Rush-hour queues near the A34 are usually when readings climb the most. Tower of London's position in London, City of means air quality is mostly determined by local road traffic and the compact scale of the centre. Easterly winds do most of the work keeping things in check, more so than any local policy or infrastructure change.

When is air pollution at its worst in Tower of London?
Tower of London doesn't have one fixed air quality level — it swings between two extremes each year. In deep winter, a lack of wind lets A34 traffic fumes and woodsmoke settle instead of blowing through. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes.
Are air quality levels in Tower of London 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.
