Sedona experiences air quality conditions shaped chiefly by high desert dryness, and air is usually excellent, aside from occasional dust on windy days. Most days bring generally favorable conditions here, with occasional exceptions tied to shifting weather patterns. Local topography and prevailing winds both play a role in how quickly conditions change.

Frequently Asked Questions

Is air quality bad in Sedona right now?

On 9 August 2026, overall air quality in Sedona is fair. PM2.5 is the main pollutant at 26.1/100. Pollution peaks around 11:00 AM (O3: 42.2/100).

Will air quality be worse tomorrow in Sedona?

On 10 August 2026, air quality conditions in Sedona will be similar to today, with AQI forecast at fair at 40.0/100. Pollution peaks around 5:00 PM (NO2: 40.0/100).

When is air pollution at its worst in Sedona?

Sedona's air quality has a clear seasonal rhythm — winter is generally the cleanest season, with cooler temperatures and less dust in the air, whereas spring winds can kick up sudden dust storms that spike particulate levels sharply for a day or two. Monsoon storms in July and August can either clear the air with rain or stir up dust ahead of the storm front.

Are air quality levels in Sedona 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.
