Old Macdonald air quality benefits from its exceptional Bandon Oregon Pacific Ocean coastal position alongside Pacific Dunes, with consistent and powerful Pacific westerlies providing outstanding maritime ventilation. Vehicle traffic contributes very modest local sources, while the extraordinary open Pacific coastal dune exposure generally maintains among the Pacific Northwest's most reliably ventilated major golf venues, with summer wildfire smoke as the primary seasonal concern throughout the year.

When is air pollution at its worst in Old Macdonald – Old Macdonald Course?
Old Macdonald – Old Macdonald Course experiences the same seasonal air quality swings as the rest of Coos Bay — the wet winter and spring months are generally the cleanest, with regular rain limiting particulate buildup, whereas August and September wildfire smoke can dominate the season, occasionally driving particulate levels sharply higher for several days. Prevailing onshore winds usually keep pollution moving rather than letting it settle.
Are air quality levels in Old Macdonald – Old Macdonald Course 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.
