Oakland's Temescal air quality reflects the vibrant Telegraph Avenue neighbourhood, with vehicle traffic on Telegraph Avenue and the surrounding mixed residential and commercial character contributing local sources. The Bay Delta breeze provides afternoon ventilation, while the neighbourhood's walkable character and the tree-lined streets generally maintain moderate Oakland metropolitan readings and Temescal tracks at typical inner Oakland neighbourhood levels throughout the year.

When is air pollution at its worst in Temescal?
Air quality at Temescal shifts across the year — late winter and spring tend to have the cleanest conditions, once winter rains settle in, whereas summer and early autumn bring the highest risk, with heat-driven ozone and wildfire smoke both peaking from July through October. Dry summer conditions with virtually no rain mean pollution and smoke can linger for extended stretches once they arrive.
Are air quality levels in Temescal 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.
