Like much of London, City of, Southwark & Borough Market's air quality is shaped less by industry these days and more by everyday road traffic. The area's changeable Atlantic weather help ventilate the town centre, keeping air quality at moderate levels typical for the region. Traffic on the A26 is the most significant local emissions source, especially at peak times.

When is air pollution at its worst in Southwark & Borough Market?
Southwark & Borough Market's air quality follows a familiar seasonal pattern most UK towns share. Through the colder months, readings near the A26 often rise, since chimney smoke and stagnant air stop pollutants clearing away. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Southwark & Borough Market 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.
