Worst air pollution Pulborough, today and tomorrow

On 9 August 2026, overall air quality in Pulborough is fair. AQI is the main air quality indicator at 28.4/100. Pollution peaks around 3:00 PM (O3: 28.4/100).

On 10 August 2026, air quality conditions in Pulborough will be similar to today, with AQI forecast at fair at 25.0/100. Pollution peaks around 1:00 AM (O3: 25.0/100).

You can roughly predict Pulborough's air quality just by knowing the time of year. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the M74 closer to ground level. Spring and autumn tend to be the calmer, more moderate stretches by comparison.

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.
