Worst air pollution Las Vegas, today and tomorrow

On 9 August 2026, overall air quality in Las Vegas is fair. AQI is the main air quality indicator at 38.9/100. Pollution peaks around 9:00 AM (O3: 38.9/100).

On 10 August 2026, air quality conditions in Las Vegas will be better than today, with AQI forecast at medium at 40.4/100. Pollution peaks around 9:00 AM (O3: 40.4/100).

Air quality across Las Vegas rises and falls with the seasons. In short, winter typically brings a welcome break from both heat-driven ozone and blowing dust, whereas intense summer heat combines with occasional dust events to create the year's worst episodes. Monsoon storms in July and August can either clear the air with rain or stir up dust ahead of the storm front.

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.
