In Lead, clean Black Hills mountain air is the main influence on air quality, and air quality is generally excellent outside of wildfire-smoke episodes. None of this is unusual for a place with Lead's particular geography and climate. Wind direction on any given day can shift things noticeably from the seasonal norm.

Frequently Asked Questions
Is air quality bad in Lead right now?
On 9 August 2026, overall air quality in Lead is fair. NO2 is the main pollutant at 39.9/100. Pollution peaks around 7:00 AM (O3: 40.9/100).
Will air quality be worse tomorrow in Lead?
On 10 August 2026, air quality conditions in Lead will be similar to today, with O3 forecast at fair at 34.0/100. Pollution peaks around 11:00 PM (NO2: 43.2/100).
When is air pollution at its worst in Lead?
Lead's air quality follows a clear seasonal pattern. In short, once the harvest dust settles, winter typically offers the cleanest stretch of the year, whereas summer heat and humidity drive ozone formation, and agricultural dust can spike particulate levels during planting and harvest. Wide-open terrain generally helps disperse pollution quickly once the wind picks up.
Are air quality levels in Lead 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.
