire season.
Are air quality levels in Anacortes 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.
