Worst air pollution Burgess Hill, today and tomorrow

On 9 August 2026, overall air quality in Burgess Hill is fair. O3 is the main pollutant at 28.4/100. Pollution peaks around 8:00 PM (NO2: 40.4/100).

On 10 August 2026, air quality conditions in Burgess Hill will be similar to today, with AQI forecast at fair at 37.2/100. Pollution peaks around 9:00 PM (NO2: 37.2/100).

Here's the thing about Burgess Hill: air quality has a clear seasonal rhythm. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let M4 traffic emissions linger rather than disperse. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.

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.
