Worst air pollution Piccadilly, today and tomorrow

On 25 August 2026, overall air quality in Piccadilly is good. AQI is the main air quality indicator at 14.7/100. Pollution peaks around 12:30 PM (O3: 14.7/100).

On 26 August 2026, air quality conditions in Piccadilly will be similar to today, with AQI forecast at good at 18.5/100. Pollution peaks around 11:30 PM (PM1: 18.5/100).

Winter is usually when particulate matter climbs highest locally, as rural heating sources add up under inversions that keep smoke from dispersing. Once summer sets in, bushfire smoke haze becomes the bigger local concern on affected days, since bushfire smoke haze on affected days can outweigh the ozone increase heat alone would produce.

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.
