Worst air pollution Lavaux Vineyard Terraces - Vevey, today and tomorrow

On 30 August 2026, overall air quality in Lavaux Vineyard Terraces is fair. AQI is the main air quality indicator at 27.3/100. Pollution peaks around 11:00 AM (O3: 27.3/100).

On 31 August 2026, air quality conditions in Lavaux Vineyard Terraces will be similar to today, with AQI forecast at fair at 26.0/100. Pollution peaks around 4:00 PM (O3: 26.0/100).

Winter stillness is the main driver of poor air quality at Lavaux Vineyard Terraces, letting vehicle traffic and international commuter activity build up in the basin until the wind eventually returns. Summer usually brings much better dispersion, aside from the odd ozone spike during a hot, still afternoon, and spring and autumn tend to be the steadiest months.

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.
