Sedona's Red Rock State Park air quality benefits from the elevated Arizona Verde Valley position at 1,200 metres, with the dramatic red rock canyon and mesa topography creating distinctive local wind patterns. The surrounding Coconino National Forest provides natural filtration, while vehicle traffic on AZ-89A and concentrated tourism contribute modest local sources and the extraordinary red rock landscape's iron oxide mineral dust can contribute distinctive local PM10, with summer wildfire smoke as the primary seasonal concern throughout the year.

Frequently Asked Questions
Is air quality bad in Red Rock State Park right now?
On 20 September 2026, overall air quality in Red Rock State Park is moderate. AQI is the main air quality indicator at 43.8/100. Pollution peaks around 10:00 AM (PM10: 43.8/100).
Will air quality be worse tomorrow in Red Rock State Park?
On 21 September 2026, air quality conditions in Red Rock State Park will be similar to today, with AQI forecast at moderate at 41.2/100. Pollution peaks around 12:00 AM (PM2.5: 41.2/100).
When is air pollution at its worst in Red Rock State Park?
Red Rock State Park follows Sedona's typical seasonal air quality pattern, as the cooler winter months typically bring the cleanest air of the year; by contrast, summer heat drives ozone formation, and blowing dust from spring winds can push particulate levels up abruptly. Sudden haboob-style dust storms can appear with little warning during the spring wind season.
Are air quality levels in Red Rock State Park 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.
