Worst air pollution Klamath Falls, today and tomorrow

On 30 August 2026, overall air quality in Klamath Falls is poor. AQI is the main air quality indicator at 72.8/100. Pollution peaks around 10:00 PM (NO2: 72.8/100).

On 31 August 2026, air quality conditions in Klamath Falls will be similar to today, with AQI forecast at poor at 61.2/100. Pollution peaks around 10:00 PM (NO2: 61.2/100).

Air quality across Klamath Falls rises and falls with the seasons: the wet winter and spring months are generally the cleanest, with regular rain limiting particulate buildup, but late summer wildfire smoke is the biggest concern, sometimes pushing air quality into unhealthy territory for days at a stretch. Coastal areas see relatively little of the smoke that can settle into inland valleys during fire season.

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.
