Worst air pollution San Diego Zoo Safari Park - San Diego, today and tomorrow

On 9 August 2026, overall air quality in San Diego Zoo Safari Park is fair. AQI is the main air quality indicator at 23.2/100. Pollution peaks around 4:00 AM (O3: 23.2/100).

On 10 August 2026, air quality conditions in San Diego Zoo Safari Park will be similar to today, with AQI forecast at fair at 21.0/100. Pollution peaks around 9:00 AM (O3: 21.0/100).

Like the rest of San Diego, San Diego Zoo Safari Park sees air quality change through the year. In short, the shortest stretch of clean air usually falls in the wetter winter months, whereas hot, sunny summer conditions drive persistent ozone problems, compounded by wildfire smoke risk into early autumn. Coastal breezes offer some relief compared to inland valley locations that see heavier smog buildup.

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.
